No. Related introduction: 1. Reason: When turning on the cold air in a car, the AC switch must be activated. This starts the compressor, which is necessary to deliver cold air. 2. Brief introduction: The AC button in a car's air conditioning system represents the compressor switch, which controls the output of cold air. The car's air conditioning system includes components such as the compressor, evaporator, condenser, and expansion valve. The compressor is a crucial part of the refrigeration system, responsible for compressing and circulating the refrigerant vapor. Therefore, to activate the cold air, the AC switch must be turned on. Otherwise, only the blower will be working, delivering air at normal temperature. Both manual and automatic air conditioning systems have an AC switch. For automatic air conditioning, you first need to set the desired temperature. In hot weather, turning on the AC switch and pressing the AUTO button will allow the system to automatically adjust the interior temperature. For manual air conditioning, after turning on the AC switch, adjust the temperature to the blue position to activate the cold air.
