Chosen Solution
I have a 1998 Chevy Camaro. My 3rd brake light works, hazard lights work, signals work and tail lights work. The problem is the lower brake lights! Bulbs, fuzes, and switch is good.
Do you have the correct bulbs installed, look at the tips of the bulb for one or two contacts and be sure the bulb socket has the same type. Play with your turn signal switch a little, possibly wiggle it very little, have seen a short kill the lower brake lights, you may also have an electronic brake light module, sometimes they get full of water and completely rusted out, may be there in the trunk, follow the wire harness along until you find a broken wire to ground, or power wire broken or the module. Step on the brakes when playing with everything to see if it will act up for you, good luck.
