ok heres the deal, i just bought a '88 GMC JIMMY. all the lights work, headlights, interior, park lights, tail lights, reverse lights, license plate light and Turn Signals, BUT no Brake lights. Ive checked the wires running up the frame rail and they appear good. the bulbs are good. the wires running into the light housing seem to be good. the wires running to the headlights, park lights up front seem good. I replaced the stop light switch under the dash and still nothing. Is there a 2nd fuse for the just the brake lights that i missed, i only see taillight assy fuse. that is good. only other thing i can think of is something with the wires behind the dash. Any suggestions would be greatly appreciated.
