What are the reasons for the BMW GT air conditioner not cooling?
2 Answers
There are many reasons why the BMW GT does not cool, mainly the following three. Refrigerant leakage or poor refrigerant quality: There are some poor-quality refrigerants on the market. If you happen to buy this type of refrigerant, it is very normal for the car air conditioner not to cool. In this case, you just need to replace the car air conditioner refrigerant. If the car air conditioner refrigerant is confirmed to be fine, then check whether it is due to refrigerant leakage. The main symptom of refrigerant leakage is that both the indoor and outdoor units of the car work, the compressor also works, but the car air conditioner simply does not have a cooling effect. Compressor capacitor damage or malfunction: If the car compressor capacitor is damaged or malfunctioning, it will cause the compressor not to work. The main symptom is that both the indoor and outdoor units of the car work, but the compressor does not rotate and may cause overheating. Car air conditioner room temperature sensor reaches the set temperature: In fact, the car air conditioner is the same as the home indoor air conditioner. If the car air conditioner room temperature sensor reaches the set temperature, the outdoor unit of the air conditioner will no longer work. The main symptom is that the air conditioner enters a shutdown state after reaching a certain temperature.
I see you're asking about the reasons why the BMW GT's air conditioning isn't cooling, which is quite common in my experience. GT owners like me, who've used the car for several years, have encountered this issue a few times. It could be due to refrigerant leakage, meaning insufficient Freon or tiny cracks in the pipes; a faulty compressor, which is located in the engine compartment and responsible for pressurizing the refrigerant—if it's not running smoothly, the cooling effect disappears; or clogged condenser or evaporator, where too much dust buildup affects heat dissipation. I've also faced issues with the fan not spinning—if the fan is stuck, it can't blow out cold air. On the electrical side, blown fuses or sensor failures can cause the AC to malfunction. A reminder to everyone: frequent use in summer makes breakdowns more likely, so regular AC maintenance is crucial, like cleaning the filter and checking refrigerant levels annually. If you notice the AC isn't cooling, don't delay—head to an authorized service center right away to avoid sweltering summer drives.
