Why Can Cooling Still Occur Without Turning on the AC?

[Harriet]

There are several reasons why cooling can still occur without turning on the AC: Reason 1: It may be caused by a broken compressor clutch. If the compressor clutch is damaged, the clutch will remain engaged continuously, so the air will cool regardless of whether the AC button is pressed. Solution: It is necessary to visit a professional repair shop or 4S store to inspect the compressor clutch. If the clutch is broken, this component needs to be replaced, and the entire compressor may also need replacement. Reason 2: It may be due to the low temperature of the internal evaporator. Water vapor may condense into ice near the evaporator. When the external circulation is turned on, air flows through the evaporator, absorbs heat, and then blows into the cabin, resulting in cold air. Solution: As the ice on the evaporator melts and the temperature of the evaporator rises, the cold air will gradually turn into normal-temperature air. The car AC switch controls the compressor when the air conditioning is cooling. This function is divided into manual and automatic air conditioning systems. Both manual and automatic air conditioning systems have an AC button. For automatic air conditioning, simply setting the desired temperature allows the system to automatically select and open or close different air vents based on light sensors and multiple interior temperature sensors, automatically adjust airflow, and turn on as needed.
