How to Solve the Problem of Weak Airflow in Car Air Conditioning?

[McCatherine]

A dirty air conditioning filter with poor permeability can obstruct air circulation, resulting in weak airflow from the vents. In such cases, the filter should be replaced promptly. During operation, the evaporator may accumulate moisture on its surface, which over time can trap dust and severely block airflow. Cleaning the evaporator is relatively complex. When the internal circulation mode is activated, air circulates within the car without drawing in external heat, creating a cooler sensation. However, this mode lacks the resistance from outside air. The air conditioning ducts located under the dashboard are difficult to clean. Compressed air can be used to blow out dust or any debris, which may help increase airflow.
