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?
