Hello, i looked at the fuse diagram and the # is 25 the options on this fuse are: turn signal, fanfare horns, backup lights, and automatic transmission. now i had a neighbor look while i put car in reverse and the backup lights are not working either. so i unplugged all the lights and horns it still blew the fuse. as far as the transmission i don't know where to start with that. does anyone know of a free wire diagram web site? or where the turn signal relays are located on a 93 500 sel?
