My 1979 Tr7 has blown the wiper fuse a couple of times in the last month. This circuit also controls the brake lights and blinkers. My problem is I replace the fuse and can find no issues and then a couple of weeks later it pops again.
It does not seem to be tied to wiper/washer use so i am guessing that it is the brake/turn signal use that triggers this. I have looked at the wiring in the trunk and near the wiper motor and under the dash as well as the stop light switch but can see nothing obviously wrong.
I replaced the fuse again yesterday and cleaned all the light bulb bases in the trunk. So far it is working fine but I have only driven the car about 20 miles.
I am at a loss. Anyone have any experience or thoughts about this?
