W124 - Rear Boot/Trunk Lighting Issue
When I open the rear hatch door the lights don't come on or sometimes flicker. I thought it could be a sensor of some sort or possibly the wiring harness as I heard they go bad.
I did however try the switch on the dash in both positions (Always on/Rear Door on) and the lights do in fact come on.
So, is there a sensor that could be gone which doesn't realize the rear hatch is open or could it be anything else? Rear wiper etc. still works so I assume it's not the harness? Thanks
