I have two Luminas a 95 and a 96. And they both have the same problem, no brake lights in the tailights. the only thing i have is the 3rd brake light. I have replaced the brake light switches, had them adjusted, replaced the the bulbs, sockets, and checked all the wiring and made sure there was not any bad grounds. sometimes i will have the brake lights and sometimes i won't. Also sometimes one side will work and another won't. I have run outta ideas. I would def appreciate any help! thanx, Matt.

Turn signal switch. Check it too, especially if all you have is the highmount light and no others.

Never even thought of that, i'll try it, thanks.
