Mackin'A8

My 2000 A8 has an interesting problem, the driver's rear view mirror will only work when it rains or gets wet. After there is drying out, it fails to move when I need to adjust it. Also, there is a film beginning to accumulate on it, could it be the electrochromatic effect coming off? Any one with any ideas. I have 81 k on it and an extended warranty. Thanks

Sounds like corrosion on the terminals in the door, but who cares-- you have a warranty! Put a few more things on the repair list (come on-- its an A8-- that should not take too long!) and get them all taken care of. How's your transmission doing?
