Car air conditioning plays an important role in ensuring the comfort of a Ford Focus 2. This is especially true in summer, when the temperature outside rises high enough and the car air conditioning system comes to the rescue, which ensures the optimal temperature level in the passenger compartment.

In addition to creating a comfortable microclimate, the air conditioner is also responsible for the function of cleaning the air from odors and moisture.

The second generation Ford Focus air conditioner is a modern device consisting of many components and assemblies. The main parts of which it consists are a pressure reducing valve, a pressure valve, a throttle pipe, a receiver, a coupling, a heat exchanger, a radiator and a compressor.

The air conditioner compressor Ford Focus 2 is the most important part of the air conditioning system in a car, since it contains the main functions that ensure the normal functioning of the entire system. In addition, the breakdown of this particular part is the most critical, since its replacement is an expensive undertaking, and repair requires special knowledge and equipment, which is available only in specialized car services.

However, if there are malfunctions in the operation of the air conditioner or compressor, in particular, then it is necessary to solve them promptly, for this you need to know what signs in the operation of the air conditioner may indicate the presence of problems.

The main signs that the air conditioner compressor needs repair:

• noise that wears out details and depending on the severity of the problem, it can be louder or quieter and can be heard both when the air conditioner is running and when it is off;
• play between the gaskets on the hoses or at the shaft seal;
• leaking freon from certain places in the air conditioning system.

If you notice any of the signs of a malfunction in the air conditioning system, do not postpone a visit to the car service, since over time these malfunctions will only become more critical and difficult to repair, and therefore more financially costly.

To avoid the problems described above, you need to understand the reasons for their occurrence.

The causes of problems in the operation of the air conditioning compressor are as follows:

There are many more problems due to which the air conditioner compressor on FF2 can fail. Most often this happens after prolonged cold weather, so pay special attention during this period to the operation of the air conditioner and do not neglect a visit to a car service for diagnostics. Thus, you can save a significant amount of money and time in the future with stable operation of the air conditioning system of your car.

The presence of such malfunctions

parts of an air conditioner, like a compressor, disable the entire air conditioning system, which is especially unpleasant in the summer, when the need for a car air conditioner is most urgent, because it depends on how comfortable the stay in the car will be for the driver and his passengers. In case of failure of the air conditioning system, you should immediately contact the car service for repair work. Depending on the level of malfunctions, specialists will repair or replace the compressor. In any case, this procedure is preceded by system diagnostics, which is designed to identify the problem and the source of its origin. The repair procedure itself is complicated not only by the presence of a large number of parts in the system, but also by the fact that the coolant contained in the air conditioner has toxic properties and any actions must be carried out extremely carefully and with all precautions.

When providing repair work, the foremen will dismantle the air conditioner and disassemble the compressor. This is done according to the following algorithm:

• freon is released from the air conditioner;
• then the central bolt is unscrewed and the upper part of the compressor is removed;
• using a special press, the coupling is dismantled after removing the retaining ring and bearing;
• then the bearing seat is lubricated with oil and a new part is installed.

Replacement of certain parts

depends on the nature of the problem. After the specialists make repairs, flush the system and replace the necessary parts, the compressor is assembled in the reverse order.

After the steps described above, specialists will refuel the air conditioner.Before this, the process of evacuation takes place, which consists in removing all moisture and air from the air conditioning system using a special pump. If you do not perform this action, the air conditioner and its individual parts will soon corrode. When filling the air conditioner, oil is often added to the freon.

If it becomes necessary to carry out repair or diagnostic work, contact only proven car services. In our service we carry out work on the repair of all types of air conditioners, including for cars of the Ford Focus 2. Our specialists will serve your car quickly and efficiently!

As a result of external influences or poor-quality repairs, the tube of the car's air conditioner may be damaged. If the element is damaged, depressurization occurs and the system simply stops working. How to remove the tube of the Ford Focus 2 air conditioner and how to replace or repair it yourself, we will analyze in this article.

The pipeline of the car air conditioner performs an important function - freon circulates through it, ensuring the operation of the air conditioning system. It is located under the hood, and due to the fact that all the elements of the Focus engine compartment fit tightly enough to each other, there is a risk of damaging the air conditioner tube when repairing nearby nodes.

Also, a long service life of the car or an accident, as a result of which the rubber body of the tube burst, can become the cause of element breakdown.

In any case, the damaged tube must be replaced, so read on for a step-by-step guide on how to do this.

• Place the machine on a lift.
• Unscrew headlight and remove engine underbody guard.
• To remove the tube attachment, you will need keys for 10 and 13.
• Remove the air conditioner pipe Ford Focus 2.

After removing the part, install a new tube and replace the removed parts.

• Important! After replacing a burst air conditioner tube, be sure to flush and evacuate the system, otherwise the compressor will fail!

Spare parts for Focus cannot be called cheap, so you always want to save as much as possible. One option is to repair the damaged element - in this case, the air conditioner tube. Consider three ways to repair and breakdowns in which these methods are suitable.

• We eliminate small cracks and microdamages in the pipeline - for this it is necessary to use an aerosol repair compound. It is enough to remove the damaged tube, find and cover the damaged areas with the composition, and then let the composition dry for 12 hours. Mannol Epoxy-Metal 9905 will do.
• Small cracks can also be sealed with self-sealing rubber tape. Mannol MULTITAPE 9917 will do.
• More noticeable damage - argon arc welding is used. It is suitable for those who have the skills to work with a welding machine (or friends with the necessary skill).

For Ford Focus 2, breakage of the air conditioner tube is considered a fairly common phenomenon, so it is very useful to know how to remove and replace the tube yourself. Changing a pipe to a new one or repairing an old part is the business of every car owner. We recommend not to risk it and, if there is no extra money to buy an original high-pressure pipe, install a cheaper analogue.

If problems have begun, now I will try to describe how to find where the trouble lies. Go:

Now I will try to briefly describe the problems that you can fix yourself:

For the stable operation of the system, it is first of all necessary to keep the radiators clean. If the condenser starts to work poorly, the first thing to do is to clean the radiators.
For a long compressor life, many experts advise making a complete oil change every 3-5 years (the refueling device changes only 20% of the oil).

For the air conditioner to operate, a certain pressure must be maintained in the system. If the compressor is turned on when the pressure is low, then the compressor may break down (freon also contains oil for lubricating the compressor), if the pressure is too high, then something may not withstand and it will also be bad. Controls the activation of the ECU compressor. There are 2 sensors to monitor the pressure in the system: a sensor for too low and too high pressure. These sensors will prevent the compressor from starting and save the system from self-destruction.
The low pressure sensor can block the activation of the compressor if there is not enough freon and the temperature overboard is not high (if less than +4, then the condender will not start at all) -> then you need to go to refuel.
The high pressure sensor will protect the system when the system is charged with freon above normal and will turn off the compressor when the system overheats due to a clogged radiator.
Location of sensors
The low pressure sensor is just a switch and should be closed at normal pressure
The high pressure sensor is more complex: it converts the pressure into a voltage level at the signal contact. Its check and voltage levels are described here

If with sensors, ambient temperature (if it is less than +4 - do not start) and engine temperature (do not start when overheating), then the ECU gives a control signal to relay R11 (marked with an arrow in the figure), which should work and supply voltage through fuse 27 on the compressor clutch.

The connector for the coupling is made removable because of this, it oxidizes over time and the compressor starts to work every other time. If the air conditioner relay is triggered and 12V comes to the air conditioner connector, then 90% percent, that the problem is in the connector - we restore the clutch connector

PS who has something to add - write to the LAN: add.

The comfort of the second generation Ford Focus car depends on many factors, including the condition of the suspension, the correct operation of the engine, etc. In the summer, air conditioning is of particular importance, since at high temperatures outside, it allows you to create a pleasant microclimate in the Ford Focus 2. If it breaks down, there can be no talk of any comfort, since it is no longer possible to cool the air. In our article, we will tell you what are the main reasons for the breakdown of an air conditioner, how to properly carry out repairs and what may be needed for this.

Air conditioner repairs are usually carried out in a separate direction. The fact is that the process itself is simple, but due to the toxicity of the coolant, if improperly handled, you can get poisoning. Therefore, if you service the air conditioner on Ford Focus 2 yourself, always take all safety measures. The air conditioner on the Ford Focus 2 has a modern design and consists of the following parts:

• A compressor that creates high pressure for the refrigerant.
• Pressure reducing valve.
• Throttle pipe.
• Clutch.
• A radiator that helps to quickly cool the air in the passenger compartment.
• Heat exchanger.
• High and low pressure valve.
• Receiver.

In general, the air conditioner on the Ford Focus 2 can fail quite often and, as a rule, this happens after winter. There are two main reasons for system breakdown:

• Violation of the tightness of the system and the lack of the required pressure.
• Problems with electronics, which consist in an open circuit.

It should be noted that first of all, the tightness of the system is checked, because if it is violated, the air conditioner on the Ford Focus 2 will not turn on. To do this, you need to open the hood and push the pipe nipple. If there is a weak gas flow from there, then this is the problem. However, do not rush to prime the system, as you need to determine the location of the leak. To do this, you need to inspect the radiator, various pipes and connections.If you find damp places, loose fasteners, you must immediately eliminate the malfunction. The problem is that there is oil inside the air conditioner and due to prolonged downtime and lack of lubrication, rubber parts begin to burst and collapse, and this leads to a violation of the seal.

You can do a similar check yourself, or you can ask for help at a service station. The second option will be much faster and easier, but you will have to pay.

A breakdown of the air conditioner can also be caused by a breakdown in the electrical circuit. For example, if the pressure sensor is not working, then the clutch will not function. Quite often the freon sensor fails. By the way, in some situations the fuse may blow, and therefore do not forget to check it too.

It may be that the air conditioner on the Ford Focus 2 works, but cools very weakly. This indicates a dirty cabin filter or a problem in the fans. In any of these situations, repairs are needed, which can be done by yourself or at a service station.

To fix a malfunction in the air conditioner, it will most likely have to be removed and disassembled. This is not very difficult to do, but it requires extreme caution. As a rule, detailed instructions describing all the work for a Ford Focus 2 car can be easily found on the Internet, and we will present you with a short algorithm that will allow you to understand the principle of operation. So, repairing an air conditioner requires removing and disassembling its compressor. To do this, you need to do the following:

• We release freon from the system using a screwdriver and a rag, after which we finish removing the compressor.
• Unscrew the central bolt and dismantle the upper part of the compressor.
• We remove the retaining ring, after which a clutch will appear, which will also need to be dismantled.
• We remove the bearing. If you can't unscrew it, then you can cut it off.
• The clutch cannot be removed just like that, and therefore we press it out using a special device.
• We dismantle the bearing, lubricate its seat with oil and install a new part.

That's it, the air conditioner compressor has been disassembled. Depending on what kind of malfunction is present in the Ford Focus, certain parts need to be changed. Such repairs can be done independently, but for beginners it is better to do everything under the guidance of experienced motorists. After the repair is over, all parts are cleaned and replaced if necessary, the compressor will need to be reassembled in reverse order. It should be noted that it can be difficult to install the A / C belt, but do not be afraid to use force. Also, if you find any minor malfunctions (burst rubber bands, seals) during the repair of the Ford Focus 2, fix them.

As you already understood, repairing an air conditioner is not the easiest thing. The main thing is to correctly find out the cause of the malfunction and eliminate it as soon as possible. Nowadays, all conditions have been created for comfortable movement, and therefore, in order for the second generation Ford Focus 2 to bring maximum pleasure, take proper care of it and repair it in time. Good luck!

It's no secret that the operation of the climate system largely determines the comfort for the driver while driving, especially in the hot season. In particular, we are talking about Ford cars. If the unit does not turn on, the compressor, evaporator, condenser or other elements of the Ford Focus 2 air conditioner may be to blame for this. We will discuss the problems of an inoperative condenser below.

If a working air conditioner stops turning on or does not work correctly, it is not necessary to refuel it immediately, as many motorists say. Of course, refueling the air conditioner is an important procedure that should be carried out from time to time, but it does not always solve the problem.

If the air conditioning system does not activate when it is turned on, it is usually the electrical part of the vehicle that is causing the problem. Also, the malfunction may lie in the electrical components of the system.

The following are the main reasons to consider if the system will not turn on:

Why the system does not produce enough cooled air flow:

It happens that diagnostics show the need to replace the air conditioner radiator. It is possible to identify the location of the leak by using a refrigerant with a special ultraviolet additive. The machine must be operated for several days on such freon, of course, with the air conditioner on, after which it is re-diagnosed using an ultraviolet lamp. For more information on how to replace the air conditioner belt Ford Focus 2 or on another car, how to check the air conditioner belt, the air conditioner compressor bearing and other components, read here (video author - Automation - auto air conditioners from A to Z).

The installation may not function not only due to breakdowns, but also improper operation, as well as the refueling procedure. If incompetent masters are engaged in filling the system, such an outcome is quite possible. When refueling a device with freon, it is always necessary to take into account the model and make of the car, since there are certain standards and requirements for Ford in terms of refueling. The same goes for butter. If too much oil is used, the efficiency of the system will be significantly reduced. When buying oil and freon for the system, do not try to save money, as this can lead to more serious costs in the future.

Repair of the air conditioner compressor and other elements, replacement of the bearing, replacement of the air conditioner tube should always be carried out by professionals. Having saved once, you can seriously regret it later. Do not forget about proper operation - at least once a month during off-season (winter) turn on the air conditioner for 10 minutes.

A step-by-step instruction for this process is presented in the video below (the author of the video is ABC Ford).

Failure of the compressor and air conditioning in general on Ford Focus 1, 2 and 3: how to repair and maintain the installation?

Thanks to the air conditioning system, the driver of the vehicle is able to drive more comfortably. But since not a single unit in a car can work forever, sooner or later motorists are faced with the need to repair the conder. How to understand that the air conditioner compressor Ford Focus 2 or any other unit of this system is out of order, how to repair it yourself? Look for the answers below.

What to do if it cools poorly or does not cool the condenser at all, what malfunctions are characteristic of the air conditioning system and how to clean and refuel the condender?

First, let's take a look at the structure of the system:

There are two conditions in which repair of the air conditioning system is required - the condender does not work at all and does not turn on or turns on, but does not cool the air enough.

If the system does not start, then the reasons may be as follows:

If you are faced with the problem of insufficient air cooling in the passenger compartment, then to troubleshoot you need to proceed as follows:

Over time, the air conditioner of a Ford Focus car may work less efficiently due to contamination, therefore, before refueling the system, you need to clean it. In order for the Conder to work correctly, it must be refueled once every 2-3 years. Before filling the system, you need to make sure that there is freon in it, while the liquid level must correspond to the norm. Otherwise, it is necessary to get rid of the cause of the leak or depressurization.

Conder filling scheme looks like this:

Most of the malfunctions in the air conditioning system can be corrected by yourself.But to check individual components, such as a radiator, specialized equipment may be required, which can only be found at a service station. Before buying freon, study the service book - it must clearly indicate the brand of refrigerant that can be used... Also, do not forget about the maintenance of the air conditioner - every 2-3 years, change the oil in it and the desiccant with flushing the system, and then the air conditioner will work for a long time.

How to properly clean the air conditioning system in a Ford Focus 3 car - learn from the video (video posted by user Kirill Korolev).

• Removing the heater fan
• Removing the heater fan motor speed regulator
• Removing the air conditioning compressor
• Removing the evaporator, heater radiator and heater housing
• Removing the air recirculation mode flap drive
• Removing the capacitor

The Ford Focus 2 can be equipped with either a heating and ventilation system or a heating, ventilation and air conditioning system, which serve to create the most comfortable conditions for the driver and passengers, regardless of weather conditions.
The heating and ventilation system includes an outside air filter, a heater, a heater fan, air ducts and deflectors. Through the air ducts, the air from the heater is supplied to the windshield and side windows blowing grilles, to the central and side vents on the instrument panel, to the vents in the instrument panel frame for supplying air to the feet of the driver and passengers, and is also supplied to the feet of the rear seat passengers.

The system is controlled by turning the knobs located on the heating, ventilation and air conditioning control unit. The control unit is installed on the center console of the instrument panel.

The heater housing is installed behind the center console and is attached to the dashboard and dashboard frame.
The following are installed in the heater body: outside air purification filter (cabin filter); heater fan; fan motor rotation speed regulator; distribution dampers that direct air flows to specific zones; a heater radiator, connected by hoses to the engine cooling system, through which coolant is constantly circulating.
The air is heated by the heat of the engine coolant circulating through the pipes of the heater radiator.

Air conditioning system Ford Focus 2:
1 - capacitor;
2 - compressor;
3 - receiver;
4 - pressure sensor of the refrigerant in the high pressure pipeline;
5 - refrigerant pressure sensor in the low pressure pipeline;
6 - evaporator;
7 - low pressure pipeline;
8 - high pressure pipeline;
9 - valves for charging and discharging refrigerant

Some cars are equipped with an air conditioning system. The system is designed to reduce the temperature and humidity in the cabin. The air conditioning system is turned on by pressing the air conditioning switch button located on the heating, ventilation and air conditioning control unit, while the heater fan must be turned on.

Air conditioner evaporator Ford Focus 2

Most of the components of the air conditioning system are located in the engine compartment. Inside the car there is only an evaporator located under the dashboard in the heater housing.

Removing the cooling radiator Ford 2

The evaporator is used for heat exchange between the air entering the vehicle interior and the refrigerant circulating in the air conditioning system.

As it moves through the evaporator tubes, the refrigerant turns into gas.

The process takes place with the absorption of heat, the evaporator fins are cooled, the cold is “removed” from the fins and, with the help of the heater fan, is directed into the passenger compartment, helping to lower the interior temperature in the passenger compartment.
The refrigerant in the gaseous state flows under low pressure from the evaporator to the receiver.

Air conditioning compressor Ford Focus 2 with electromagnetic clutch

The air conditioning compressor is installed on the right side of the engine block under the power steering pump.

The compressor is driven by a poly V-belt from the accessory drive pulley. An electromagnetic clutch is built into the compressor pulley, which switches the compressor shaft on and off from the pulley according to signals from the electronic engine control unit (ECU).

compressor for ford focus 2

The receiver simultaneously performs several functions: as a filter, it cleans the refrigerant from impurities that have got into it; as a dehumidifier, it absorbs moisture condensing inside the air conditioning system and also serves as a reservoir for the refrigerant. From the receiver, the refrigerant enters the compressor, which increases the refrigerant pressure.

High pressure refrigerant vapor from the compressor enters a condenser located upstream of the radiator of the engine cooling system. Passing through the honeycomb of the condenser, the refrigerant is cooled by the counterflow of air and by the fan of the cooling system. In this case, the refrigerant passes from a gaseous state to a liquid.

The high pressure liquid refrigerant then flows directly into the evaporator, where the refrigerant changes from a liquid to a gaseous state. From the evaporator, the refrigerant is again sucked in by the compressor, and the operating cycle is repeated. Valves for charging and discharging refrigerant from the air conditioning system are installed on the high and low pressure pipelines.

Refrigerant pressure sensors are installed on the high and low pressure pipelines. The pressure sensors provide signals to the ECU, which controls the electric fan of the engine cooling system, depending on the magnitude of the coolant pressure and the vehicle speed.
In addition, according to the signals from the pressure sensors, the ECU turns off the air conditioning compressor if the refrigerant pressure in the system is too low or too high. Most of the refrigerant in the air conditioning system is under high pressure.

When working with the depressurization of the air conditioning system, avoid contact with eyes, skin and respiratory tract.

Any work with the refrigerant must be carried out only in a ventilated area. When refueling the air conditioning system, use only materials recommended by the manufacturer.

It is forbidden to carry out welding or soldering work on the units of the air conditioning system. Repair and maintenance of the air conditioning system should be carried out at specialized services.

The location of the air ducts on the dashboard frame

Arrangement and order according to the scheme

5 - air duct to the feet of the front passenger

In general, the principle of operation of a car air conditioner is similar to that of a conventional refrigerator. Freon mixed with oil circulates through the system nodes. Oil is used to lubricate moving parts, freon is a refrigerant. First, the high pressure compressor compresses the gas to a liquid state. It is then distilled into a condenser where it is cooled to zero temperature. The next item is a receiver-dryer. This reservoir contains a special moisture-retaining substance that cleans freon from excess moisture. After that, the refrigerant is in the expansion tube, where the pressure drops sharply and the freon returns to a gaseous state. The cooled gas moves to the evaporator, behind which is a fan. The air is cooled by passing through the freon. Finally, the refrigerant returns to the compressor where it becomes liquid again and the cycle repeats.

How to understand that auto compressor repair is needed?

The air conditioner does not work in the car if:

• the cooling system supplies not only cold air, but also such signs of life as noise and knocking in the area of ​​the compressor;
• the smell in the cabin leaves much to be desired;
• the supply of cold air treacherously stopped;
• the machine is still cooled, but not constantly.

All this means that the car compressor is not pumping or there is some other problem in the system.

As a rule, depressurization leads to troubles with the operation of an air conditioner. This can happen if the refrigerant was not charged in a vacuum. Because of this, water or air gets inside, which equally badly affects the operation of the device.

An unpleasant smell is created by colonies of microorganisms and molds, which multiply with pleasure in the evaporator. This dark and humid place provides them with ideal conditions. Such an undesirable neighborhood, in addition to simple discomfort, leads to a variety of diseases.

The design feature of a car air conditioner is that it receives energy for operation not from a dedicated motor, but from the engine. In order for the mechanism to be turned on and off independently, there is a magnetic coupling. It is not a direct part of the cooling system, but plays an important role in it. Often the problems of insufficient air cooling or compressor failure are associated with it. The condition of this part must be carefully monitored, since the price of the Ford Focus 2 clutch, for example, starts at 19,000 rubles. In general, this applies to any part of the cooling system. So, a professional flushing of a car air conditioner radiator will cost less than the subsequent repair of other parts, if this has not been done.

Initial diagnostics of the condition of the vehicle cooling system can be performed without using the inspection pit and lift. For this you need:

• visually assess the level of freon in the system through the receiver window;
• make sure that the radiator pipes are cold;
• try to start the compressor by connecting it to the engine directly (if it starts, there is a problem on the clutch side);
• check for oil stains on parts of the mechanism.

Auto repair shops have several standard procedures for repairing an A / C compressor and other parts.

1. Full disassembly of the air conditioner and flushing of all parts. This is especially important if a part has been replaced. If this procedure has not been performed, debris from the old ones will get into the new part, and it will have to be repaired again.
2. Diagnostics and elimination of freon leakage using special devices.
3. Refrigerant charge with pre-evacuation of the system.

Also, a guarantee is given for the work performed.

In order to face the lack of cold air in the cabin as rarely as possible, try to follow a few simple rules:

• do not turn on the air conditioner as soon as the car is started;
• do not trust unskilled craftsmen to refuel freon;
• do not forget about disinfecting the system with special means.

And the situation when the air conditioner does not turn on on a Ford Focus 2 car will happen quite rarely.
