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.
Last time when I was driving, the parking air conditioner suddenly stopped working. I thought it was due to a lack of refrigerant, but after troubleshooting, I found that the fan motor was stuck. Air conditioning not cooling could be caused by a blown fuse, a dirty condenser, insufficient refrigerant, or air intrusion into the system blocking circulation. This situation worsens when temperatures are high, as insufficient heat dissipation overloads the compressor. Remember to check the battery status; prolonged parking might lead to insufficient power. Also, if the expansion valve malfunctions, the coolant flow is obstructed, naturally causing the temperature to rise. I make it a habit to regularly perform simple tests on the airflow and measure the outlet temperature with a thermometer to diagnose minor issues, saving the hassle of queuing at the repair shop. If you encounter such a situation, don't panic; first, perform basic self-checks to ensure safe driving.
I understand that lack of cooling is often due to inadequate maintenance, such as dust accumulation in filters obstructing airflow and reducing cooling efficiency, compressor wear causing it to stop running, or insufficient refrigerant leading to a broken cycle. Faulty electronic components like blown fuses or failed relays can also cause the system to shut down. Clogged condenser fins need to be cleaned thoroughly for effective heat dissipation. Developing a habit of regular inspections is crucial, with refrigerant top-ups and leak checks every quarter to prevent long-term leakage damage. Simple maintenance like this can extend the air conditioning's lifespan and save money on repairs.
