You don't need to turn on AC when using heater in winter. Definition of AC switch: Simply put, the car AC switch is the cooling switch of the air conditioner. AC stands for "Air-conditioning", which means air conditioning device. This button controls the activation and deactivation of the compressor, and the car air conditioner's cooling function relies on the operation of the compressor. How AC works: After turning on the air vent in a car, the air conditioner will blow air because the blower in the air conditioning system starts working at this time, so there is air flow. However, the cooling system of the air conditioner has not yet activated because the air conditioning compressor hasn't started working. After turning on the AC switch, the onboard computer receives the signal from the AC switch, then the onboard computer sends a signal to the air conditioning compressor. Upon receiving the instruction, the air conditioning compressor begins to operate, and only then does the cooling function of the car air conditioner start working.
