Why Is There No Air Coming from the Car Air Conditioner?
2 Answers
There might be no air coming from the car air conditioner due to a blower malfunction or a clogged air filter. Specific reasons: The blower is the core component that determines whether the air conditioner blows air or not. If it is damaged, the car air conditioner will inevitably fail to produce airflow. Causes of blower malfunction may include overheating and damage to internal coils or capacitor failure. Outside air passes through the air filter before entering the car, which traps many airborne particles, making it prone to clogging. Solutions: You can check for blower malfunction by turning the car air conditioner's fan speed and airflow to maximum and listening for the blower's sound. If there is a malfunction, it is necessary to visit a 4S shop or repair shop, as it generally cannot be fixed by oneself. You can remove the air filter to check if it is clean; if it is too dirty, it is recommended to replace it with a new one.
A few days ago, the air conditioner in my car suddenly stopped blowing air, which was really frustrating. I thought about it, and there could be quite a few possible issues. The most common one is a faulty blower motor—if the motor burns out or gets stuck, no air will come out. A blown fuse can also cause no airflow; you can check the fuse box to see the status of the fuse corresponding to the blower. Another common reason is a dirty cabin air filter blocking the air intake, especially if it hasn’t been replaced for a long time. I’ve also found that in some cars, the air blend door actuator fails, causing the damper to be in the wrong position and blocking the air duct. Wiring issues shouldn’t be ignored either, such as a loose blower motor harness connector or corroded circuit boards, which can also lead to no airflow. In my opinion, start by checking the fuse and the filter—these two you can handle yourself.
