1994 buick regal brake light problem

Brake lights on passenger side don't work, bulbs good, wires up to dash good(at least as far as I can trace them without tearing dash apart), need wiring diagram and/or possible cause.

I had the same problem. Your turn signal on that side I expect don't work either. I had to replace the turn sign mechanism found on the steering column. Fiddle with that turn signal switch, by pulling it toward or away from you and you should get the light to work briefly. Hope it helped.

this might help you if you need to change the turn signal Switch.(wich is prolly ur problem)
