    Have the HVAC system scanned for faults. You could have a stuck flap motor.

    You may also have a very dirty or damp pollen filter because it is in the plenum chamber. If the drains are blocked, it can give these symptoms

    I've changed the pollen filter, and let off a gas to clear the smell from air con, when I turn the air con on the windows steam up but then clear, the windows will steam up again when the engine is turned off.
