I have a 2013 Acura RDX and only one brake light is not getting power, my passenger side brake light. The only fuse I found is is good, bulb is good, and the bulb socket is good.
i stripped the wire itself back and confirmed no voltage on the wire itself.


I need to find where the wire junctions so I can test continuity on the wire and trace the problem back from there. Any help would be greatly appreciated.

 

I would just start following the wire loom up the lift gate and you'll probably find your culprit. wiring harnesses and moving liftgates/trunk lids typically lead to some broken wires in there. You won't have to go very far.

 

Does the wiring go up and over? I thought it went down and over under the spare tire hatch. It’s hard to see because the speaker has to come out to see where the wiring runs.

 

Sorry, i read tail lights, didn't realize the 2013 RDX's brake lights are actually on the body. you'll need to follow the wiring either way.. a wiring diagram won't help in that case :/
