What Causes a BMW's Air Conditioning to Suddenly Stop Blowing Air?
1 Answers
BMW's air conditioning suddenly stops blowing air for the following reasons: Blower motor failure: The blower motor is the core component that determines whether the car's air conditioning blows air or not. If it is damaged, the car's air conditioning will inevitably stop blowing air. Blower motor failure may be caused by internal coil overheating damage or capacitor failure. You can determine if there is a fault by turning the car's air conditioning speed and air volume to the maximum and listening to the sound of the blower motor. If there is a fault, it needs to be repaired at a 4S shop or repair shop. Clogged air filter: A clogged air filter is one of the reasons for the above-mentioned air duct blockage and is also the most common one. Outside air is filtered through the air filter before entering the car, which adsorbs many impurities from the air, making it prone to clogging. You can remove the air filter to see if it is clean. If it is too dirty, you can replace it with a new filter yourself. Control system failure: If it is not the above two reasons, then the car's air conditioning control system has a problem. The air door, control switch, or car air conditioning computer could be the cause of the fault. This is difficult to diagnose, and it is also challenging to repair on your own, requiring a visit to a 4S shop for repairs.
