Why is the car air conditioner not working?

[SanGenevieve]

There are several reasons why a car air conditioner may not be functioning: 1. Insufficient refrigerant: Typically, terms like refrigerant, coolant, Freon, or refrigerant gas all refer to the air conditioning refrigerant. Solution: Add air conditioning refrigerant. 2. Improper tension of the car air conditioner belt: If the belt is too tight, it can directly cause the compressor to seize and stop running; if the belt is too loose, it can lead to slipping in the power transmission of the compressor, resulting in intermittent cooling and reduced power. Solution: Adjust the belt tension. 3. Issues with the electrical system: For example, if there is a short circuit or open circuit in the wiring, the power transmission path is directly lost, and the electromagnetic clutch cannot properly control the compressor's operation. Since the actual vehicle cannot be seen, an accurate judgment cannot be made. Solution: It is recommended to promptly visit a professional auto repair shop or a 4S store for inspection by the staff, and follow their diagnosis.
