I have a problem with my Audi T Sport (99) that I was hoping someone could help me with?!? My car is steaming up really badly at the moment, especially after it's been raining. It has a digital climate control display and most of the time it won't let me put the air con on (the light comes on and goes out immediately). I've even found dampness in my passenger footwell, does this have anything to do with it? I had a look at my front windscreen and there doesn't appear to be any leaks or cracks. There is a small crack in plastic between the windscreen and the bonnet but nothing too major. Please, if anyone could help resolve this problem I would be incredibly thankful. Cheers.
