No brake lights!

Fuses good
Brake switch good
blinkers work
Parking lights work
Reverse lights work... what gives? Secret fuse or relay?

Thanks for any hints

How do you know that the brake switch is good? Have you checked your ground wires? Have you checked your bulbs?

Took it out and tested with a multimeter.
Haven't checked all of them, locations?
Both bulbs are good, blinkers use the same circuit.

Is it the right light bulb. I've seen people stick a 1156 in a 1157 socket and it won't work becouse the 1157 is a dual filament bulb and the 1156 isn't.

The turn signal switch may be bad even though that the blinkers work because Mother Chrysler used to wire the brake lights through the emergency flashers years ago.
I'm not sure if that was still the norm in the 90s.
Just for the record, I've replaced two turn signal switches in the past when I had brake light problems and that is what solved my problems.

Had the same issue a couple of weeks ago during reassembly of my 92 yj after bedliner install. Basically the brake switch can and will give you a false reading. While installed no brake lights. When removed from jeep switch was working. I did find in my trouble shooting a fuse that was loose because some where in this jeeps past somebody thought out was a good idea to jam something into the fuse block. Fixed that issue and reinstalled brake switch. Brake lights work however, now sometimes they will not cut off. Brake light switch is sticking. Just my 2

Do you have power going to the switch and back out? Check using a test light. I've seen switches test good with a meter, but the contacts can't pass enough power to light the lights. The meter doesn't put any load on the switch. Next, just follow the circuit to the turn signal swtich, checking connections and wiring.

Did you pull the housings off of the tub and check the mounting screws for rust?
When I had issues with my brake lights, they were doing all kinds of strange things, it ended up being a bad ground connection (stock lights use the mounting screws to ground to the tub).
