Press the air conditioner and check how the compressor clutch. If the clutch does not work, remove the pressure switch air conditioning system and close contacts of his jumper. Now, if the clutch is activated, it means that the system pressure is too low or too high, and the system must be inspected by a specialist workshop. If the clutch is still not working, check whether the voltage is applied to the contacts of coupling. When voltage is applied, connect the contact coupling of the compressor directly to the positive terminal of the battery. If the clutch does not work, then it is defective and should be replaced. If no voltage is applied to the contacts of the compressor, check fuse. If fuses in the order, remove and check the compressor relay (see. Fig. Relay compressor of the air conditioner). When the relay is removed and the ignition is turned on, the contacts 3 and 5 relay socket should be battery voltage. Connect pins 2 and 3 of jumper, and check if the grip. If it still does not work, then broken wiring in the circuit of the compressor.
