What is the reason for the AC light not turning on?
2 Answers
The reasons for the AC light not turning on are: 1. The AC switch is burnt out; 2. The fuse is blown. The AC in a car's air conditioning system refers to the air conditioning compressor switch. When the AC button is pressed, the cooling system of the air conditioning compressor will operate. The car's AC button is located below the display screen, and its functions include: adjusting and controlling the temperature, humidity, air cleanliness, and airflow state inside the car cabin. How to use the car air conditioning AC: 1. Start the car engine after getting in; 2. Turn on the car's AC button; 3. Rotate the fan button to adjust the air volume and select the cooling or heating intensity. Precautions for using the air conditioning include: 1. Do not set the temperature too low; 2. Control the direction of the air outlet; 3. Avoid prolonged use; 4. Appropriately turn on high air volume; 5. Turn off the air conditioning when driving at low speeds.
My old car also had the AC light not working issue, and after struggling for a while, I found out it was a blown fuse. Open that small box on the left side of the driver's seat, find the fuse labeled for the AC, pull it out and check if the metal wire is broken. If it's not broken, the bulb inside the switch panel might be burnt out—these LED bulbs are particularly prone to burning out. If none of these are the issue, then you’ll need to check the compressor pressure switch or sensor. Last time, my friend’s car had the light not working because the refrigerant had completely leaked, and the system automatically cut power for protection. I suggest you first check the fuse and the AC cooling effect yourself. If the compressor shows no response at all, it’s best to have a professional mechanic check the fault codes with a diagnostic scanner.
