What Are the Reasons and Solutions for Car Air Conditioning Not Cooling?
2 Answers
Reasons for car air conditioning not cooling: 1. Refrigerant leakage: Once the refrigerant leaks, both the internal and external units of the car's air conditioning system will operate normally, but there will be no cooling effect; 2. Compressor failure: Damage or poor performance of the compressor capacitor can cause the compressor to stop working; 3. Issues with the car air conditioning remote control device receiver; 4. Damage to the internal fan of the car air conditioning system. Solutions for car air conditioning not cooling: Since a car is a complex machine composed of many large components, car owners generally lack the expertise compared to professional repair technicians. Therefore, it is recommended to seek professional automotive technicians to conduct comprehensive inspections on the vehicle. If the issue is refrigerant leakage, professional technicians can simply recharge the refrigerant. For compressor failures or damage to the internal fan, skilled technicians can perform repairs using their expert knowledge.
I've encountered the issue of car air conditioning not cooling several times. The most common cause is refrigerant leakage, which often happens due to aging pipes or loose connections, resulting in hot air blowing when you turn on the AC. Compressor failure is another major culprit, such as belt breakage or electromagnetic clutch jamming, and a non-rotating fan can also cause the condenser to overheat. Additionally, a clogged air filter with accumulated dust can obstruct airflow. The solution requires a step-by-step approach: first, check the refrigerant pressure yourself. If it's low, head to a repair shop immediately for a refill—never attempt to add it yourself, as using the wrong type of refrigerant can damage the system. For compressor issues, consult a professional technician for part replacements, and don't delay to avoid further damage to the car. Regularly cleaning the filter and condenser is also crucial. I usually clean them every six months and inspect before long summer drives, which saves a lot on repair costs and ensures a comfortable ride.
