Why is my 2015 TDI passat blowing hot air when airconditioner is on?
After all winter, I try to air condition my car...it blows hot air.
1. the AC system might be low on refrigerant, or there might be a defect in the system. Have an AC pro look at it. 2. If the AC is OK, you probably have a defective blend/mode actuator and the door is stuck on the hot side.
