What if 1994 suburban brake light not working?

Answer 1

AnswerIf only 1 light out check bulb and socket If all out check fuse and stop light switch

I have the ANSWER for BRAKE LIGHTS NOT WORKING on 1994 Chevrolet Suburban when all other remedies FAIL! My experience went through every part replacement I could think of, Bulbs, new tail light circuit boards, relay, in dash head light switch. Even had a mechanic tell me the problem was going to be in the steering Column wiring harness which connected to all of the other electrical areas of the truck. Made sense and there was a ribbon of about 20 wires heading up the column from under the dash. I'm getting 12 volts at the rear circuit board contacts when I press the brakes but no BRAKE LIGHT! So after the mechanic broke my steering column replacing the wiring harness, I still had no brake lights.

Description

VEHICLE DESCRIPTION: PICKUP TRUCKS, CREW CABS, UTILITY TRUCKS AND SPORT UTILITY VEHICLES. THESE VEHICLES WERE BUILT WITH THE POLARITY OF THE WIRING FOR THE ZERO ADJUST BRAKE SWITCH REVERSED FROM WHAT WAS SPECIFIED ON THE SWITCH DRAWING. WITH THE REVERSED POLARITY, THE CONTACTS IN THE BRAKE SWITCH CAN WEAR OUT PREMATURELY. THE BRAKE SWITCH WILL PERFORM NORMALLY UNTIL THE BRAKE SWITCH CONTACTS WEAR OUT, RESULTING IN LOSS OF THE BRAKE LAMPS WITHOUT ANY WARNING TO THE DRIVER.

Consequences

THIS WOULD FAIL TO WARN A FOLLOWING DRIVER THAT THE VEHICLE IS BRAKING AND COULD LEAD TO A CRASH.

Corrective action

DEALERS WILL REPLACE THE BRAKE SWITCH AND REVERSE THE WIRING.

PS - Columnsgalore.com saved me with a rebuilt column after mine got messed up by the mechanic.
