Left Blinker/Brake light not working

[Pax84]

All my lights work besides the blinker/brake on driver side. The tail light works when headlights on and all other lights/ blinkers work. Where should I look to fix this?(My Bronco is a 1977)

I assume you tried replacing the bulb? How does it work with the hazard flashers? Turn signal switch might be a problem if the bulb works with the hazards. If not the problem is somewhere in the yellow-black wire between the steering column and bulb. A lot of early Broncos had dual exhaust at some time in their lives and that tended to melt the insulation on the stock wiring harness going to the rear lights.

My hazards dont work either with that tail light, so my problem lies with the yellow-black wire then?

Could still be in turn switch. Check wire and see if you have voltage there at the column with hazards on.

I do have voltage with the hazards on

I also ran a wire from the switch to the yellow-black wire that connected to the tail light and got nothing so does that mean the tail light wire is bad?

Sounds like it. You might just follow the wires and look for any damaged areas or places where it has been repaired before.
