What are the reasons for the parking air conditioner not cooling?

The reason for the parking air conditioner not cooling is that the air conditioner radiator is too dirty. The following is the relevant introduction about car air conditioner maintenance: 1. Turn off the air conditioner when the engine is under high load: When the engine is under high load, the air conditioner should be temporarily turned off. Otherwise, if the engine overheats, it will not only affect the driving of the car but also the use of the air conditioner. 2. Keep the air conditioner clean: As time goes by, the owner should regularly replace the air filter element to maintain the normal operation of the internal parts of the air conditioner. At the same time, do not stack items near the air intake to avoid blocking the air intake, which will hinder the air circulation of the air conditioning system.
As someone who frequently deals with car air conditioning, I find that a parking air conditioner not cooling is often due to insufficient refrigerant or leaks—it's like a fridge without Freon that can't cool down. The compressor is the core component; if it's broken, there will be noise but no cold air output. If the condenser is clogged or dirty, poor heat dissipation will also affect cooling. On the electrical side, blown fuses or relay failures may cause the system to lose power. If the fan motor isn't running, the air won't circulate, and the temperature won't drop. Sometimes, the expansion valve gets stuck and can't control the coolant flow, or external dust buildup and internal filter blockages need timely cleaning. When you notice no cooling, prioritize checking the refrigerant level and electrical connections. Use soapy water to test for leaks, then decide which part to repair based on the symptoms. Don't delay, as it could lead to bigger, costlier repairs later.
