    Hey all

    I have a strange issue that has reared its ugly head again. I get warm and cold air through the vents even if the heater is off.

    This happened about 2-3 years ago i initally suspected it was the heater flap positioning motor (red) so i took out the whole centre console to get to it couldnt find nothing wrong and put it all back, the fault dissapeared now its back.

    When the car is on ignition (i think) and/or car is running i can hear the heater flap positioning motor (red) moving up and down.

    I think its a sensor that is telling the flap to open and close.

    any ideas where or what the sensor is?
