DIY electric window repair

In detail: do-it-yourself electric window repair from a real master for the site my.housecope.com.

Electric windows (EP) - this is one of the elements of the vehicle, contributing to more comfortable driving. Like any other component of an electrical circuit, electric drives tend to break down periodically. What to do if the car window regulator does not work and for what reasons these components break down - read below.

What to do if the right one does not work or both ESs fail? The windows can break, making them unable to raise or lower the windows. It is possible that the EP is jamming or wedging, but before you repair and disassemble the system with your own hands, you need to understand its structure. The unit itself works by controlling electric motors installed in the vehicle door and designed to raise and lower the glass.

The system itself includes the following components:

electric motors;
switches located in the doors;
wiring;
glass.

General arrangement of the EP system

Why doesn't the power windows work or only the right power window doesn’t rise? In order to understand exactly why the malfunction occurred, it is advisable to familiarize yourself with the principle of operation of the unit. Typically, such a system has a trapezoidal design, which allows the glass to be raised and lowered by pressing the switches. The buttons themselves can be located in all car door cards or only in the driver's door. It is also worth noting that an electric motor is mounted in each door, which functions in two directions.

In addition, each system is equipped with a special relay, the purpose of which is to control the voltage supplied to the electric motors of the structure. Depending on the vehicle, some car models can be supplemented with automatic switches that are installed separately for each electric motor. The use of such structural elements makes it possible to ensure the normal operation of the entire system if the window regulator works poorly on only one door.

So, we smoothly approached the issue of malfunctions. What if the window regulator cannot go up or down? Before you remove the window regulator, disassemble and repair it in your car, let's look at the main reasons. If the rear windows or front windows do not work, the cause can be both electrical and mechanical.

Detailed design of the EP system

First of all, if the window lifter stops working, it is necessary to diagnose the safety element responsible for the functionality of the system. If you realize that the power window does not work because of the fuse, then you just need to replace it. But if the fuse is working, then it will be necessary to measure the voltage at the terminals of the electric motor. Such a task can be accomplished using a conventional 12 volt lamp or using a tester.

If you find that the driver's window or any other door does not work due to voltage, then you need to check further:

wiring;
relay;
system control unit.

Sometimes the car owner thinks that the window regulator has broken down if, after opening the glass, it automatically starts to close until the key turns in the ignition lock. As a rule, in this case, the problem lies in the contacts, which should be cleaned up.Much less often, but it still happens that the repair of power windows includes the replacement or repair of the button.

If, after measuring the voltage, you understand that there is current in the system, but it does not go down or, in principle, the window lifter does not work, most likely the problem is mechanical. As a rule, in this case, the device is interfering with something, so you will have to disassemble the door and look for the reason. Much less often, the reason lies in a failed electric motor (the author of the video is the channel In the garage at Sandro's).

How to raise the glass if the electronic board is broken - there are several options:

Purchase a window regulator repair kit and repair the device, and then fully use the system.
Try to take the glass from both sides with your hands and pull it up. If the glass falls after being lifted, then you will have to disassemble the door and substitute a support of the appropriate size under it.
If you can't lift the glass with your hands, you can take a fishing hook on the line and lower it into the door card. You need to try to pry the glass and lift it.

Window lifter repair may include different stages depending on the breakdown. In this case, we will tell you how to repair the window regulator by replacing its electric motor, as mentioned above, this problem is one of the most common.

The replacement process is considered using the example of the Lada Kalina car:

First you need to buy a new electric motor, which is sold in a gearbox housing. The door trim is dismantled - this operation cannot be performed in the cold, since the trim is fixed with plastic caps, which will quickly break.
Unscrew all screws and other fasteners securing the inner handle.
All wires must be disconnected; for greater convenience, you can dismantle the speakers. After these steps, the glass is unscrewed, which is fixed in the guides. In order for the glass to sink to the bottom, it is necessary to unscrew four more screws, for this a key 10 is used. There is a shutter at the bottom of the glass unit, it must be removed.
Directly the power window itself is mounted on nuts and guides, the electric motor itself is fixed with three more nuts. The unit can be pulled out through the access holes in the door. If you take apart the gearbox, the electric motor will crumble in two. In general, the gearbox must be dismantled and replaced with a new one, reassembling in the reverse order. Lubricate the gear cable before use.

For more information on how to replace a window regulator in a car with your own hands, find out from the video below (author - channel In the garage at Sandro's).

During the operation of the vehicle, one or both of the electric lifts may fail. What to do in such a situation? The window regulator may fail, because of this, it will not be able to lower and raise the glass, at the command of the driver. This could be caused by a wedge or a jammed mechanism. One of the solutions to the problem is to repair the window regulator. How do you get this job done? What are the elements of the device? What malfunctions do car owners face most often? Let's consider these issues in more detail.

In order to properly repair the window regulator, it is worth understanding its design. The mechanism works by means of two electric motors, which are installed in the doors of the car, and perform the function of raising / lowering the glass.

Generally speaking, the following elements are included in the power window:

Electric motors.
Glass.
Wires.
Switches (installed in the doors).

In order to understand the causes of the device malfunction and to repair the window regulator, it is important to understand the principle of operation of the device. As a rule, such a mechanism has a trapezoidal design, which allows the glass to be raised and lowered by pressing the switch button.The location of the buttons mentioned may vary. They can only be installed in the driver's door or installed in all doors. In addition, a bi-directional motor is installed in the door cavity.

Each system is equipped with a special relay that controls the voltage supplied to the electric motor. In some machines, circuit breakers are installed that are provided for each of the electric motors. Thanks to such details, the normal operation and reliability of the system is ensured. In the event of a malfunction of one window regulator, the rest continue to carry out their tasks.

Now let's move on to a more important issue - the causes of malfunctions. What to do in a situation if the glass does not rise or fall? Before disassembling the mechanism and repairing the window regulator, understand the probable causes of the problem. If the front and back devices do not work, the problem may be hidden in the electrical or mechanical part.

First, check the fuse that powers the power window mechanism. If it burns out, it is enough to replace the faulty element and check the system's performance. In the case when the check showed the integrity of the fusible insert, measure the voltage at the input of the electric motor. To do this, use a multimeter or 12 volt light bulb.
Next, check the following items:

Power wires.
Relay.
Mechanism control unit.

There are situations when the window lifter, after lowering the glass, automatically raises it back until the key is in the ignition lock. Many people take this situation for a breakdown. In fact, the cause of the malfunction lies in the contacts that are dirty and need to be cleaned.

In more rare cases, repairing a window regulator involves replacing or refurbishing a button.

If the checks have shown that there are no problems with the power supply of the glass lifting and lowering device, the reason may lie in another plane - mechanical. As a rule, the windows do not work due to the appearance of some kind of physical obstacle. In this case, disassemble the door and find the reason. Sometimes the problem is caused by a malfunction of the electric motor.

To raise the glass in the event of a breakdown of the window regulator, use one of the following ways:

Buy a new kit and have the window lifter repaired. This allows the system to be fully operational.
Grasp the glass with your hands, on both sides, and then pull it up. If the glass sheet is lowered immediately after lifting, disassemble the door and place a suitable support under the glass.
If the previous option does not work, attach the hook to the fishing line, then lower it into the cavity of the door. Your task is to pry off the glass and try to lift it.

One of the options for repairing a window regulator is to replace the electric motor of the mechanism. Practice shows that this problem is one of the most common, but you can fix it yourself. The replacement algorithm is considered on the example of the Lada Kalina car.

Buy a new electric motor that comes with a gearbox in a housing.
Remove the door trim. Remember that it is forbidden to do this work in the cold, due to the risk of damage to the plastic caps. The latter, under the influence of cold, become brittle and break.
Remove the screws and other fasteners that hold the inner handle.
Disconnect the wires and make your job easier by removing the speakers.
Removing wires from the door

Unscrew the glass fixed in the guiding elements. To lower the blade, unscrew the four screws, with a ten key.There is a curtain at the bottom of the glass unit - dismantle it.

Note that the window lifter is held in place with nuts and rails, and the electric motor is secured with three more nuts. If desired, the unit can be reached through the technological hole provided in the door.

Dismantling the gearbox

If the gearbox is disassembled, the electric motor will split into two parts. It is best to remove this subassembly and install the new part by reassembling in the reverse order. Before checking and operating the mechanism, the gear cable must be lubricated with grease. This completes the window regulator repair.

Comfort in the car is provided not only by all kinds of systems, which are becoming more and more, but also by fairly simple mechanisms, such as power windows. After all, any budget model that does not provide air conditioning, navigation, and the audio system consists of only a few standard speakers, is necessarily equipped with mechanisms for raising and lowering side windows.

On cars, electric and mechanical power windows have become widespread. In the former, the glass is raised and lowered by an electric motor, which ensures ease of use and ease of control. The driver or passenger just needs to press the appropriate button to move the side glass down or up.

In power windows, the driver ensures the movement of the glass using a special gearbox, which is manually driven into rotation. That is, to lower or raise the glass, it is necessary to rotate the handle installed on the door. Windows with this type of drive are less convenient to use, moreover, they are practically superseded by electric ones.

Window lifters are of several types, differing in design:

Moreover, these differences relate to the actuators of the lifts, that is, with the help of which the lifting and lowering is performed. The second component is the drive mechanism.

To consider possible breakdowns of the power windows, let's look at their design.

Let's start with the drive mechanism, as already noted, it can be of two types - mechanical (aka manual) and electrical.

Mechanical is a small gear reducer. A cable actuator is usually used with this type of drive. Therefore, such a gearbox consists of two gears that are meshed with each other. The pinion gear is small in size, and it is it that the driver rotates by means of the handle mounted on the door. The driven one is much larger in size, it is a drum for winding the cable. Due to the different sizes of these gears, a relative ease of opening and closing the glass is achieved.
In the electric drive, a gearbox is also used, but already of the "worm-gear" type. There is a worm on the shaft of the electric motor, which is meshed with a gear. The drive motor itself is of a reversible type, that is, when the polarity is changed, its rotation side changes, which allows the use of just one element to both lower and raise the glass. Such a drive is used with all types of actuators.

- window handle; 2 - handle lining; 3 - power window handle socket; 4 - window regulator mechanism; 5 - upper rollers; 6 - screws for fastening the pressure plates; 7 - pressure plates; 8 - lowering glass brackets; 9 - lowering glass; 10 - cable; 11 - lower roller; 12 - bolt; 13 - tension roller

Now, with regard to the executive mechanisms. The cable type can be used with both types of drives. Moreover, for mechanical and electrical mechanisms, their design is different, and significantly.

We will consider the design of a mechanical drive and a cable actuator using the VAZ-2107 as an example.In addition to the gearbox, it includes 4 rollers between which the cable moves, with ends fixed on the drum. One of the rollers is tensioning and ensures the proper tension of the cable for the entire period of operation, since in the process it is stretched.

Two rollers are upper and they are connected by means of tension plates with glass brackets. Because of this, when lowering or lifting, the rollers move with the glass. The last roller is the lower one, it is fixed and it is fixed on the door.

A cable is laid between these rollers in a special way. Moreover, it is not looped back. When lifting or lowering, the end on one side of it is unwound from the drum of the gearbox, and the other is wound. Thanks to this, it is possible to move the upper rollers, and with them the side glass.

In an electric drive, the cable actuator has a different design. It includes a guide at the ends of which rollers are installed. The electric motor with a gearbox is placed slightly to the side of this guide. The drive cable is laid between the guide rollers and goes to the gearbox drum, where it is fixed.

In the area between the guide rollers, a slider is attached to the cable, which in turn is connected to the glass. When the electric motor is turned on, one side of the cable begins to wind on the drum, and the other to unwind. Due to this, the cable moves between the rollers, and with it the slide with the glass.

The linkage actuator works in a different way. There is a lever, at one end of which a semicircular toothed sector is made, connected to the driven gear of the reducer. Its other end is connected to a strip on which the glass is planted. The lever from the sector side by means of a bracket is connected to a fixed plate fixed to the door.

There are actuators that include two levers in the design, and the second plays the role of an auxiliary one.

The third type of actuator is rack and pinion, while there are several types of it. One of these mechanisms has a fixed guide with a toothed sector along its entire length. This sector meshes with the gear of the reducer. In this design, the motor with a gearbox is movable and they are connected to the glass. That is, when turned on, the motor with a gearbox and glass begin to move relative to the rail.

Also, the design of the power windows includes a control mechanism, which is the usual buttons through which the electric motors are powered from the on-board network of the car.If, in general, we consider the device for lifting the side windows, then in the cable type with a mechanical drive there are very few components that can fail. The first of these is the cable itself. Over time, it stretches, from the effects of corrosion, its threads can break, which will lead to wedging, or it can break altogether. Excessive forces can damage the gearbox itself.But in general, such a mechanism is quite reliable, it rarely breaks down and for its maintenance it is enough to coat all its elements just once a year.

Windows of the tenth family VAZ, unfortunately, cannot boast of their reliability. Most often, if any of its elements fail, we replace the part with a new one, but in most cases the part can be repaired. Let's figure out how difficult an independent window lifter repair.

You have to resort to repairing power windows for various reasons, and most often this reason is the electric motor. Due to the fact that the engine housing is not sealed, moisture easily gets into it, and as a result, rust appears.

Hello everyone! My name is Mikhail, now I'll tell you a story about how I managed to exchange a dvenashka for a 2010 Camry. It all started with the fact that I was wildly annoyed by the breakdowns of the two, like nothing serious broke down, but the little things, damn it, so many things that really started to enrage. Here the idea was born that it was time to change the car to a foreign car. The choice fell on the tayet Camry of the tenths.

Repair of ESP VAZ of the tenth family begins with disassembling the door and dismantling the window regulator (instructions).
It is not necessary to disassemble the window regulator inside the door, it is more convenient and correct to dismantle it as a complete assembly.

1. Unscrew the fastening of the gear motor cover (key “5.5”);
2. Remove the cover;
3. Dismantle the driven gear;
4. Unscrew the screws securing the electric motor to the gearbox housing (Phillips screwdriver).

5. Disconnect the electric motor wires from the block (mark them out so as not to confuse them during assembly);

Have you had to repair windows?

I repaired the window regulator, the problem was ..

Today, the domestic “ten” continues to confidently remain in the leading positions among the most popular cars in the country. They have already ceased to be produced, but this does not prevent many people from driving a VAZ 2110.

The car is far from ideal, but it has a lot of positive qualities. One of them is the simplicity of the design, which allows you to perform a whole range of repair work with your own hands.

An example of a successful design that combines good reliability and the possibility of self-repair are power windows.

Window lifters are devices that are used to move glass on windows and hold it in a given position. Today, the VAZ 2110 is available with a fairly diverse glass lifter, which differ not only by the manufacturer, but also by the purpose.

If we take into account the purpose, then the devices can be divided into four types:

For front doors;
For rear doors;
For left doors;
For the right.

It is noteworthy that their design may be different, but they have a lot of common nuances.

Any of the listed power windows includes several main components.

They are installed on the inside of the door frame. Their function is to hold the glass sheet in a given position.

They are fixed inside the door frame in a static position.Play the role of guides for moving the glass up and down

Products made of soft rubber. They provide limitation of glass movements up and down

The design of any window regulator includes two main units - a drive and a lifting mechanism.

As in many other cars, in the case of the VAZ 2110 there are two types of drives.

Electric. A rather complex set of elements, which consists of a drum or drive gear, as well as an electric motor with a worm gear built into it. This design allows the glass to be raised and lowered at the touch of a button.
Mechanical. The most simplified design, which includes several parts, gears and handles. To raise the glass in a VAZ 2110 with a power window lifter, you need to turn the handle clockwise. The drive roller takes up the physical effort, so lifting is not difficult.

As for the lifting mechanisms, there are several of them. For the VAZ 2110, the use of various options is provided.

Mechanism type

Peculiarities

Rack and pinion lifting mechanism

It was installed on a VAZ 2107, then switched to a VAZ 2110. The advantages of such a mechanism are its simple repair and operation. But the design does not differ in increased reliability; for effective operation, the rack and pinion device must be lubricated. Design flaws forced the developers to abandon it.

A more advanced system that eliminates the possibility of glass distortion. But the reliability is not the highest. The most attractive version of the cable mechanism is galvanized metal structures. Their cost is 400 rubles. You should also pay attention to Metprom devices. Their actual price is 300 rubles. Standard VAZ cable lifts will cost 250 rubles

Lift linkage

These are the most advanced versions of mechanisms available for the VAZ 2110. Their work is based on the use of hinges. The design ensures quiet operation. However, the mechanism is only available on power windows.

Rack and cable mechanisms are offered complete with electric and mechanical drives, while lever mechanisms are available only with an electric motor.

The need to replace or repair power windows can arise for two main reasons. Namely:

Old gears of the lifting mechanism are worn out, worn out, due to which the device ceases to perform its functions;

There was a break in the cable, which was the reason for the failure of the entire system.

To solve the problems that arise, you will need to go through three or four steps:

Preparatory activities;

Dismantling;

Installation;

Repair.

If you plan to simply replace the mechanisms with new ones, then the repair stage can be skipped.Although versions with mechanical and electric windows are available for the VAZ 2110, the nuances of the replacement procedure will be identical. Therefore, the instructions below are relevant for both cases.

Lifting device diagram

Repair in most cases gives only a temporary result, so soon you will still have to perform a full replacement. This is due to the fact that each part has its own service life, degree of wear. When they are reached, the window regulator stops working.

Replacing or repairing power windows of a mechanical or electrical type cannot be called complex activities. It is quite possible to cope with such tasks with your own hands.

Power window repair process

Modern cars, the equipment of which is quite good, have an electric window regulator. Such a function is no longer considered an innovation, but it is nevertheless already appreciated by a large number of car owners due to the convenience that this system creates. But during operation, you may notice that the window regulator began to work worse, began to jam or stopped responding to your pressing a button. In order to figure out what happened to this device, you need to understand how the device works.

The power window is powered by electric motors mounted in car doors. These devices are responsible for raising and lowering the side stacks. The power window system includes the following elements:

The electric control system often has a trapezoidal design, which provides a smooth lowering and raising of the glass after pressing the corresponding button in the main switch block, which is located either near the driver, or located directly in the door card. Inside each door is a motor that operates independently. This motor works in two directions, that is, raising the glass and lowering it. The system design also includes special relays that control the electric current that goes to the lift motors.

Some machine models, along with a fuse that protects the entire circuit, also have circuit breakers that are needed for each motor. This element guarantees the correct operation of the entire lift system in the event that at least one of the motors fails.

How to detect a breakdown? The power windows can only be used when the key is inserted in the ignition switch and in the "ON" position. If you press the window up / down button and nothing happens after that, then the window regulator is broken. In order to eliminate the breakdown, you need to understand the cause of the breakdown. You need to check the system to detect a broken element like this:

1) If the windows do not work, then you need to check the auto switch or the fuse for breakage. If the likelihood is that it burned out.

2) If only the rear power windows stop working, or they respond to a signal only from the main unit, that is, the door buttons have deteriorated, then you need to check them for current conductivity.

3) In case the breakdown could not be found, inspect all the wires that connect the parts of the system for damage. If a break was found, then the integrity of the connection must be restored.

4) In the event that only one glass can be raised / lowered by the lifters using the main control unit, then try to activate the system by pressing the door buttons. If the glass has moved from its place, then check the correct operation of the main unit.

5) The windows may not work due to the fact that one of the electric motors is broken. Check the voltage on it, and also inspect the wiring. To do this, you will need to have on hand a diagram of the electrical equipment of the machine.

6) Pay attention to the guides along which the side windows move. They can be bent, that is, the glass cannot simply come out of the groove. Most often, the cause of a breakdown is faulty wiring that connects the parts of the system, or broken electric motors. The main reason for their breakdown is the frequent use of lifts, worn out wiring.

In any case, you will need car wiring diagrams. And, of course, patience, time and energy. You may need the help of a person who has already faced a similar problem and solve it yourself. An extra pair of hands never hurts.

In order to repair the window system, you first need to dismantle it. The complexity of the entire procedure is not excessive, but still work skills will not be superfluous. The window regulator is located inside the car doors, so you will need to remove their trim. For all the work, you will need the following tools:

2) Circuit breakers;

3) Multi-caliber flat and curly screwdrivers;

4) Keys of different sizes;

6) Stationery knife;

8) Hand protection gloves.

First, remove the small tweezer found in the upper corner of the door. Just the concept of it on itself along with the trim, the pinch should snap off. After removing the electrical connector, set it aside.

Take a flat-blade screwdriver and pry off the console that controls the drive for heating the exterior windows. There is an electrical connector, it must be removed and set aside. Closer to the handle, under the console, there is a screw that needs to be unscrewed.

Go down to the inner door handle. Take a flat screwdriver again, with which you need to pry the plug on the inner plane, after which you need to remove it. Then completely remove the central locking and power window control unit. To do this, pry it off from different sides without undue effort and with particular care. It shouldn't break down, but it's better to play it safe. After removal, disconnect the connector and wires, carefully inspect each contact, checking them for signs of oxidation. If they are, then everything needs to be cleaned. There are three bolts under the handle that you need to unscrew with a Phillips screwdriver. There are seven screws on the sides of the cladding, which must be unscrewed with a torx. Next, you need to remove the inner door lining by simply lifting it up and pulling it towards you. This must be done carefully, since the cable and the opening handle still have to be disconnected. At the bottom, there are still a couple of connectors - these are backlights and a signaling device that the alarm is on. They also need to be disconnected, and only after that you can completely leave the skin alone.

There is a protective membrane behind the casing, which has to be cut as it is glued onto it. But first you need to unscrew the speaker. After the membrane is sheared off, you will have 7 screws in front of you holding the trapezoid of the elevator. Unscrew them with torx. After that, you will need to disconnect the motor and the connector, after which you need to unscrew the glass. pry the latch up with a flat screwdriver. After that, the block will very easily leave the grooves. After that, unscrew a couple of nuts that hold the glass to the trapezoid. Next, put the glass on the stiffener and remove the entire trapezoid from the door.

After the mechanism is removed, it can be repaired. If the cable breaks, it must be completely replaced. There are many analogues on the market, but finding a suitable replacement is problematic. A common situation is when the length of the cable is too long. Then it will need to be shortened. But during operation it will stretch, so be prepared for the cable to have to be shortened again. Therefore, it is better to give preference to the original.

The cause of the breakdown may be in the worn out rollers or in the guides. In this case, they need to be replaced, although it is very difficult to find them. Therefore, car owners often order the entire trapezoid as a whole.

After repairs, the entire power window system must be reassembled in the reverse order. Experts advise to check whether the system is working before assembly. To do this, connect all electronics and turn on the lift.If all is well, then you can reassemble the entire skin. As you can see, everything is not so difficult. The main thing is confidence in the success of the business.
