My 2001 S3's rear mirror hasnt been working correctly for a while. This didnt bother me to much at first but now its gone all wierd, There are random light patchs (un tinted) and the rest is dimmed, Its getting worse and in my opinion is dangerous, Has anybody had this happen? Any tips on how best to fix it? Whats involved in removing the mirror? Can i just fit the glass from a non auto dimmer car? Any help would be great, P.S i did try to search but i didnt turn much up on the 8L cars.
