Rear LED tail light not getting power

Recommended Posts

The LED tail light on my 2013 R/T recently stopped working, driver's side only. It's the inner one, the one on the lift gate (the outer one, which is the brake light, is still working). I took the tail light assembly off, and tested power - there is no power coming to the light. Manually ran power to the light, and it lights up - so the light is good. Even stranger, when the headlights turn on, the reverse light on that one side also comes on, unless you open the lift gate and then the reverse light goes off as long as the gate is open.

 

Any ideas on what is wrong and/or how to fix it?

I lost the same light on my 14 R/T, I also lost the parking light and the signal light On the drivers side. The break light works fine though. I pulled the light assembly out and put a new signal bulb in, hit the lock button to see if it would flash and it didn’t BUT the parking light flashed quickly and then wouldn’t come on again. I tried several times again without it coming back on. I took the light assembly back out and moved the wires all around and still couldn’t get it to do it again. Any ideas where to look for bad wires, bad connection or something else?

See above comment.  Wire loom at the top of the gate going into the body

 

So what your saying is that the wire harness goes from the right side, up over the top to the left side? Just trying to make sure I understand fully.

 

how would I get to the harness? Is it accessible from where the gate opens? Do I have to drop the ceiling panel? Any help would be great, thanks!

 

thanks for your time and have a great day!

Just look at the harness. Cut the loom open or untape it or whatever. The wires are inside. You need to inspect them.

Ok great, thanks for the info! Any idea how I get to the loom? Is it in the roof and I'd have to drop the ceiling panel? Or is it accessible by opening the lift gate? Any help would be great. Cheers!

See the above response. Open your lift gate and look.....

I've cut open the loom. Took the tape off of the wires, dropped the liner panel and inspected all the wire run, I don't see anything wrong with the wires anywhere. I've even removed the gromets and looked at the wires there, still nothing. Any more idea on where to look or what could be wrong? Anyone know where I can find a wiring diagram?

So I found the problem! It was not in the wire bundle that passes threw the body up by the lift gate. It was a faulty module that controls the wiring for the trailer hook up. It's tied into the left break light assembly. It has a "T" style harness for the break light and the park light and then is spliced into the signal light. The module is tucked in behind the bumper just below the tail light assembly. I removed the "T" connector and cut the wire for the signal light that was jumpered from the car harness and went to the module. It didnt work right away, but not untill i cycled the car ignition to the on possotion without starting the engine. I'll post pictures when I go back in and clean the area up
