My brake lights are not working. All other lights are working, fuses are good, and I also replaced the brake light switch. What could the problem?

I figured out my problem!
From the VERY BEGINING... I changed my brake pedal switch with a BRAND NEW switch, and the lights still didn't work.

Well, I went back down there with a live wire and touched the contacts..and guess what.. the brake lights lit up!

I got a faulty NEW brake pedal switch!! I went a year with this problem, so learn from my issue, test even your new parts if it doesn't fix the problem to completely rule it out!

I hope you guys figure out what's going on with your issue.

The Hazard warning switch is bad.

The chevys with red brake lights and turn signals do two things and I've fixeds alot of them. Looking at the tail lights with the hazard flashers on. both sides flash with nothingeles on? Or are the hazards yellow? if they're red and the third eye does work the turn signal switch is possible problem but it doesn't let the blubs and the circuit boards in the taillights out as they can fail and do some really bad stories the wires for the brakes and the turns and the hazards are the same ones and if the turns look right and the hazards look right then the turn signal switch transmites the turn too as this doesn't work part of your story can't be true

The brake lights are routed through the signal light switch.
Looks like that will be the next switch to replace and the problem.

check fuse under hood, batery terminals coroded wire at harness if everything fails run a hot wire to rear brake line with an interuptor.
check the swich under the foot brake.
