Hello Peeps, brand new member..... H E L P......!!! I've had my A4 Avant 1.9 TDi '54 for a few years now, brilliant car great workhorse. BUT lately I've been having a problem with the De mist of the windscreen, nothing coming out...?? plenty of heat, plenty of blast everywhere else but not thru the de mist... ?? It was a periodical fault, annoying but it seemed to right itself.. currently its not working. I'm wondering whether its got anything to do with the thing that re directs the airflow when de mist is selected...?? The other options all work fine. Any help or advise would be gratefully received.
