Question about 1994 Jeep Wrangler
I have a 94 wrangler. All my brake lights don't work. Fuse is good and I changed brake switch. Headlight/tailight, blinkers, and hazards all work so the bulbs are good too. What do you think it is?
The ground is actually connected to the brass part of the bulb. The part of the socket that touches the brass part. If you use a test light that is properly grounded and it lights when you touch it to the bump inside the bottom of the socket that the bottom (lead) part of the bulb touches, and when someone presses on the brake the test light goes on, then the socket ground is bad. I've seen tons of them completely rot off. Many times no one notices when one lamp is out 'till the other one goes out. So it may not be a wiring problem. 99% of all failures I've ever seen were at the wiring end connections, not in the long run inside the vehicle where they are well protected. Make sure there is voltage going into the switch and out of the switch when the brake is depressed. Otherwise anything you do in the back won't work.

I have not worked on your style wrangler in a minute but, from what i remember there is a main cluster of wires that lead to the back for brakes, turn, reverse etc. then it splits (i believe from the drivers side to the passenger). the harness isnt that hard to find, if you look up behind the lights/metal you will see the wires coming out the back of the tail lights. Fallow those wires to where they connect and you will be able to check the connection. Sorry i can't be so exact to where the location of that harness connection. And, i agree with "thundergod" it wouldn't hurt to check your grounds (inside the light i'm assuming he meant) but, i dought thats the problem only because (both) your lights are not working...
