I had some minor body work done on my 2001 C240 at a friend's shop. When I picked it up, almost none of the electrical components were working - turning signals, seat adjusters, side mirror adjuster, keyless entry, and fuel gauge were all not functioning!!! Oddly enough, my windows work.

Now when I dropped the car off, I was experiencing none of this issues. However I truly do believe my friend (who is baffled) when he says that he can't think of any way that they might be responsible - they took off the back right door and repainted a couple of the panels.

PLEASE HELP!!!! We've checked the fuses and those look fine. I am past my scheduled maintenance "A", since I was waiting to get it done after I got my car back from the shop. Could this have something to do with it???
