Why is the BMW car air conditioner not cooling?
2 Answers
The reasons why the BMW car air conditioner is not cooling are: 1. Leakage of the air conditioner refrigerant; 2. Damage to the car's compressor; 3. Problems with the air conditioner button; 4. Single cooling unit failure; 5. Fault in the internal unit or mainboard of the air conditioner. Solutions: 1. Adjust if the belt is too loose; 2. Regularly clean the surface of the condenser; 3. Add refrigerant. Taking the BMW 5 Series as an example, its body dimensions are 4998 mm in length, 1901 mm in width, and 1559 mm in height, positioned as a high-end sedan. In terms of power, the BMW 5 Series is equipped with a 2.0T high and low power engine, with maximum power outputs of 184 horsepower and 252 horsepower, matched with an 8AT transmission.
I've encountered the issue of BMW air conditioning not cooling many times. BMW owners know how unbearable the heat can be in summer, especially affecting the driving mood. The most common cause is refrigerant leakage. BMW's air conditioning pipelines are designed with precision, making them prone to leaks with slight aging or impact. The compressor is also a key component—if there's no sound after starting, it's likely broken or has an electrical issue. A non-functioning fan can also lead to poor heat dissipation and reduced cooling effect. Clogged filters are quite common too; with too much dust, airflow is blocked, and the air blown out isn't cold. I've had it repaired myself, and the technician recommended regular checks on the air conditioning system to avoid major problems. By the way, sometimes the electronic control module malfunctions—replacing it can be expensive, but it must be addressed promptly to prevent damage to other components. Overall, early detection and repair save both money and hassle.
