The reasons for the failure of car air conditioning not cooling are: 1. Lack of refrigerant, insufficient refrigerant in the air conditioning system pipelines, resulting in reduced pressure; 2. Long-term lack of maintenance, clogged air filter and condenser; 3. Malfunction of the air conditioning compressor; 4. Loose drive belt of the air conditioning compressor, causing a decrease in compressor speed; 5. Faulty remote control or air conditioning receiver; 6. Four-way valve or high-low pressure gas leakage in the compressor, rendering the air conditioning ineffective. The solutions for car air conditioning not cooling are: 1. Add air conditioning refrigerant; 2. Check the pipelines in the car air conditioning system and whether the air conditioning pump components are damaged; 3. Use a high-pressure water gun to clean the condenser's heat sink, then dry it with a high-pressure air gun.
