Can the Air Conditioner Cool Without Starting the Car?
1 Answers
No, the air conditioner cannot cool without starting the car. Below is an explanation regarding the situation when the car air conditioner fails to cool: 1. Compressor operation status: Check if the drive belt is broken or loose. If the drive belt is too loose, it will slip, accelerate wear, and fail to transmit power. Also, check for noise inside the compressor and whether the compressor clutch is slipping. 2. Condenser and fan status: Check if the condenser fins are covered with dust. If the condenser fins are covered with dust, the condenser's efficiency will be greatly reduced. Also, ensure the condenser fan is operating properly. 3. Refrigerant level check: If you see a large number of bubbles through the sight glass, it indicates insufficient refrigerant. If you pour water on the condenser to cool it and still see no foam in the sight window, it indicates excessive refrigerant. 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.
