What's the reason for the Wuling Rongguang air conditioning compressor not working?

[KadenDella]

The compressor may not be working due to insufficient refrigerant. Below are the functions of a car air conditioning system: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system generates cold air to lower the temperature inside the cabin; in winter, except for large commercial vehicles that use independent combustion heaters for heating, other vehicles generally utilize the car's waste heat for heating. 2. Humidity regulation: Humidity significantly affects the thermal comfort of passengers inside the vehicle. The humidity inside the cabin should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the capability to regulate cabin humidity, which can only be adjusted by using ventilation systems or the integrated heating and cooling air conditioners found in high-end luxury vehicles.
