This is a problem that I have had since I bought my 1998 A6 quatro.

1: You can roll the back windows up and down from the drivers switch but not from the switches in the back. The window lock is light up on the drivers switch but you cant turn it off.
2: The brights work when you pull the turn signal towards the driver but not when you push it away from the driver. Which means that in order for you to have the brights on you have to hold the turn signal towards the driver.
3: Cruise control dont work at all.

This all sounds like it may be just one relay but after looking through the book there dont look like a relay that would control all of these items. Please let me know if you have any suggestions.
