Brake Light Help-77 FJ40 (1 Viewer)

My brake lights recently quit working.
I replaced the switch and still no brake light.
Checked fuse and it is ok.
Running lights are functional.
Just checked the hazard lights and they are not working either.
Any thoughts appreciated

Have you checked for a burned out bulb?

have you checked wire continuity from the brake light switch on the pedal to the light socket? The hazard light uses the same filament on the bulb (same wire)

Jason, what was the issue with your fuse block?
I have the same issue and my fuse block looks good. I just soaked and cleaned it.

I had the same problem. Wiring, fuses, everything tested fine. It ended up being the small relay next to the ignitor. It has three wire leads that run the signals / flashers. I cleaned the contacts and everything was back in business.

My 72 doesn't have an igniter, but I'll look for the relay. Thanks!

Here's a couple of pics. The connector with the green wire leads was the culprit on my 77.

sorry for the delay. it ended up being the contacts on the fuse block. i roughed them up with sandpaper and that resolved the problem.

Same for me. After a good cleaning and all new fuses, everything worked as intended.
