There are several possible reasons why a car's air conditioner may not blow air, including a faulty blower motor, which requires a visit to a 4S shop for repair. If it's caused by a clogged air filter, it is recommended to clean it promptly. For control system malfunctions, it is advisable for the owner to have it checked at a 4S shop. Below are the common reasons for air conditioner failure to blow air: 1. Blower motor failure: The car's blower motor is a crucial component for air conditioner airflow. If the air conditioner compressor fails during use, the car's air conditioner will definitely not blow air. Overheating damage to the blower motor's internal coils or capacitor failure are significant causes of blower motor issues. You can turn the car's air conditioner to its maximum setting and listen for the blower motor's sound. If the blower motor is confirmed to be faulty, a visit to a 4S shop is necessary, as it is difficult to resolve on your own. 2. Clogged air filter: A clogged air filter is a common and significant reason for the air conditioner not blowing air. During operation, the car's air conditioner absorbs many impurities from the air, leading to a clogged filter. If the air conditioner stops blowing air, you can remove the air filter and check its cleanliness. If the filter is too dirty, it should be replaced promptly. You can go to a 4S shop or a repair shop, or if you are capable, you can replace it yourself.
