Brake blowing fuses, Any ideas?

1994 GT

Okay I decided to start a new thread since it has been a few days and the problem has been narrowed down a little more. After spending a day tracing wires and fuses I have come to realize that my turn signals were not blowing fuses. Whenever I press the brake pedal it pops the fuse that controls the turn signals/hazards. The running lights / rear tail lights and blinkers work with a new fuse but the brake light does not (they short the circuit). We noticed the sockets for the license plate where both melted/corroded however we bypassed the sockets and the brake is still blowing fuses. We then disconnected the tail light assemblies from the harness on the rear in case it was a tail lamp or bulb causing the short however there was no luck, it was still blowing the fuse. Any ideas on what else to check?

The wiring for the brake lights probably runs down the driver rocker panel (if you pull the door sill trim off, you can pull the carpet up over the clips and see a bunch of wires down there). Trace wires and make sure the wire did not short to ground.

FIrst though, I would look at the switch itself (on the back of the brake pedal arm). It may have somehow taken a dump (though I am not sure how it would to short to ground). I would hate to not say to do that since you have to rip up a fair amount of stuff to check that brake wire.

Maybe Shane or someone else will have better ideas.

Good luck.

those brake light switches are so cheap u can get one just to see if it fixes your problem, if it doesn't just return it and tell them it was the wrong one.

Yeah I was looking at that switch yesterday. Still trying to figure out how to take the damn thing off. lol

there is probably just a hitch pin holding it to the pedal, if the fuse keeps blowing for the brake lights what u could do is just unplug the switch and see if the fuse blows then. if it doesn't then i would say the switch is no good, if the fuse still blows then something else on that circuit is the culprit.

Follow Up?

Hey, did you guys ever find out what was causing the fuses to blow?
