I am having an issue with the brake lights. I replaced all bulbs in the tail lights and the stop sensor under the brake pedal and checked all fuses and under the hood. Still no brake lights when braking. I do have lights just the brake lights do not work. Do you have any suggestions on what the problem could be?

Thank you!

Does the third brake light work? If not I would recheck brake light switch at the brake pedal. Check for power at the connector on the orange wire and then check for power at the white wire when pressing brake pedal. If no power at orange wire then recheck fuse and if the white wire does not ge power when pressing brakes then recheck installation of the brake light switch. Hope this helps. Oh yeah- do the rear turn signals work?

Ok now im thinking the turn signal switch is bad. Hw the brake lights work on this vehicle is the brake light switch sends power out of 2 wires. One goes directly to the third brake llight and the other wire sends power up the turn signal switch then to brake lights. (Thats how the turn signals work in conjunction with the brake lights) so I think the problem is power is not transferring through the turn signal switch. You can try wiggling the hazard switch and see if that will jar the switch into letting brake lights work. Let me know

I am having the same problem that Shauna H was having. My hazzard button is stuck. If I hold it down while stepping on brakes, 2 tail lights come on. Since I can't push hazzard button in all the way (which seemed to be a fix for others), I was wondering if removing the wheel cover to wiggle hazzard switch was a simple job (one a female who has never done so could do with instruction)? I have a general GM repair manual, but it keeps mentioning using care with the air bag system. I wouldn't want to mess up too bad. Thanks!

Wiggling the hazard button is a sign of the turn signal switch slide contacts are burnt. Thus wiggling the hazard switch can lead to electrical meltdown. The only fix would be to replace turn signal switch. I know this because I actually take them apart to see what makes them work and thats when I see the melted circuitry. Im the first one who looks for the inexpensive fix but on this one its just not worth it. Hope this helps
