Volkswagen Tiguan AC not working, warm air blowing despite fan operation on Volkswagen Tiguan

Some Volkswagen Tiguan owners report experiencing issues with their AC systems blowing warm air despite the fan operating. This problem can be attributed to several factors, including low or overcharged refrigerant, which can prevent the AC from cooling effectively. Additionally, a malfunctioning compressor is a common culprit for AC failures in the Tiguan. Owners may also find that dirty condenser or evaporator coils contribute to the warm air issue, even when the fan is working properly. Other potential causes include a faulty blend door actuator or defective evaporator temperature sensor, which may disrupt the AC's cooling function. Furthermore, a bad AC pressure sensor or issues with fuses and relays could also lead to problems with the AC system. It is advisable for owners to check these components to diagnose and resolve the warm air issue effectively.
