Check and replace bulbs. If the problem persists, either the circuit boards that the bulbs attach in, or a bad brake light switch.

Window break light good but actual break lights not working


sounds like you have a bad turn signal switch.

If the third brake light is working than we know the fuse is good and the switch is good. The third brake light bypasses the turn signal switch. If the rear turn signals are working than we also know that the wiring from the switch to the rear bulbs is also good. The brake lights and the turn signals are on the same bulb so the turn signal switch is what determines if the bulb gets power from the brake light switch or from the turn signal flasher. If the switch is bad usually the first thing that stops working is the brake lights.

Typically you can wiggle, jiggle, pull, push on the switch lever with you foot on the brake and get the brake lights to work. Sometimes turning the four way on and off several times will also get the brake lights to work. If this is the case than a new turn signal switch will solve you problem.

If you have any questions let me know!

My additional brake light is not working i have tested the brake unit and that works is there a seperate fuse for this or is it all on one fuse for all the brake lights


The third or High Mounted Brake Light runs straight off the brake light switch on the brake pedal arm. You say you tested the "brake unit"? I assume you mean the third brake light assembly, and if you get power there when someone steps on the brake pedal, then the bulbs are bad.

The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

Brake lights dont work,fuse good ,bulbs good,third light works


The third brake light switch works off a module for it is a sealed unit with a inverter that takes 12 volts beefing the voltage to 110 volts for the light emitting diode lights in it. It these terms you will need a new brake light switch located by the brake pedal

1997 gmc 3500, no brake lights, already changed the brake light switch. still have same problem. i have running lights and turn signals, and flashers. can anyone help me fix this?


Hello , do you have amber colored turn lenses or red? I ask this because maybe the bulbs are not dual filament type in the brake light socket. There maybe a brake light fuse also. Do you have a third brake light as well? Does it work? Quinn , Arizona

Main brake lights not working, third light works, turn signals work, all fuses are good, what could be the problem? 02 Olds Bravada.


Most likley the brake light switch. It has 2 different sides. One for the third brake light and one for the lower brake lights. It is inexpensive and can be changed easily. Good Luck

THIRD BRAKE LIGHT NOT WORKING


check all your grounds, fuses, just all the obvious things. If that doesn't solve it I think the third brake light is ran through your turn signal switch.

I would use a test light to see if you are getting any power back there at all first.
