do you think it can have anything to do with the turn signal switches in the steering colum....i recently had that off over the winter to install a new cylinder lock??

The brake lights share the same fuse as the hazard lights, 20 amp. If your hazards also don't work that's probably it.

To the OP, messing with the turn signal stuff shouldn't have done anything to the brake lights. Being that you said your third light still lights, I'm guessing it's the switch itself located on the brake pedal assembly. There is a yellow wire going from that switch to your third light, then there is also a light blue wire running from the switch to the tail lamps. I'm guessing the switch isn't sending power to that blue wire when you push the petal down.

I'm getting this info off my service manual for my 94. It might vary from year to year.
