Mine is the same way. Brake lights and 4ways don't work. I changed my brake switch and still don't work. My turn signals work and lights work.

!997 Ford Thuderbird brake lights and hazards do not work


Lets start at the beginning.
The turn signals and brake lights use different fuses but both go thru the turn signal switch and use the same bulbs.
Have you checked the fuses for each circuit and does each switch have power in and out ?

Where is the brake relay on a 2000 tahoe


No relay in the wiring diagram. There is a 20amp hazard fuse and a 10amp vehicle stop fuse in the engine compartment fuse box.
If those fuses are good, and the brake light switch checks out ok, I would look at the turn signal switch next.

99 Chevy Tahoe... Rear turn signals, brake lights, and hazards


I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

No brake lights, turn signals, or 4-ways.


Did you actually check the bulbs? I believe your brake lights, signal lights, hazards all use the same bulb for each side.

Your brake lights may be your brake switch just above your brake pedal.
The signals could be your electronic flasher module (EFM) located under the dash near the steering column.
Your hazards may be affected by the EFM, but not likely and the switch for your hazards may be faulty
