First time trying here. Hope y’all can help me.

My my lower brake lights aren’t coming on. Running lights are fine and top light is fine. Just the bottom 2.

Ive checked bulbs and fuses, and replaced the switch in the back by the fuses. Still not working. Any suggestions on what could be the culprit?

 

I'm Sorry - don't understand your question - There are only 3 brake light bulbs - 1 on each side and the center bulb - exactly what is not working that you want to work? Do you want the rear fog lights to come on with the brakes? If you are talking about the bulbs in the bumper -those are either a parking light or a fog light depending on the year.

 

The side ones. Only the top is not illuminating.
