Why is there no air coming out of the rear vents of the Passat?
1 Answers
The reasons why there is no air coming out of the rear vents of the Passat are as follows: 1. Blower motor failure: The car's blower motor is a crucial component for the air conditioning system to blow air. If the air conditioning compressor fails during use, the car's air conditioning will definitely not blow air. Overheating damage to the internal coil or capacitor failure of the blower motor are significant causes of blower motor failure. You can turn the car's air conditioning to the maximum and listen for the sound of the blower motor. 2. Clogged air filter: The air filter is a common and important factor that can cause the air conditioning to stop blowing air. During operation, the car's air conditioning system absorbs many impurities from the air, leading to a clogged air filter. 3. Control system failure: If neither the blower motor nor the air filter is the cause of the air conditioning not blowing air, it might be due to a malfunction in the air vent, air conditioning computer, or control switch. Control system switches generally do not fail, so it is recommended that the owner visit a 4S shop for inspection, as this will make the troubleshooting process simpler.
