Misted windows
14. Feb 2011 at 21:13

Hi Guys

Need your expert help again. Last month in the cold icy weather my screen and windows misted up badly, they just would not clear. Next day realised the recirculation flap had closed over the fan not allowing outside air in to the car. Lifted up the scuttle to view it and operated the switch and nothing happened.Then it worked intermittently. Connected laptop to car and it told me that "AIR QUALITY SENSOR" had an open circuit. Where is the air quality sensor situated - can I just disconnect or can I just gaffer tape the flap open at fan. Any help gratefully recieved

Many Thanks

Steve Douglas

Just read about similiar prob someone had. When engine is cranking on starter, if voltage on battery drops below 9v it upsets the settings on recirculation switch and it closes flap. You need to press it on and then off again to reset it - very interesting - will give it a try.
