Where is the car air conditioning cooling button located?

The blue button on the left side of the car represents the air conditioning cold air. Below are detailed introductions to the components of the car air conditioning system: 1. Air conditioning pressure sensor: Usually installed after the dryer, it is used to detect the hydraulic pressure of liquid refrigerant flowing through the expansion valve. Three wires: detect high pressure and low pressure. When a car collision causes refrigerant leakage and compressor oil loss, to prevent compressor damage due to lack of oil, once low pressure is detected, the compressor power is quickly cut off. When high pressure is detected, the compressor power needs to be reduced to avoid wasted work. 2. Air conditioning temperature sensor: Usually installed inside the temperature sensing package, it is the evaporator temperature sensor. When the temperature drops to a certain level, the compressor needs to be shut down. Further cooling would cause frosting, eventually leading to ice blockage. 3. Air conditioning compressor relay: Usually installed on the compressor, it is used to control the compressor's start, stop, and power switching functions.
