The last few days I've noticed some codensation (fog) builing up on the outside of my windshield...it only seems to happen when my A/C is on. Is this a problem of some sort? I've owned several cars and this has never happen before. It has been hot and humid where I live lately. Should I get something like this checked out? 2003 A4 1.8TQ

 

When the AC cools the windshield down past the dew point, thats when condensation builds up.

 

Just go get some anti-fog rain X from walmart or somthing pluse rain X lopoks really cool when it rains! you like dont even have to use your wippers! well ya youdo ok i am freak.
