Glad you got it.. that's frustrating.

Garyk x2 on the fuse, it could be corroded. Also use a 12 volt tester and see if you getting current to the brake switch.

sevenservices Could be the connectors behind the lights. I ran into this on my YJ, pulled the covers, wiggled everything around, been good for six months... Happens to the headlights a lot as well. Before buying headlights for a YJ, check the connections

I will say this about the fuse...

thanks, I'll give it a shot. Can't hurt anything.

PTaylor Yeah, the brake pedal switch has already been replaced. I was 100% sure that would have solved the problem, but now....

There's something common that isn't allowing the lights to come on. I just can't find anything else to check other than start tracing wires throughout the whole thing, and I really don't want to do that.

drivebytruckerz You already replaced the little white button looking switch behind your brake pedal? It's like a white version of the switches that cause your interior lights to come on/go off when your doors are open/closed...

PTaylor thanks for the response.
Isn't that the same as the brake switch or is there another one? i replaced one switch already.

AfterMath Did you check the switch by the brake pedal? Maybe its not engaging?

Edit: I suggested something that you checked, woops.

No brake lights?

This one is making me ponder. I've got a YJ sitting in my yard with no brake lights. The fuse is ok and getting voltage. We replaced the brake switch, still no lights. we checked the bulbs, they are ok. all other lights work, hazzard, turn signals, night, just no brake lights. The vehicle hasn't been modded so the wiring is original and in the original location, and I've been looking at that but can't find anything obvious like broke wire, broke connector, etc. Only other thing I know is to start tracing with a volt meter but thought maybe there's another component like a relay or another fuse that I need to check first. Anyone got any advice or seen something like this before?
