What are the reasons for the parking air conditioner not cooling?
3 Answers
The reasons why the vehicle air conditioner is not cooling are: 1. Insufficient or too little refrigerant, slight leakage of refrigerant. 2. Excessive refrigerant. 3. The drive belt of the car air conditioner compressor is loose. 4. Excessive impurities in the refrigerant and freezer. 5. Use of unqualified refrigerant and freezer oil. 6. Moisture has entered the refrigeration system. The solutions for the vehicle air conditioner not cooling are: 1. Check if the compressor is faulty. 2. Detect whether the refrigeration pipeline has leaked or been damaged. 3. Check if there is refrigerant. 4. Clean and replace the air filter. The function of the vehicle air conditioner is: to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue.
As someone who frequently repairs cars, I have to say that if the parking air conditioning isn't cooling, it's mostly a hardware issue. The compressor might be broken; if it's not running, cold air won't come out. Or the refrigerant might be leaking, which is common due to aging or corroded pipelines. If the fan is stuck or the motor is faulty, the heat can't dissipate, greatly reducing the air conditioning's effectiveness. Another issue could be a dirty condenser—dust buildup blocks heat exchange, leading to insufficient cooling. When I check it myself, I first listen for any unusual noises from the compressor, then use a pressure gauge to test the refrigerant pressure. If you find these faults, don't push through using it, or the temperature inside the car could spike, affecting health. It's best to get it checked by a professional shop in time. Replacing parts might cost money, but safety comes first. Also, avoid running the air conditioning for too long while parked to reduce system load.
I just encountered this issue once during a road trip when the AC stopped cooling after parking. Turned out to be an electrical problem. For instance, a blown fuse could cut off the current, or a stuck relay might cause switching failures. Loose plugs causing poor contact are also common, especially after bumpy rides that jostle connections loose. My troubleshooting was straightforward: first check the fuse box, locate the AC section, and try replacing the fuse; or gently wiggle wire connectors to check for looseness. If that doesn’t help, it might be a control module failure—modern cars rely heavily on computer controls, so it’s best not to tinker blindly. That time, I got delayed and suffered in the sweltering heat, nearly getting heatstroke. So, a reminder: always try to park in the shade and regularly inspect your electrical system to avoid such hassles.
