1. The air conditioner is not cooling. When the air conditioning switch of the air conditioner is turned on, the engine speed does not increase. If you don't need air conditioning, remove the belt of the compressor, the power can be increased by more than half gear, and it has nothing to do with the car. The air conditioning compressor is scrapped when it locks up. If rupture is required, it may be the refrigerant water ingress or the oil seal rupture, which affects the incompressible liquid into the compressor, causing damage to the piston. However, it is not often encountered. The key reason why most compressors are not working is the electromagnetic clutch.
2. The exhaust valve is damaged, and the compressor electromagnetic clutch coil is burned. In general, the compressor can only be replaced if the intake and exhaust valves are broken, and the electromagnetic clutch coil of the compressor can also be replaced if it burns out. However, some unscrupulous manufacturers do not care about 3721 to treat the good as bad, so the replacement compressor should be checked by another maintenance manufacturer.
3. If the air conditioner compressor is broken, it will affect the air conditioner not working or the refrigeration is not good. Most of the fairly clear symptoms are that the compressor does not rotate, runs noisily, the pressure is abnormal, the high pressure is low, and the low pressure is high.
