Stop light didn't work, fuse, pedal switch - OK.

dashboard lamps or bulbs in cluster may be burnt or bad dimmer switch.for the stop lights, check brake switch located behind brake pedal

First check brake light fuse if ok Go to the brake light switch Witch is switched on or off by the brake pedal .With a trouble light check there is power on both terminals with the pedal depressed if not replace switch, if ok you have a open circuit from the switch to stop lights.

you mean brake lights stop working .check the bulbs if ok check the fuse .if ok check the brake light switch above your brake pedal.

Sounds like brake light switch is bad (little black plastic switch mounted above brake pedal below dash) common GM problem.

The flasher does not stop the brake lights from working. Check # 18 fuse in fusebox under lower left side of dash. if it's ok, the brake light switch, on the brake pedal arm is next. light green wire with red stripe is hot if fuse 18 is ok. Depress brake pedal, light green with no stripe should have power. if not, replace brake light switch. If light green wire has power with pedal depressed, combination switch under the steering is next. Remove the cover from around the combo switch {under the steering wheel}. depress brake pedal, light green wire should have power. If it does, pedal still depressed, orange with light blue wire & wire with light green & orange should have power. Those 2 wires are brake & rear turn signal wires. { The turn signal switch should be in the middle, not right position or left. while checking for power in the last 2 wires. Good Luck drvolt.

It could possibly be the actual switch that sits behind the break pedal. When the break pedal depresses or presses into the switch, the break lights go on or off. Not sure how much they run, but really easy to change. You could also check the switch with an ohm meter if available by making sure it breaks or runs continuity through the terminals when the switch is pressed/released. Hope this helps. Good luck!

if no brake lights are working,not even the high stop light in the rear window,And you have checked the brake lights fuse with a test light,it will be time to check the stop light switch located on brake pedal under dash.

CK THE BRAKE LIGHT SWITCH UNDER THE DASH, ABOVE THE BRAKE PEDAL

There definitely should be a fuse for your brake lights. It should be inside the car fuse box, but sometimes it'll be under the hood (very rare). There's also a switch above the brake pedal that turns your brake lights on. This switch may be faulty

That switch should be your Problem. Please Rate My Response! Thanks!
