Some background: I have a 1991 300E with premium sound package. I've been installing a pioneer deck and some components in my car, but one day while I was working on it I shorted out a wire and the #1 and 9 fuses blew.

The Problem: I got a pack of new fuses of ebay to replace the broken ones. I replaced fuse #1 and #9 and turned the car to accessory. Everything checks out fine until I start the car, the first fuse lasted a little time and the deck actually worked again and the rear headrest dropped when I hit the button. I turned it off to get a cd and put the key back in to start it and the fuse blew. Three fuses went by, everytime I would start it up it would blow.

Heres what fuse #1 does according to my fuse box: cigar lighter, switch heatable rear window, glove compartment light, rear wipe/wash system, folding head restraints/ rear compartment, radio (ortho, back rest)

I'm seriously confused, I have no clue what keeps blowing this fuse. If anybody could give me any direction so I can fix this ASAP I would appreciate it. Thanks.
