2015 volkswagen passata ac blowing warm air
took the car to mechanic ,couldn't find a solution.
Compresser was good, freon everything they couldn't find
out why its blowing warm air. Any suggestions
If thee AC is working properly, it might not be the AC. It could be the blend/mode door in the HVAC system. It's stuck on the warm/ambient side due to a defective actuator. It's under the dashboard and isn't easy to replace due to access.
