Yesterday I went on a lengthy drive (first day it was about 40 degrees in Wisconsin), I came home and turned off my car and back on.

Now my drivers side window switch doesn't work. Every other window switch works on the drivers side and all other doors.

I figured it may be an issue with the window regulator but I also noticed it knocked out my window lock feature and mirror adjuster (the illumination doesn't even work)

Any ideas on what would simultaneously knock out all three switches? I would go with the wiring harness connecting to the door, but it's hard for me to believe it took out all three components within a five minute battery shut off.

Thanks for any input.

Car make and model:
2003 Audi a4 1.8t Quattro, automatic/slap stick

 

Well I guess if I can't check the boost gauge to trouble shoot it, no one wants to help.

Home for lights being on also not working.

 

If everything that requires voltage to work isnt working, start there. Fuse. Door connector. You might have to trace voltage with a meter to see where your losing it.
