What causes the BMW 5 Series air conditioning to stop blowing air?

[DelJuliet]

Here are the reasons why the BMW 5 Series air conditioning may not blow air: 1. Blower motor failure: The blower motor is the core component responsible for air output in the air conditioning system. If it is damaged, the car's air conditioning will inevitably stop blowing air. Blower motor failure may be caused by overheating damage to internal coils or capacitor failure. You can check for faults by turning the car's air conditioning speed and airflow to maximum and listening for the blower motor sound. If a fault is detected, it needs to be repaired at a 4S shop or repair shop. 2. Clogged air filter: A clogged air filter is one of the causes of blocked air ducts and the most common one. Outside air passes through the air filter before entering the car, which adsorbs many airborne particles and is prone to clogging. You can remove the air filter to check if it is clean and clean it if dirty.
