Why is there no air coming out of the car's air vents?

Here are the reasons why there is no air coming out of the car's air vents: 1. Check if the air vent is open. Inspect whether the air vent switch is properly connected and if there is any short circuit. 2. The cabin air filter is too dirty. Outside air passes through the cabin air filter before entering the car's interior, which can easily cause the filter to become excessively dirty. 3. Air duct leakage. Check if the air conditioning blower motor is functioning properly, inspect the vehicle's entire electrical distribution system, and examine the battery. 4. Abnormal blower wheel. Check the air conditioning fuse to see if it has blown. Here is additional information about the cabin air filter: 1. The main function of the cabin air filter is to isolate dust, particles, moisture, and other contaminants from the air, while also providing strong sterilization and deodorization effects. This ensures that passengers do not inhale harmful gases, which could threaten their health and driving safety. 2. The cabin air filter is installed above or below the blower. Essentially, all air entering the car must pass through it. If the cabin air filter is clogged, air circulation will be poor, and the air conditioning system will naturally not blow air.
