wiper VAZ 2110

A windshield wiper or wipers have an important function on a vehicle. When they fail, any driver begins to feel uncomfortable, especially if he is on the road.
Repair of wipers in this case will not present any problems, especially if you use the information given in this article.

The essence of how to repair wipers on a VAZ 2110 is to fix the levers or deformed wiper rods. Often the reason lies in the contamination of the parts.
If it is impossible to repair the wipers, then they must be completely replaced.Often the cause of a breakdown can be a gearmotor, and if you replace the gears in it, clean the contacts of the collector or limit switch, everything will work.
If the gearmotor cannot be repaired, it will have to be replaced with a new one.

All the work must be done in order and at the same time not missing anything:

remove the wiper (on the vaz 2110 it can be completely removed);
unscrew the nut securing the leash;
remove the leash itself.

removing the leash from the wiper

Go ahead and continue to repair the wipers of the VAZ 2110:

the turn of the gear motor has come (it can be wrapped in a thin leather film, which must be removed);
unscrew the three bolts of the gear motor, marked with arrows in the upper photo;
remove the black plastic cover by unscrewing two screws for this;
after removing the cover, unscrew the following screws.

We continue and by the way, you can also repair the wipers on the VAZ 2107:

Video (click to play).

take out the plate with 3 contacts located on it;
after which we remove the brown gasket;
we see the design of gears and rollers;
remove the largest gear along with the roller, revealing a plastic washer under it;
we extract two small gears, which must be noted before removal (this is done in order not to confuse their original location, because they do not have the same inclination of the teeth).

removing the gears of the wiper motor VAZ 2110

we disconnect the gearbox from the electric motor by unscrewing for this two screws located opposite;
we remove the anchor from the metal case of the electric motor;
at this stage, you should thoroughly clean all parts from dirt and old grease (we use a rag soaked in acetone).

Cleaning the wipers of the VAZ 2107, the repair of which can also be carried out according to this scheme, implies care and a detailed inspection:

we press with our fingers on three brushes in special holders (they must move freely, and if they go down tightly, then there are defects or cracks, and they must be replaced completely);
we check three springs, which should be even, without stretching and breakage.

We continue to repair the wipers of the VAZ 2107 or 2110 by inspecting the collector.
For this:

we inspect it for damage, scratches or dirt;
if it is heavily soiled, it is recommended to use a fine sandpaper (if this does not give any results or it will already be seen that the collector is badly worn out, it will be necessary to replace the whole armature or the entire gearmotor as a whole);
we inspect the teeth of the gears of the gearbox and replace them if gross scratches or other defects are found;
if defects are found on the thread of the rollers of the levers or brushes, then the rods must be replaced in a complete set;
we inspect the limit switch plate and, if necessary, run it with a sandpaper and over it;
we inspect the leash mount, or rather its black rubberized cushions (if they have lost their elasticity or burst, you need to replace them with new ones - replacement is carried out by removing the inner spacer steel sleeve);

On the VAZ 2109, the repair of the wipers also takes place, that is, they start with the gear motor.
So, let's continue:

we assemble the wiper, having previously well lubricated all the parts (especially you should pay attention to the gross worm of the armature and gears - use Litol-24 grease, and the marked gears should be put in place exactly);
set the anchor by tying the brushes with wire to the contacts (this stage of work is carried out in order not to curl the brushes and therefore they must be folded);
we mount the anchor in the gearbox housing very carefully;
we install the electric motor housing on the gearbox, holding the armature shaft;
we untie or bite off the wire holding the brushes and knock on the gearmotor with a wooden hammer in order to center the bearings;
we install the leash back on the axle, which must necessarily stand in a horizontal position and in proportion to the central thrust.

Attention: Before proceeding with the repair of the gearmotor, read the technical characteristics of the normal operation of this part.

shaft rotation frequency, if voltage is applied to 14 V low - thirty or forty;
the rotation speed of the shaft of a larger value - seventy;
current consumption at first speed - 3.5 A;
at second speed - 5 A.

On the VAZ 2106, the repair of wipers is carried out a little differently. Although the whole process is similar to the above instructions, there is still a difference. But consider a way to change the old wiper blade to a new one.

First, we arm ourselves with a screwdriver and start the process:

for VAZ 2106, the wiper drive rods are connected not only to each other, but also to the cranks with hinges;
remove the wiper and motor reducer;
remove the thrust hinge stopper from the groove of the crank axis;
remove it from the axis.

removing the hinge stopper from the axis

remove the thrust from the axle;
disassemble the wiper rods;
we assemble a new thrust in the reverse order with the same drive;
install the gearmotor on the bracket carefully, paying attention to the condition of the rubber bushings.

Attention: When working, you need to use a wide-blade screwdriver. It will be more convenient for her to remove and install the bushings.

The repair of the VAZ 2106 wipers continues. Now let's look at how to clean the manifold and change the gears.
We carry out the following operations:

we remove the wipers, as indicated above;
we turn off the fasteners for fixing the leash;
remove it from the gear motor roller.

This video can be found on the internet.
We continue:

we unscrew the gearbox mounting bolts (there should be three of them);
remove the gear motor;
we see a protective film on it, which should be removed;
remove the plastic cover by unscrewing the two fastening screws;

This photo shows how this is done:

removing the cover from the gear motor VAZ 2106

under the lid we see two more screws, which we also unscrew;
remove the panel with the contacts of the limit switch;
we remove the gasket with our own hands;
we see gears;
remove the largest of them together with a roller and a plastic washer;
after that, we remove the other gears (as mentioned above, they will need to be marked so that they do not mix up during assembly);
remove the gearbox from the electric motor by unscrewing the two fixing screws;
we begin a thorough inspection and clean all the parts from dirt and old grease;
the brushes in the brush holder should move freely down and up (pay careful attention to this, they should not jam / if we find such a problem, then we change the gear motor assembly or brushes and do not forget to solder them to the brush holder when replacing them);
according to the instructions, the springs should also be inspected without fail (their elasticity should be checked and if we notice increased extensibility or another defect, we replace them with new ones);
we clean the collector with sandpaper, if scratches or traces of dirt are visible on it (if it is too worn out, then we replace the anchor or the gearmotor as a whole);
we also change gears if we notice worn teeth on them;
collect everything in reverse order.

The tips given above will help the car enthusiast save good money on repairs, because the price for it today in car services is quite high.

The windshield wipers of the VAZ-2110 car themselves do not represent anything constructively complex. However, their failure, especially during heavy rainfall, can provoke an emergency. One of the main elements of wipers or "brushes" is a trapezoid.

The trapezes are somewhere here!The wiper trapeze is a special unit that converts the engine impulse into the forward motion of the wipers.Simply put, it is she who is responsible for their movement on the windshield or rear window of the car. Since weather conditions are often unpredictable and the windshield must provide full visibility, breakage of this part must be promptly identified and repaired.Most often, plastic bushings wear out in the trapezoid.Although, at first glance, it seems that the movement of the brushes occurs directly, in fact, the trapezium, which is an electromechanical unit, is responsible for it. It works according to the following principle:

The wiper motor uses a finger, which drives the trapezoid itself.

Due to the connection of the gearbox and the shafts, oscillatory movements occur, forcing the brushes to move over the glass, cleaning it.

It often happens that the trapezoid fails. This happens especially often after or during the winter season. Some inexperienced owners of the VAZ-2110 turn on the "brushes" without bothering to clear the glass from snow... Often the "wipers" freeze to the glass, and an attempt to move them from their place ends in breakage. To prevent this from happening, you need always check the brushes for freezing before switching on in winter .Kirdyk is a slang word meaning an extremely bad situation.It happens that the bushing retaining ring breaks and the thrust simply flies out.The slightest disturbance in the trapezium operation can lead to incorrect operation of the "wipers". Usually this part is changed to a new one, although in some cases it is possible to get by with the installation of a repair kit. Its cost is significantly lower than the price of the entire part, although the repair time will take much longer. Here is a list of the main signs by which you can determine that a part will soon fail:

Windshield wipers begin to do poorly with their direct job. This is due to the release of pressure.

An unusual noise is heard during operation.

A backlash appears, which can be determined even visually, since the glass will be difficult to clean.

It so happens that the brushes go easily in one direction, and with difficulty in the opposite direction, constantly slowing down.

All these problems lead to the fact that the windshield remains dirty, with streaks and smudges.

Therefore, it is better to remove the old part and go with it to the auto parts store. They are not only attached in different ways, but also differ in connectors through which they are connected to the motor. If you can't find an old-style trapezoid, and you have just one, you will have to redo the system or look for a used part.

If the wiper motor is working properly, you can only change the trapezoid itself.

The easiest way to get rid of problems with VAZ-2110 windshield wipers is to contact a service station. There, the trapezoid will be replaced in an hour or an hour and a half. But if unscrupulous craftsmen notice that the owner does not understand the cause of the breakdown at all, they can repair the car for half a day, saying that the problem is very serious.

When driving in adverse weather conditions, timely cleaning of the windshield is of great importance, and often the question arises of how to check the wiper motor. The main purpose of the unit is to rid the car's wind aperture of moisture, snow and other atmospheric precipitation, so we will figure out how to maintain this mechanism in working order.

Modern cars are equipped with two windscreen wipers, which have a double design for the front glass (there are two rubber bands on the wiper for more efficient operation), and for the rear one - a single version. Most windscreen wipers operate in three main modes. These modes are intermittent, slow and fast.

The windshield wiper includes in its design an electric motor with a gearbox, a system of levers, brushes and a mechanism that automatically returns the car wipers to their original position. Simultaneously with the wiper, the windshield washer is operated. When this small but important mechanism stops working, do not hesitate to fix it, because the weather is rarely predictable.

There may be several reasons why the wiper does not work, consider the frequently encountered situations below. First of all, there may be no contact between the collector and the brushes. If, after disassembling the electric motor and stripping the contacts, the malfunction has not been eliminated, then in this case, most likely, the wiper motor needs to be repaired, but there are several more options that should be checked before drastic measures.

In the event that the levers are jammed or the gearbox is seized, a bimetallic fuse may be triggered. Then your system will also not respond to attempts to turn it on. Naturally, correcting the position of these components and replacing the fuse, you can solve this problem. The wiper should work normally after the fault has been rectified.

Sometimes this mechanism only starts functioning at one speed. In this case, the switch or resistor is most likely faulty. The brushes may not be installed in the lower position, for this it is necessary to adjust the stop mechanism. Often there are situations when, when you turn on the wiper, there are extraneous sounds in the form of a creak or rattle. If this is not due to the dryness of the glass or the presence of sand brushes under the rubber bands, then, apparently, something is junk inside, so it's time to look deeper.

The structure of the wiper is not complicated. The fingers are attached to the levers of the brushes, which may be the very first suspected sources of extraneous sounds. As a rule, they sour in the bushings of the bracket due to violations of protection, when water and dirt gets inside. If the device passed this check too, and the sound persists, then repair or replacement of the wiper motor is necessary.

In order to remove the motor, you need to de-energize the electrical system, and only after that it can be dismantled.

Sometimes the rear wiper motor, as well as the front wiper motor, simply fails. It is unlikely that this will be a frequent breakdown, but if it catches you, nothing can be done, you will have to figure it out. In order to repair the device, it must be removed, and this is a rather laborious process.For example, the classic VAZovsky models, most fully demonstrating the entire technical process. So, the removal of the motor takes place in several stages:

The nuts that secure the brush arms are unscrewed, after which they can be removed from the tapered splines of the drive. If this is difficult, penetrating grease may be applied to the splines..

The brush arm drives are dismantled by unscrewing the fastening nuts, and then the plastic bushings and rubber gaskets are removed.

The terminal block in the harness is disconnected and removed by lifting the edge of the seal through the slot in the bulkhead of the engine compartment.

The next step is the direct removal of the wiper. Then the washer and the spring clip are unscrewed from it, the thrust is disconnected.

After unscrewing the three mounting bolts, you can get the motor.

After visual inspection, all defective parts should be replaced. If restoration is not possible, then a new motor should be purchased. The assembly of the entire glass cleaning system is carried out in the reverse order.

When you need to replace the wiper trapezoid

How is the repair of the wiper trapezium

Today, no one can be surprised by the presence of their own car in the family. Manufacturers are trying to make their "product" as safe as possible, and this applies not only to the engine and components that provide movement. The safety issue sometimes directly depends on the cleanliness of the glasses. If the windshield and rear windows are not clean enough, covered with drops of water or snow, then you will strain your eyes more and more to fully see the situation on the road. After an hour of driving like this, your concentration will drop, and this could lead to an accident. How to make sure that nothing terrible happens? The correct answer is to monitor the condition of the wipers, in particular, the trapezoid. We will talk about it.

The most important element of the wiper system is the trapezoid. It is this element that is responsible for converting the rotational movement from the electric drive shaft into the translational movement of the wipers. If the trapezoid works correctly, then the safety of your movement in bad weather conditions will be ensured. The design of the wiper is quite simple, but reliable and durable. The main elements of the system are:

In order for the wiper blade to move smoothly on the glass of the car, sufficient force must be transmitted to the leash. This is achieved due to the operation of an electric motor, which, in turn, is connected to a gearbox, which has a worm gear. Since there is a gearbox in the system, it is possible to reduce the speed of the shaft and increase the amount of force that is transmitted to the trapezoid. The wiper trapeze is responsible for converting the rotational motion of the electric motor into the reciprocating motion of the wiper arms. The trapezoid makes it so that the movements of both brushes are synchronized, and the quality of work is at its best.

The device of the trapezium wipers on cars from different manufacturers is almost the same. The difference can only be in the dimensions and shape of its various parts. The main elements that create this node are:

With the help of calculations, designers determine what the profile of the trapezoid links should be. Thanks to this, the required safety margin is formed in the structure, that is, the integrity of the system is preserved when the brushes are moving. In order to minimize losses due to friction, and to make the energy consumption of the electric drive optimal, the connecting elements of the trapezium are made of a material based on polyformaldehyde. It produces an extremely low coefficient of friction and is characterized by a high level of wear resistance. To protect metal elements from corrosion, they are covered with a galvanized layer.

The incorrect operation of the wiper trapezium, as well as the presence of damage on it, is indicated by malfunctions in the work of the wipers themselves. For example, they can move too slowly regardless of the operating mode, stop spontaneously when cleaning the windshield and rear windows. Another vivid confirmation that the wipers are faulty are the intermittent movements of the brushes, jumps, the characteristic sound from the leash during operation. The main reason for such malfunctions is the presence of oxide on the drive leads in the trapezoid bushings.

It is the oxide that prevents the wipers from rotating normally. If this problem is ignored, then the electric motor can also break down, on which a significant load is placed, and this entails the likelihood of burnout of the electric motor armature. If there is a backlash in the wiper leashes, that is, the leash beats against the hood, then rest assured that the trapezium bushings are worn out.

If you notice even a hint that the wipers are not working correctly, then diagnose the system as soon as possible, and, if necessary, repair or replace the broken unit. Otherwise, the risk of getting into an accident on the road increases greatly. The need to pay attention to the trapezoid of the wiper may be indicated by the low pressure in the system. If the wipers do not completely remove the snow or water, then there is a problem with the pressure.

In order to understand what exactly needs to be done with the trapezoid - change or repair - it is necessary to carry out diagnostics. If you decide to replace the trapezoid, then the new mechanism must be selected correctly. Two trapezoids from different manufacturers can be very similar in appearance, but they are attached in different ways. The sizes of the leashes and the types of connectors for connecting to an electric motor can be different. The conclusion from all this is simple - buy a trapezoid from the original manufacturer specifically for your car model.

You, of course, can go to the service center, where in just a few minutes they will tell you that the disturbances in the work of the wipers are connected with the trapezoid. Replacing with the hands of a master costs money, and given the fact that this simple work can be done on your own, you will save a decent amount.

First you need to remove the old trapezoid using the key "12". Unscrew the nuts that secure the wipers, then remove the brushes themselves. You need to be careful at this stage, as the spring is elastic, because of which you may encounter some problems. To make the process easier, bend the leashes ahead of time. After that, unscrew the screws with a Phillips screwdriver and remove the plastic part. Pry the plugs with a knife, remove them and remove the remaining fasteners.

In order to access the trapezoid itself, remove the plastic parts of the casing. There is a connection between the part itself and the electric motor, do not forget about it. Remove the nuts and screw that connect the trapezoid, electric motor and body bracket. Be sure to disconnect the power supply! Remove the motor, remove all fasteners of the trapezoid and take it out.

When you buy a new trapezoid, it will be disassembled, that is, you need to assemble this constructor before installation. Everything is done with three bolted connections. Insert the first component into the tab near the casing. This will require strength, but you do not need to tighten everything at once with the bolt. Next, put on the part of the knot that remains. Be sure to adjust its position.

After that, you can tighten all the nuts and go to the installation itself. The entire structure needs to be assembled in the reverse order, but be aware that you will have to spend time adjusting the brushes. Do not forget to lubricate all units and rubbing surfaces with special graphite grease. Experts recommend not to use lithol, as it loses its properties at low temperatures.

If the wipers do not work, for example, due to a worn bushing, then the whole trapezoid can not be changed; repairs will be enough. That is, it all depends on the diagnostic results. There is one very important recommendation to keep in mind. If you are an inexperienced person in terms of repairing windshield wipers, then in no case unscrew the armature shaft adjustment screw. Otherwise, the axial clearance of the shaft will be violated.

1) Using a wrench, unscrew the nut that holds the trapezoid crank;

2) Pry the crank with a screwdriver and remove it;

3) Using a wrench, unscrew the 3 bolts that hold the gearmotor to the bracket;

4) Unscrew a pair of screws that connect the wires and the fuse, then disconnect the wires;

5) Remove the gearmotor very carefully from the bracket;

6) Remove the retaining ring from the gearbox shaft by simply prying it off with a screwdriver. There are shims behind the retaining ring, which must also be removed. To ensure that the reassembly is accurate and correct, mark the washers so that they can be returned to their places later;

7) Remove the cover that is held on the gearbox with three screws;

8) The gearbox panel will be located under the cover, it also needs to be dismantled;

9) Remove the gear from the reducer by turning the first one a little;

10) Remove the pair of screws that secure the gearbox housing, with the second screw on the other side of the gearbox;

11) Take out two small plates from the body of the electric motor;

12) Disconnect the housings of the electric motor and gearbox;

13) Remove the armature from the motor housing, then blow out the motor housing with compressed air, this will help remove even the smallest particles of coal dust from the inside of the housing;

14) Return to the trapezoid by removing both retaining rings from it;

15) Disconnect the rod and the wiper blade bracket, then remove the adjusting washers from both rollers;

16) Return to the gearbox housing, there are brush holders on it, from which you will need to get the brush springs. If the springs are damaged, then they must be replaced;

17) Press down on the brushes in the brush holder, they should move easily, should not bite, if they are worn out or covered with debris - replace;

18) Take the anchor of the case, determine the degree of contamination of its collector, if necessary, clean it with fine-grained sandpaper. If the manifold is badly burnt, install a new anchor;

19) Check the gear wheel: if it is worn out or damaged, install a new element;

20) Inspect the rods, if they are deformed, try to bring them back to their original state, otherwise - replace;

21) If the splines and threads of both rollers are damaged, replace the complete rods;

22) Inspect the contacts of the self-stop mechanism: if they are oxidized or burnt, then clean them with fine grain sandpaper;

23) Replace the rubber elements with new ones.

If it is snowing or raining outside, windshield wipers become indispensable elements of the car.

Elements of wipers for VAZ 2110

In our material, we will talk about the mechanism of the VAZ 2110 wipers, discuss the main reasons for their malfunction, the issue of repair and the search for alternatives to standard wipers.

First, let's try to understand how the wipers on the VAZ 2110 are arranged and what components form a one-piece unit called a wiper.

At some point, the car owner may notice that his wipers are not working. This can manifest itself in their complete stop or work with a creak.

First of all, look for the cause in the electric motor. But remember that there are also mechanical problems.

The most popular mechanical wipers failures:

When the cleaners are turned on, the sound of the motor can be heard, but the brushes do not move or twitch slightly. Probably, the crank nut to the gearbox axle lost its grip or was completely unscrewed.
Asynchronous operation of the wipers indicates a problem with the leash. Again, check the lock nut. When tightening the nut, do not forget to put the brushes in the correct position.

As for the problems with the electrical component, they manifest themselves as follows:

The janitor moves very slowly, stops, then starts working again, does not stubbornly go to the lower position. Check the limit switch. By bending the contacts, it is adjusted in this way. If such a measure has not borne fruit, replace the entire VAZ 2110 wiper motor assembly, since the gearbox is built-in;
You have switched on intermittent operation, but the brushes are running non-stop. Here the problem lies in the relay, which must be replaced. If, when you turn on the device, you do not hear the sound from the rotation of the motor armature, then the relay is 100% to blame. If not, then check for burning and oxidation on the contacts;
When choosing any mode, only the clicking of the thermal fuse is heard. In this case, the anchor and brushes are in place. Check if the brushes are frozen because of the frost, so they do not move. Either fuse F5 has blown, or the anchor has burned out;
The electric motor does not turn on, although the fuses are OK. Check the quality of your contacts. This is often the cause of a hanging brush or a burnt out anchor.

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least elementary experience in working with a car and its electrical component. Image - DIY vase wipers repair

Unscrew the fixing nut

First, let's figure out how to remove the wipers on the VAZ 2110. The design provides for several fasteners, by unscrewing which, you can easily remove the brushes themselves.

But with the disassembly of the wiper assembly, everything is a little more complicated. It is disassembled as follows.

Remove the dashboard.
On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
Next, check the condition of the fuse, which is responsible for the operation of the wiper drive.
Disassemble the steering column to inspect the switch status. If it has damaged insulation or other damage, replace the unit.
Unscrew the electric motor from the body, test it in action. If the breakdown is not serious, it can be repaired. It is better to just replace it together with the relay.
Check the drive. It is not uncommon for a pulley to break on it, because of which the device has to be changed to a new one.
Make sure the trapezoid is working properly. It may be necessary to replace the trapezoid of the wipers with a VAZ 2110, if during the operation of the car the lubrication of the device has deteriorated, all kinds of debris and water have got there. If the lubrication does not work properly, the plastic bushings of the hinges will wear out, hence backlash will arise and the resistance will increase during the operation of the device. The very same trapezium serves to transfer the force from the electric motor to the wiper arms.

Most of the car owners of the domestic “ten” are used to changing worn-out and out-of-order windshield wipers for similar ones.This often happens because they do not see alternatives, are not familiar with them.But this size can be increased to 530 mm ... It is not recommended to put it anymore, because this way the wiper will not be able to work efficiently, and the drive will simply not be able to cope with the load. As a result, too long brushes cause creaking and jerky work. Plus, do not count on the long service life of the wiper mechanisms.Native windshield wipers for the "dozen" are pretty good. But there are more expensive, but also more highly efficient, quality devices.
