Why does the car air conditioning not cool when the vehicle is not moving?
1 Answers
Here are the main reasons why the car air conditioning does not cool when the vehicle is not moving: 1. Whether the drive belt is broken or loose: If the drive belt is too loose, it will slip, accelerate wear, and fail to transmit power. 2. Internal component damage: Noise inside the compressor may be caused by damaged internal parts, and internal wear can prevent effective compression. 3. Whether the compressor clutch is slipping: A slipping compressor clutch can also cause issues. 4. Insufficient or excessive refrigerant: If a large number of bubbles are seen through the sight glass, it indicates insufficient refrigerant. If water is poured on the condenser to cool it and no bubbles are seen in the sight window, it indicates excessive refrigerant. 5. Refrigerant leakage: Check for oil stains at the connections and seams of each device. Oil stains at the connections or seams indicate refrigerant leakage, and the relevant parts should be tightened or replaced.
