Which Button Turns Off the Car Air Conditioning?

[LeLola]

The AC switch in the car's air conditioning control area is essentially the on/off button for the air conditioning system. Pressing the AC button will turn off the car's air conditioning. Methods for troubleshooting car air conditioning system issues include: 1. Check if the condenser fan is operating normally; 2. Observe the frosting condition of the low-pressure circuit—surface frosting is normal; 3. Listen for any unusual noises or knocking sounds during compressor operation—their presence indicates an issue; 4. Feel the high and low-pressure pipes of the refrigeration system—hot high-pressure pipes and cool or icy low-pressure pipes are normal. Precautions for using the air conditioning system include: 1. Avoid setting the temperature too low; 2. Adjust the direction of the air vents; 3. Avoid prolonged use; 4. Occasionally use higher fan speeds; 5. Turn off the air conditioning when driving at low speeds.
