I have a light out on a portion of my quarter panel mounted tail light on a 2014 Fusion Energi. It's just on one side. It's the running light. The turn signal works fine. I bought a new led light assembly thinking that the board had gone out inside the assembly. But the new light does the same thing. Any ideas what could be wrong? I can't find anything about light fuses in my owners manual. The harness looks ok.
