I have no brake lights or blinkers on the rear of my 1989 Jeep Wrangler. I had one left blinker in the rear but not now. Both blinkers work fine on the front. I tried grounding the rear lights straignt to the battery with a long wire and nothing happens. I replaced the turn signal switch and nothing happened. I got a test light and get no power at light. I followed it to the connector near the fuse box and still cant get power. All my fuses are good. What can I try next????
All grounds look good that I can find. Blinkers work coming into firewall. They meet up just before the plug that goes to the connector where wires go to back of vehicle. I have no power at connector. Wherever they go between the two Im losing power. I replaced the turn signal switch and that didnt work either. I still have no brake lights or blinkers on rear of vehicle. What else can I try? Its got to be behind the dash somewhere.All grounds look good that I can find. Blinkers work coming into firewall.

Should still be under warranty. If you have determined it is not a burned out bulb, let the dealer trouble shoot.
Some other things to check, from a wiring standpoint, does the right side emergency flasher work? Does the right side backup light work?
If these do not, I'd look for a connector to the right side of the rear that came loose. Haven't spent that much time under my 2009 (same model style), but I'd suspect on a jeep that physically following the wires to a connector would not be hard. Also could be a ground issue to the right side lamp housing.
I used to have a 98 wrangler, I had a problem with the brake lights at one point and found that it was do to the blinker switch! This was a little bit of a project to replace it. Steering wheel had to come off and steering column comes off and the whole blinker switch is one piece.
All tail lights in the 98's goes through the blinker switch. I am not saying this is your issue for sure! But it sounds like it.
The problem could be the wiring connecting to the lights, you need to check them for bare wires. Look them through for any metal hanging out of the rubber insulation. You may need to get new wiring.
