What is the reason for the BMW 320 air conditioner not cooling?
2 Answers
BMW 320 air conditioner not cooling reasons are as follows: 1. The car condenser is too dirty: The condenser is part of the car air conditioning system, and its main function is heat dissipation. If the vehicle is used in a poor environment, dust and other dirt can easily adhere to it, leading to poor heat dissipation performance, which in turn reduces the cooling efficiency of the air conditioner. 2. The car air filter has not been replaced for a long time: The car air filter is a 'filter barrier' for the air entering the car from outside. If the car air filter is covered with dust, the air output of the air conditioner will decrease, and the corresponding cooling effect will be significantly reduced, affecting the car's cooling performance. Moreover, not replacing the air filter for a long time can also pollute the air inside the car and increase the noise level. 3. The car air conditioner lacks refrigerant: A lack of refrigerant is also an important reason for the car air conditioner not cooling. Once it is determined that the lack of refrigerant is causing the air conditioner not to cool, simply adding the corresponding refrigerant at a car repair shop can solve the problem.
I've been driving a BMW 320 for almost ten years and have encountered several instances where the air conditioning stopped cooling, which is actually quite common. Usually, it's due to insufficient refrigerant because the sealing rings in BMWs tend to age and leak easily; or the compressor might be broken, as it wears out significantly with prolonged use. You can first check the fuse box yourself by pulling them out to see if any are blown; then listen for any noise when the compressor starts—if there's no sound, it might indicate a fault. Sometimes, a stuck fan or a short circuit in the circuit board can also cause it to stop working. Don't force it to avoid damaging other components; instead, quickly take it to a repair shop to have a mechanic check the refrigerant pressure. This way, you won't have to endure the heat and sweat during hot weather, which is uncomfortable and affects concentration. Regularly replacing the refrigerant can prevent this issue. I service my air conditioning system every year before summer.
