What Causes No Airflow from BMW Car Air Conditioner?
1 Answers
Common faults causing no airflow from BMW car air conditioner vents include the following: 1. Blower motor failure: The car blower motor is a crucial component for air conditioning airflow. If the air conditioning compressor fails during use, the car air conditioner will definitely not blow air. Overheating damage to the internal coil or capacitor failure of the blower motor are significant causes of blower motor failure. You can turn the car air conditioner to maximum and listen for the blower motor's sound. If the blower motor is confirmed faulty, it needs to be addressed at a 4S shop as it's difficult to resolve on your own. 2. Clogged air filter: The air filter is a major and relatively common reason for no airflow from the air conditioner. During operation, the car air conditioner absorbs many impurities from the air, leading to a clogged air filter. If there's no airflow, you can remove the air filter to check if it's clean. If it's too dirty, it should be replaced promptly at a 4S shop or repair shop. If you can handle it yourself, you may also replace it. 3. Control system failure: If neither the blower motor nor the air filter is the cause of no airflow, it might be due to a fault in the air door, air conditioning computer, or control switch. Control system switches generally don't fail often. It's recommended that the owner visit a 4S shop for inspection, as this will make the process simpler.
