Passenger side marker not working
I've been racking my head on this one for a little while and haven't been able to find a solution.
My passenger side marker is out, but the turn signal still works (flashes with hazards too). I checked the fuses and all seem to be good. I've replaced the bulb (maybe one filament was burned out) but that didn't work. I replaced the socket itself as well, and cleaned the connections.
This issue is really starting to bug me because I want to add fog lights but it would look dumb with one side marker out.
It's a 97 Mustang v6, but with a 95 5.0 HO dropped in (95 pcm and wiring harness). I don't recall, but I believe I reused the 97 harness for the headlights. I do know that this issue has gone on since before I did the engine swap.
