Since this is happening only to one side of the vehicle and not the other than i would say you have an electrical fault in the switch and or a hot wire is broken not allowing your lights on that side to come on when told to do so.

Turn signal tail lights and BRAKE LIGHTS NOT WORKING


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.

For turn signal not working it can be faulty turn signal switch or its issue with wiring:----

Rear brake lights and turning signals not working. One tail light has been out for very long time, but brake lights and signals just stopped working few weeks ago.


I'm checking into that same problem for a early 90's buick ( it's a GM also ) , I've checked the obvious ( bulbs, flasher,fuses,etc) all where fine. I assume your front turn signals work if you manually operate the turn signal switch or put on the hazard switch? The Buick's rear lights won't come on even with the hazard switch on. When you say one tail light has been out for some time, do you mean the brake/signal light or park/running lights? The Buick was like that with one side out for a while ( brake/signal light) but both the rear park/running lights work. Now, I've narrowed the problem down to the turn signal switch. I'd bet money on it. I just have to dig out my steering wheel puller, bite the bullet and get 'er done. You should be carefull if you're attempting that repair yourself ( AIRBAG ), use a manual. ( You could do a quick test by trying the turn signal while you pull the bottom of the arm toward you,move some of the wiring in the column near the arm,etc. I did and the signals started working. Could be the switch,dirt or a broken/loose wire. there's a lot of wiring going through the column and a lot of movement ( turn signal,high beam,cruise, then add tilt) Hope this helped.

It sounds as if you have a bad earth to either one or both of your rear light clusters. If it only happens when you indicate in one direction then that is the offending side.

Running lights work but no blinkers or brake lights. Changed fuses and bulbs no luck


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.

My 2001 Buick Century's tail brake lights are not working. The far right one works but the rest dont. I just replaced all the bulbs and reset the fuses, and they still dont work. When I lock and unlock the...


Your brake light switch, which is located on the brake pedal, has malfunctioned. If you replace that your pedals will go back to working. When they go bad one or more brake lights will not work when the brake pedal is pressed but will work all other times. The reason is because the light doesn't "know" that the pedal is being pressed because it isn't getting the signal from the switch. Let me know if you have any further questions. Thanks for using FixYa!

2001 Explorer Sport ,Rear Driver Brake Light and Turn Sig. Broke


Rear lights are double filament bulbs one side for the lights other side for the brake/turn signals so it still may be a bulb. Do u have a test light or volt meter you can check to make sure u have power there when brakes or turn signals are activated. Or just try another bulb.
