Electrical problem

Hi all! I have a 2004 Jeep Wrangler Sport. My problem began about a year ago when my left rear turn signal light was dim and wouldn't flash. The clicker inside was flashing rapidly. I thought it may be the ground so I ran a wire from the left taillamp screw to the body. The problem was intermitant and stopped for some time. It just recently started again and then moved to the right rear turn signal as well. I now have no rear lights at all. No brake lights, no tail lights, and no turn signal lights. All my front lights work. If I turn on my emergency flashes, they work but are extremely dim in the rear. All fuses are fine and bulbs. Anyone with any ideas before I head to the dealership to get raped? Thanks.

Check the sockets at each signal- the 2 in your front fender flares, and the 2 on the front corners. Pop the bulbs out and look into the sock. If you see that greenish-blue electrical rust crap, that may be the problem. My front left socket in my fender flare was all corroded and was causing serious blinker issues. I popped it out and replaced it and everything was good. I would by dielectric grease as well and put a dab in each of your sockets, then press the bulbs in- it keeps moisture out of the socket connection and may prevent this from happening.

Thanksall. All the sockets are clean, all the bulbs are good. I ran another ground and still nothing. Tried to get a flasher unit from Checkers. Of course, its the wrong part. It goes into the dealership tomorrow. Im betting its the flasher but Im sure they will come up with some BS story about having to run new wires and charging $1,000 or so. lol. Ill post what they say. Thanks again for trying to help!

I had the same problem and it was an easy fix once it was figured out. My problem was in the tailgate connections to the spare tire brake light. When you open the tailgate look for the wedge in the door and two round contacts on the right trunk wall. Inside the wedge on the door (near the hinges) are the other two contacts that make the connections for the spare tire brake light to work.
Check to see if the contacts are connecting. I had to take the wedge on the tailgate off and shim the contacts a little higher so they made soild contact. Now everything is good as new. It was a bitch to find, but easy to fix.

Good luck and I hope this helps.

Thanks Zonker. I wonder if that has something to do with it. I don't have the third brake light anymore. It wouldn't fit with the 33" tire mounted on the rear so I removed it and it's wires. Anyways, it went to the dealer. They said it was the ground. They also said they fixed it. Everything works now except when I have my headlights on and use the right turn signal. Then it all goes crazy. The rear lights dim, and both lightly flash. The front right signal flashed rapidly. Back to the dealer again today!

Okay, it was the ground AGAIN. The nice Mr. Dealer charged me $111 the first time to repair the ground that he didn't correctly repair. Then another $56 to fix it correctly the second time. I wouldn't recommend Centennial Lithia Jeep to anyone.
