Problem overview

Some Ford Mustang owners report experiencing issues with their AC systems blowing hot air even after replacing the control module, drier, evaporator, and condenser. Common causes of this problem include insufficient refrigerant levels, which can lead to hot air being emitted from the AC. Additionally, a stuck blend door that fails to switch between vents may also result in hot air blowing. Problems with the actuator motor controlling the blend door can further contribute to AC malfunction. Furthermore, a faulty AC compressor is another potential reason for the system not cooling properly. Owners are advised to check refrigerant levels, inspect the blend door and actuator motor, and ensure the AC compressor is functioning correctly. Consulting a professional mechanic for a thorough diagnosis is recommended to identify the exact cause and facilitate necessary repairs.
