left tail light not working, replaced tail light, did not help?
left tail light isn't working there is no power to it but the turn signal and brake still work and it interfiers with my trailer lights
Not fixed. Right tail out. All other functions good (turn flash ). Bulb good. Good fuse. No brakeLights. Left tail good.

Tied into ieft tail if needed for night quick trip.
Tail lights no longer working but everything else does
Ground wire in the wiring harness was said to be the issue. Brake lights would b\not work if the headlights were on. I replaced both rear wiring harnesses to the stop, brake and tail lights.
Everything was good. Online prices were $33.00 per harness.
I keep burning my fuse on my right stop light. I changed the trail plug recepticals and the wires for the one inside the bed but it didn't help. looking for any suggestions
