I discovered a few days ago that the break light on the drivers side was not working. I replaced the bulb with a 3157 per the owner's manual, but it still would not work. I pulled the same bulb from the passenger side to make sure it was a 3157 (which it was) and then replaced it. Last night I discovered that I had not tail lights or break lights on either side. The turn signals work and the flashers work. I've checked fuses, but can't find one that seems to be burned out. Any suggestions?
Look up "fix jeep brake lights". I had a similar problem and just had to bend up the little metal contact tabs on the brake light assembly using a small flat head screwdriver-they were not contacting the bulb well. Took a whole five minutes and all is well.

1) Open trunk
2) Remove small round plastic access panel with a flat tip screw driver by prying open
3) Remove flat tip screw holding tail light assembly
4) Remove tail light assembly by pulling outward, careful not to break plastic guide/nub
5) Disconnect wiring connectors
6) Remove plastic housing access plate on back of tail light assembly by twisting/turning tabs until they click and then lift access plate from tail light assembly
7) When viewing the the bulbs, the turn signal bulb is the bottom left bulb
8) Install in reverse order, ensuring tail light seal seats properly during installation
I believe this car has a bulb with two fillaments for side and brake lights, it is unlikely that they are both burnt out at the same time but possible. It is more likely that the bulb holder or a ground connection is rusted or loose. The fuse generally covers all rear lights.
Almost always, your described concern indicates a loose ground particularly on the driver side. What is required is to check the connectors leading to the driver rear side and/or a ground wire. Often, the problem would be the ground terminal is loose or corroded leading to the body of the vehicle. A temporary workaround is to determine which is the ground in the bulb socket (always the body) and wire a jumper wire to any exposed metal part of the rear end.
I had the same problem. Check the fuse to the brake light switch (I'm pretty sure that's what it's called). Chances are, that's blown and causing the lack of taillights. As for the single light going out, me and my dad just fiddled with the electrical contacts on the bulb housing until we got it to work. Basically just bent them up a little bit so we were sure that when the bulb was installed, it definitly made contact with the metal tabs. Sorry I can't be more specific.
If the driver's side tail light is working, it's not a fuse. Use a test light to check for power at the bulb holder. One terminal will be for tail light, the other for brake/turn light. If the is constant power for tail light, replace bulb. If no power, trace wiring from bulb holder to driver's side junction. Probable broken wire between the two tail lights.
