Starting sometime today, my automatic 1991 240 sedan is blowing out fuse 11. I never had a problem before. Okay, let's assume it is due to a bare wire on the rear defrost. But where are the wires that lead to it? And otherwise am I looking at a wire(s) around the transmission from underneath of the car? Could it posssibly an internally shorted relay?
On my '91 240, the wire running from automatic gear shift knob down to the overdrive solenoid was not very secure along the top of the transmission housing, just under the interior console. Over the years, the wire flapped around a lot, constantly rubbing off the wire insulation where it hit the tran housing, grounding out on the bell housing. I believe this was somewhat common. I cut out the worn section of wire, spliced in a section of new wire and insulated the splice, then wrapped the the run of wiring inside one of those handy protective rubber-plastic sleeves from Autopro to make sure it didn't happen again.
