Car air conditioner failure may be due to severe internal wear of the compressor, preventing normal operation. Alternatively, it could be caused by electrical system faults that prevent the car air conditioner compressor from functioning effectively. Below are more maintenance methods for car air conditioner compressors: 1. Timely addition of car air conditioner additives: When using the car air conditioner compressor, it is necessary to promptly add air conditioner additives. The main function of these additives is to enhance the sealing of the air conditioner compressor, reduce wear, effectively lower noise produced by the air conditioner, and improve the compressor's working efficiency. 2. Timely addition of refrigeration oil: After prolonged use, the car air conditioner compressor also requires timely addition of refrigeration oil. If the refrigeration oil fails, it can easily damage the compressor. 3. Check the tightness of the drive belt: During operation, the tightness of the air conditioner compressor's drive belt also affects the air conditioner. If the drive belt is too loose, the components of the electromagnetic clutch in the compressor will experience increased load. If the drive belt is too tight, the compressor may not operate. Therefore, it is necessary to regularly check the tightness of the drive belt.
