With the onset of hot weather, many motorists are concerned about the health of the air conditioning system. If she is in in perfect order, then there are no problems with the operation of the air conditioner. But what if cool air stops blowing from the deflectors?
The car air conditioning system includes many components and parts, each of which performs its specific function. Violations in the operation of at least one element can significantly affect the performance, or even completely disable the unit. One such device is a compressor.
The compressor is perhaps the most important and expensive element climate system any car. However, its design contains another node, the purpose of which is to make the compressor do its job. This is an electromagnetic clutch for turning on the air conditioner.
Coupling provides 
mechanical connection of the compressor pulley and its drive shaft. When the system is disabled, the pulley rotates freely, and the internal mechanical part compressor remains stationary. But as soon as you press the A/C button, an electromagnet pulls the clutch plate against the pulley, and the compressor mechanisms start working.
In most cases, the couplings are disposable and are not supplied as spare parts. Therefore, repairing the air conditioning compressor clutch on a car at first glance turns out to be impossible, and auto repair shops are forced to resort to different ways recovery. However, some models of compressors still provide for its replacement.
A malfunction of the electromagnetic clutch can be identified by the following symptoms:
- the switched on air conditioner does not provide cold air supply;
- when you press the power button (A / C), the first fan speed does not turn on;
- the characteristic click of the electromagnetic clutch is not heard;
- the air conditioner suddenly stopped cooling.
If you have similar symptoms, you should immediately contact a specialist who will conduct a detailed diagnosis, determine the non-working unit, and therefore what kind of work will require repair of the air conditioning compressor clutch.
Unit check 
usually consists of the following operations:
- measuring the working pressure in the system (it must be at least 20 atm);
- checking sensors and thermostat;
- examination electrical circuits and connectors;
- checking the compressor and electromagnetic clutch.
The last procedure is performed removed belt auxiliary units. Pressing the air conditioner on button should be accompanied by a click (not always), and when the compressor pulley is turned by hand, slight resistance should be felt. In the free state, the pulley usually rotates very easily.
As mentioned above, the repair of the electrical clutch of the air conditioning compressor, as a rule, comes down to replacing it, and only in some cases only experienced craftsmen are able to repair the part.
The most frequently occurring 
clutch malfunction is a break in the thermal fuse, which is designed to protect the clutch from overheating. The nominal response temperature is 190 C °, and it only works once. The malfunction is diagnosed with a multimeter for an open circuit. The clutch is replaced with the same value. The fuse is usually filled with compound, which will need to be removed. New element soldered to the contacts with refractory tin solder and filled with a suitable epoxy composition (the composition must be designed for a temperature of at least 220 ° C). In addition to the fuse, there is also a break in the electromagnet coil. Such a malfunction is quite rare and happens if a “bug” was installed instead of a thermal fuse. In this case, the electromagnet is no longer subject to repair.
Another clutch failure is associated with bearing wear and is expressed in increased noise. This is checked by rotating the compressor pulley. The pulley should rotate easily, with no extraneous sounds, such as rumble and rattle, should not be. Worn out 
the bearing gets very hot during operation, and the speed of rotation of the compressor pulley is approximately twice the speed of rotation crankshaft. Overheating of the bearing often causes the failure of the thermal fuse.
A new bearing is selected according to the marking, and the manufacturer plays a very significant role. You should not save on this, cheap copies have a very small resource and can fail after a very short time. The replacement procedure is often fraught with certain difficulties. Firstly, the landing is made with a large interference fit (there are also stressed with preheating seat). Secondly, the bearing is additionally fixed by point-filling of the edges, which excludes its displacement when the assembly is heated during operation.
To carry out the replacement work, special equipment and extreme care, as there is a risk of deformation of the pulley and damage to the bearing seat. This, in turn, can lead to radial runout pulley, increased wear and cliff drive belt and compressor failure.
If a tight fit is used, then the pulley is first heated to a temperature of 200-250 degrees, and then pressed in new bearing. It is important to control the temperature strong heat can lead to a violation of the structure of the material and even warping of the part.

Clutch (electric clutch) connecting rear axle Hyundai, KIA
All-wheel drive scheme with electromagnetic hyundai clutch, KIA
On many cars, all-wheel drive is pluggable. All-wheel drive is also arranged on Hyundai cars, KIA, drive on rear wheels here connected automatically, through an electromagnetic clutch.
All-wheel drive electromechanical clutch
The clutch is controlled by the Hyundai, KIA all-wheel drive control unit. The principle of operation of an electromechanical clutch is almost the same as that of a clutch. When voltage is applied to the clutch, the discs inside the clutch are pressed against each other and torque is transmitted to the rear wheels through them.
Four-wheel drive is connected by Hyundai, KIA only at the moment of slipping of the front wheels, and approximately after the second rotation of the wheel. When the need for all-wheel drive disappears, it turns off. Also, the drive is switched off when a certain speed threshold is exceeded, because the clutch operation is not designed for high speeds.
There is a four-wheel drive test lamp on the instrument panel. When the ignition is turned on, the lamp lights up and the system performs a self-test. If everything is in order, the lamp goes out. In the presence of malfunctions, the lamp will continue to burn.
Unfortunately, there are no identification signs that the drive has turned on in the car. But you will easily understand this when you get stuck and start to slip. When the rear wheel drive is connected, you will feel a slight push, and the car will slowly climb out of the blockage, do not force the car to slip, because of this, the clutches in the clutch burn out.
Torque to rear wheels is transmitted through the transfer case (2), front cardan (4), electromagnetic clutch (5), rear cardan (6), rear axle gearbox (7) and rear wheel drives.
All-wheel drive transmission
Vehicle all-wheel drive transmission diagram
1 - gearbox, 2 - transfer case, 3 - front wheel drives, 4 - front cardan gear, 5 - electromagnetic clutch, 6 - rear cardan gear, 7 - rear axle gearbox, 8 - rear wheel drives.
Transfer case
The transfer case is rigidly attached to the gearbox housing. The drive for the razdatka is the differential box. The transfer box itself is two-stage. center differential there is no razdatka, and the redistribution of torque between the axles is performed by an electromagnetic clutch, depending on road conditions.
Shafts cardan gears made of thin steel. Electromagnetic clutch transmits torque to the rear wheels only when the clutch is partially or completely blocked from the signal from the four-wheel drive control unit.
The drive unit receives information from the engine control unit and, based on the data received, turns on or off the clutch, thus applying or removing torque to the rear wheels.
The block receives the following information:
- longitudinal acceleration of the car (from the acceleration sensor under the dashboard console)
- vehicle speed and wheel speed difference (from wheel sensors)
- braking mode (from the ABS unit)
The electromagnetic clutch is maintenance-free.
A new clutch costs from 45,000 rubles to 60,000 rubles, you can purchase a rebuilt clutch from us with a guarantee for 25,000 rubles. We give a 3 month warranty on our clutch.
Compressor clutch on car air conditioner- This is a fairly simple device, consisting of only three main parts:
- electromagnet coil;
- belt pulley;
- pressure plate (driven disk).
You can also add fasteners (bolts, retaining rings) and shims to this list.
Typical malfunctions and their symptoms
Most often you have to deal with two 
the main breakdowns: wear of the pulley bearing and malfunction of the electromagnet. The destruction of the bearing is indicated by a characteristic hum that is constantly heard, regardless of whether the air conditioner is turned on or not.
If the bearing is not replaced in time, play in the pulley may occur. In this case, it will touch the pressure plate, emitting an unpleasant rattle and the smell of a burnt clutch.
If the electromagnet fails, then the plate does not press against the pulley and, accordingly, the compressor shaft does not rotate. Sometimes this is accompanied by smoke and the smell of burnt insulation, and the fuse blows.
Is dismantling necessary?
As a rule, in order to repair the compressor, it has to be 
dismantle. At the same time, naturally, freon from the air conditioner merges. After the repair, the air conditioner needs to be refilled again, and this is additional money. Is it possible to remove the compressor clutch without removing the compressor itself and without violating the tightness of the system?
Repair of the air conditioning compressor clutch on a car without dismantling, but not on all car models. Some manufacturers place the compressor in such a way that removing the belt, pulley and solenoid coil is quite simple. In other cases, you will have to remove the wheels, bumper or other parts, but the compressor itself can be left in place. Well, and finally, in the third case, complete dismantling is indispensable. How is the situation on your car, you can check with a car service employee. At the same time, he will tell you how long the procedure will take and how much it will cost.
The easy way is to replace a failed node
The most obvious solution is to replace the entire clutch. True, in the official dealer center You will most likely be told that this part is not sold separately, and they will offer to change the entire compressor assembly. In fact, original couplings exist, although they are rarely found on sale. However, you can save money by using non-original spare parts.
The replacement procedure itself is simple, but without experience, and even without special tools there is a risk of damaging the compressor housing or refrigerant pipes (especially if you try to do this without removing the entire compressor). Therefore, it is better to leave it to car service specialists.
If you want to save money, then you should consider the possibility of restoring a faulty node.
Bearing replacement
When replacing the bearing, the repair of the air conditioning compressor clutch occurs in stages. To replace a worn bearing, the mechanic must remove the pulley, press out the old bearing, and install a new one. Before putting everything back together, the master evaluates the condition of the friction surfaces of the pulley and pressure disk. If they show signs of rust (and they almost always do), they are sanded down to ensure a good grip.
After that, the assembly is reassembled and the gap is adjusted with washers. The result will be noticeable immediately - an unpleasant hum will disappear, the pulley will rotate almost silently.
Electromagnet Diagnostics
Repair of the electric clutch of the air conditioner compressor 
includes such milestone as diagnostics of an electromagnet. If the electromagnet does not work, this does not mean that it has burned out. Perhaps the problem is in the power circuit and the coil simply does not receive voltage. To find out, we must connect the magnet directly to a 12V source. If the plate does not press against the pulley in this case, then the coil will have to be removed and diagnosed with an ohmmeter.
If the resistance is close to zero, then the electromagnet has really burned out. It remains only to be replaced. If the device shows infinity, then you need to check the condition of the thermistor, which is located on the coil under a layer of epoxy. Many manufacturers install this resistor as a fuse, and when overheated, it often burns out, protecting the winding from short circuit. It is enough to replace the thermistor (in extreme cases, short it with a jumper), and the magnet will work again.
Final step - clearance adjustment
After any manipulations with the clutch, it is necessary to correctly set the gap between the pulley and the pressure plate. In most compressor models, this gap should be in the range of 0.3-0.5 mm. If it is smaller, the pulley will catch the plate during rotation. If there is more, the platinum will not be pressed tightly and will begin to slip. In both cases, this will cause the plate to overheat and may even damage the compressor.
After the repair is completed, it remains only to turn on the air conditioner and enjoy the pleasant coolness in the cabin.
