What Causes the Interior Air Circulation to Fail?

[Louis]

Most cases of interior air circulation failure are caused by damage to the flap motor. Seasonal car air conditioning maintenance methods are as follows: 1. Replace the cabin air filter: For car air conditioning, the cabin air filter—also known as the pollen filter—is the most critical component. Its primary function is to filter the air entering the cabin from the outside, removing microscopic particles, pollen, bacteria, dust, and even twigs or leaves. This purifies the cabin air, but contaminants accumulate in the filter, so it needs replacement when excessively dirty. 2. Clean the air conditioning system manually: Beyond the cabin air filter, the internal ducts also require maintenance. Especially during the rainy season, unused air conditioning systems may experience warm weather and high humidity, fostering bacterial growth. Other issues may include poor cooling performance and reduced airflow.
