Reasons Why the Car's Air Conditioning Doesn't Cool When the Vehicle Is Not Moving

[SanCarmen]

Here are the specific reasons why the car's air conditioning doesn't cool when the vehicle is not moving: 1. Reason one: There is an issue with the refrigerant in the car's air conditioning system. The car's air conditioning system consists of multiple metal pipes with small gaps between them. 2. Reason two: The filter screen of the filter is clogged. Excessive dirt in the car's air conditioning refrigerant and compressor oil can also clog the filter screen, reducing cooling efficiency, increasing resistance, and decreasing the flow of refrigerant to the expansion valve, leading to the car's air conditioning not cooling. 3. Reason three: The engine drive belt of the compressor is too loose, which can cause the car's air conditioning not to cool. It could also be due to reduced heat dissipation capacity of the condenser, leading to a decline in the air conditioning's cooling performance.
