1995 E300D. Somehow I managed to drop a small screw into my cigarette lighter while trying to install a satellite radio unit on the dash. Zap, out goes the lighter and radio. Easy enough fix, presumably replace the fuse...wasn't blown. Replaced it anyway. Radio works, lighter outlet does not. In addition, now the I am getting no response from the elec window controls (no issues prior to this). I plan to pull the components apart to see if I fried the cigarette lighter unit, but how would this impact the windows, and why wouldn't a fuse just blow?
