What are the reasons for the Wuling Sunshine's air conditioning not cooling?

[Barbosa]

The reasons for the air conditioning not cooling are as follows: 1. No air or low air volume from the air conditioning: It is necessary to check whether the air filter is dirty, whether the blower can operate normally, and whether the air conditioning flap motor can switch normally; 2. Lack of Freon in the air conditioning system: It is necessary to check whether the system is leaking. After the repair is confirmed, add Freon to the standard range; 3. Dirty radiator condenser: A fault in the engine cooling system leads to excessively high water temperature, such as the cooling fan not working, resulting in poor heat dissipation of the radiator and condenser; 4. Air conditioning pressure sensor: Incorrect data from sensors such as the evaporator box sensor causes the air conditioning system to fail to adjust correctly; 5. Damage to the air conditioning compressor adjustment solenoid valve: Damage to the air conditioning compressor clutch or internal damage to the air conditioning compressor; 6. Fault in the air conditioning system wiring or control unit.
