What problems will occur if the car air conditioning switch is broken?

Phenomenon: Poor contact of the contacts or abnormal operation of the pressure switch may cause the compressor to not work or fail to provide normal pressure protection. The following is a related introduction about car air conditioning: 1. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and serving as an important ventilation device to ensure safe driving. 2. Layout form: The layout form involves assembling the evaporator, heater radiator, centrifugal blower, control mechanism, etc., together, which is called the air conditioning unit assembly.
Last time my AC switch broke and it really gave me a hard time. The AC wouldn't turn on at all, the fan wouldn't spin, and the cooling function failed. Driving in summer felt like entering a sauna, sweating profusely was extremely uncomfortable. Sometimes I couldn't even adjust the temperature, the constant switching between hot and cold easily led to catching a cold. The switch failure might be caused by oxidized internal contacts or spring failure leading to poor contact. I suggest first checking if the AC fuse is blown, or trying to restart the vehicle, but in most cases you'll need to replace the switch. Delaying too long might affect the evaporator or compressor, making repairs more expensive. Regular cleaning of dust on the control panel can prevent similar problems, avoid using the AC for extended periods in humid environments. Be especially careful about heat risks in hot weather, don't wait until health problems emerge to regret it.
