I change the gray panel for the taillight assembly,also checked all fuses and still nothing my third brake light works but others don't,the blinkers,reverse lights and taillights work,could this be a broken ground if so is the ground on the frame or inside
SOMEONE must have found a solution, why isn't it posted?!?!?!?!?!?!
The Trailblazer (my '02 anyway) has TWO fuse blocks. Naturally the on under the hood but there's a second on under the drivers side back seat. There you'll find the, probably blown, fuse that controls your brake lights, including your third brake light and cruise control. ;-)
Correction, this fuse shouldn't affect your third brake light, I'm sure it was already working, sorry. Good luck, hope above advice helps.
There is a SECOND fuseblock under the drivers side back seat, THERE is where your fuse is. ;-)

Had the same issue in the spring. Replace the turn signal switch. A general weakness in the switch in these years. Replacement solved the problem in my 97 Lumina.
