brake lights?
Hello! 87 Bronco, and the brake lights don't come on when pedal depressed. All other lights work, turn signals, hazzards and all above when the lights are on. Look at the diagram on the fuse panel cover find the fuse and it's blown for the brake lights, hazzards? Replace 30amp fuse hit the brake pedal blown again. All the other lights that go trough this fuse work though.
I know that the brake lights run through the blinker switch for timing purposes (bulb filament?) question, could it be the flasher switch? My girlfriend wrecked into someone around christmas and it knocked the truck so senseless that it killed the starter. I thought it might be the cylinder lock so I got in the steering colum to take a peek because the lock was hard to turn anyway and I assumed it was that. Starter in, and ever since then truck is fine every single light works except for the brake lights.
Thanks in advance for any suggestions!
Regards,
Nate

If you want to keep from replacing fuses all the time, rig up a 12 volt bulb or test light so that it will plug in where the brake fuse plugged in. Wire the light across the terminals, and when the pedal is pushed, if the light comes on bright, you know you still have a short. If it comes on dim, you have it fixed.
You are going to have to trace the harness, because obviously you have a wire rubbing metal somewhere. I would unplug the steering column harness and see if the short goes away, If it doesn't, I would suspect the high mount third light brake wiring. If the short does go away, then I would follow the harness along to the back. I am not sure if the rear brake wiring runs along the frame like a truck, or runs along the door sill under the carpet like a car.

Thanks, Turns out I assumed that the fuse was blown the second time, when I had the chance I got under the dash and noticed that one of the two wires on the actual brake switch near the pedal was unplugged.
One of the easiest repairs on that truck in years! Thanks again.
