I have had a problem with my air con on my CLC200 CDI and when checked they said the condenser was faulty. However last night I was driving obviously without air con on as it wasnt working but the air was burning hot coming out almost to an extent that the vents were too hot to touch! The temperature dial was on minimum and the fans were off. Would this still be down to the faulty condenser or something else like thermostat or heater matrix etc.? Thanks.
