Hello I'm having the same exact problem the other guy is having with his BMW. I have a 1997 Toyota Camry, I recently had a new engine installed because the old one threw a rod.
I go get my car from the mechanic and I'd say two hours later all my dashboard lights go out. Can't roll my windows up, odometer & speedometer gone out. Every time I put a fuse in there it blows right away. I took it right back to the mechanic that put my engine in he's just as confused he claims "He didn't cut any wires he didn't touch any wires in the dashboard." Well I didn't have this problem before I took it to you. I took it to a professional he located the burned/melted wires exactly by the engine.
I'm confused on how did this happen in the first place? I put my foot on the brake the engine cuts off and all my dashlights come on all of them. So did the mechanic mess my car up or what?
