Electrical Help: Brake light only works if i turn hazards on and off

i'm stumped...

both of my brake lights DO work but the left one seems to stop working for some reason. the only way to get it to work is to simply pull the hazard light button/switch to the on position then turn it back off. it works for a very short time. maybe a few miles? a few minutes? a few brakes at stop lights? whatever the case, it's not long at all.

thoughts or ideas?

thanks in advance

Sounds like a ground or a short.
Do you have trailer wiring? I do but the po had done a very shoty job of just cutting insulation and wraping the trailer wires around and re tapeing. That has sinc been fixed lol.

X2 with Rodgers. Check the tail light housing. They pull ground through the studs used to mount the housing. Make sure they are clean and making good contact.

Bit of contact cleaner into the switch might help also.

OP, have someone watch the tail lights while you have your foot on the brake. Jiggle the turn signal stalk and mess with the four way switch. I am thinking turn signal switch...

Yep, its the turn signal switch. I had the same issue in my YJ a few years ago. Replaced the turn signal switch and it fixed. The contacts are worn and, well, not making good contact anymore.
