It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

These will help.

Thanks.

sihelp megnals do not work car will not start with key i jumped starter with screwdriver started right up

I'm inclined to believe it is the turn signal switch. When you select left or right, the brake light is removed from that side, and the flasher is connected to the bulb instead, making the brake light on that side flash as the indication that you plan to turn. You have lost everything, but the simple answers check out.

If you have lost signals, brake lights and tail lights, then it is more likely that the ground supplied to the bulbs is not working, since the tail lights share noting in common with the brakes lights and turn signals but ground.

If the tail lights work, the fact that the brake lights and rear turn signals share that switch starts to look meaningful — even more so if the front turn signals also don't work. But the front signals and the rear signals use different circuitry in the switch, so it would be something more mechanical in the switch than electrical in that case.

could be brake light switch but i would be more inclined to think the signal switch is bad, the brake light circuit goes from the pedal to to the turn signal switch then to the taillights

Could be a fuse or relay..
Or try replacing the break light switch..
Its located on the break pedal brace just above the break pedal..

Hope this helps !!
rate me good ;o)

I had the same problem about a month ago myself. I had to replace a fuse which was under the driver side under the dash it cost me $6 to replace. I cant remember the name of the part but call a auto store and explain to them the problem. I think it was called a relay fuse or something! Good luck with that!

possible short in wiring

i had the same problem had to replace the turn signal switch....GM for some reason wired the brake lights through the turn signal switch. to check if this is the case with yours. put some pressure on the turn signal lever as if you were going to turn on your brights and press your brake pedal and see if the lights work at that point that is how i found mine. hope this helps. if indeed they work with pressure on the turn signal lever. the new switch cost me $60 at autozone and that is with the steering wheel radio controls, make sure you get the proper switch should be part# sw771 if you have the radio controls on steering wheel and you will need a steering wheel puller and lock plate compressing tool.

check the fuse for the stoplights. Even though the 3rd one is working it should be on a different fuse. With both of them not working even after you changed the bulb it would seem to lead to a fuse.

my tail lights on a 2002 buick regal do not go on when lights are on, I changed a couple of the bulbs still nothing, brakes lights and backup lights work.... also the inside dash lights do not work could it be a related problem,
