To help you more, I will need to know if you have a Wrangler, Cherokee, or Grand Cherokee. It sounds like you may have a possible ground problem or a bare wire rubbing, first location I would check is the junction where all of the wires plug in the back, Also, one of the leading causes to your problem is the trailer light plug harness or the plug itself shorting your system out, try removing the trailer plug system on the back and isolating the wires and see if this helps.

It is a 2000 jeep grand cherokee laredo
i have checked for bare wires in the back and see none.
I dont think there is a trailer plug harness.
Not that I know of anyway.
Pretty sure its a ground problem so I tried running an extra ground from the black wire to the frame and that shorted out every light on the left side.

Did not yet get this resolved.I tried 4 or 5 different things, i.E. Running a new ground, replacing wires, checking connections. No luck with anything. I have given in and am taking it to a repair shop tomorrow.I will let you know the cost of this repair after I have it done.I just had the relay to the rad fan go as well. They come in 3's so now I am just waiting on the next thing. Good luck!
