1998 A6 Quattro Avant Electrical Problems
 

I recently purchased a '98 A6 Quattro Avant. At the time of purchase, everything ran fine. About 2 months after purchase, the windows, heated mirrors, heated seats, and sunroof stopped functioning. I took it to a shop and the guy said that the window relay looked all burned up. I got the ignition switch changed hoping this would solve the problem but it did not. Where exactly is this relay?
