What is the function of the A/C button in a car?

[EvanAnn]

The A/C button in a car's air conditioning system is the switch for the vehicle's air conditioning compressor. Pressing the A/C button activates the air conditioning compressor. ON to turn on: On the car's light lever, there are ON and OFF options. ON means to turn on, and OFF means to turn off. SEL button for menu selection confirmation: Generally found on the multifunction steering wheel. The OK button and SEL button have exactly the same function, but some cars use SEL while others use OK. VOL+/- buttons for volume adjustment: VOL is the abbreviation for the word volume, which can adjust the volume of the car's audio system. MUTE button for muting: It can mute the sound with one press.
