Why did the BMW 3 Series air conditioning suddenly have weaker airflow?
1 Answers
If the airflow from the car's vents is uneven, you can check whether there is an issue with the air conditioning filter, if the air ducts are blocked, or if the condenser is clogged. The specific details are as follows: Blower malfunction: The blower is the core component that determines whether the car's air conditioning can produce airflow. If it is damaged, the car's air conditioning will inevitably fail to blow air. The causes of blower failure include overheating damage to the internal coils or capacitor failure. You can listen to the sound of the blower by setting the car's air conditioning speed and airflow to the maximum to determine if there is a malfunction. In this case, it is necessary to go to a 4S shop or repair shop for servicing. Air conditioning filter blockage: A clogged air conditioning filter is one of the reasons for the aforementioned air duct blockage and is also the most common cause. Air from outside the car passes through the air conditioning filter before entering the car, which can trap many airborne particles, making it prone to clogging. In this case, you can remove the air conditioning filter to check if it is clean. If it is very dirty, you can replace it yourself. Control system failure: If the issue is not due to the above two reasons, then the problem lies with the car's air conditioning control system. Faults in the air vents, control switches, or the car's air conditioning computer could be the cause. In this case, it is recommended to go to a 4S shop for repairs.
