Is the car AC light on or off?

AC light on means it's on. Here's an introduction to the use of the car air conditioning AC button: How to use the AC button: The car AC switch controls the compressor when the air conditioning is cooling. This function is divided into manual air conditioning and automatic air conditioning. Both manual and automatic air conditioning have an AC button. For automatic air conditioning, you only need to set the desired temperature, and it will automatically select and open or close different air vents, adjust the air volume, and turn on based on light sensors and multiple interior temperature sensors. The role of AC: AC is the control button for the air conditioning compressor. Many car models automatically turn on the AC when the windshield defogging function is activated because AC has a dehumidifying function, which can speed up the defogging efficiency.
The AC light indicates that the air conditioning compressor is working, which means it's turned on. I've been driving for over ten years, and the first thing I do every summer when I get in the car is press the AC button to make the light come on. This indicator is quite intuitive—when it's lit, it means the cooling system is operating. Be aware that if hot air is coming out of the vents, it could be due to refrigerant leakage or compressor failure. Automatic air conditioning systems decide when to start and stop the compressor on their own, so don't assume it's broken if you see the light turning on and off occasionally. Just set the desired temperature and let the system handle it for a worry-free experience.
