Brake lights I'm kinda stumped more like frustration has taken and cant think. I have all tail light, reverse, blinkers but only the third brake light comes on when hitting the pedal. Bulbs are all good. I would think if it was the brake switch I wouldn't have the third light but I do. Its not the column switch as I have blinkers. any ideas?

The 94's have a dual pole brake switch, the yellow wire powers the third brake lamp and signals the cruise. The light blue wire goes to the turn signal switch to power the brake lights. Its still possible the turn signal switch could be at fault...more specifically the hazard switch section internally. Also the brake lamps and hazards are on their own fuse...#6 in the IP fuse block.

Seems a very good possibility. You could check the light blue wire for B+ when the switch changes state at the brake switch or use a paper clip and jump the yellow to the light blue at the back of the brake switch connector. If the brake lights work replace the pedal switch, if not you'll need to find where its being lost.

The exact same problem happened to me. It turned out to be a loose connection. I noticed after a while that the brake lights would work when I adjusted the steering wheel in a certain direction. Follow the wiring starting from the brake switch as far as possible and look for visible copper. It was just a matter of pushing a wire slightly further into a pigtail connector. I'm guessing the wire got yanked just enough somehow from my foot. Good luck.
