I ran into the same problem. All the signals, brake and hazards work but ther tail running lights do not. As I was hooking up my side markers the hot wire hit the ground causing a small spark. I took my meter and traced everything. The trailer 30 amp fuse in my fuse panel under the hood is NOT blown but I have no power to that fuse location itself?? Is there another fuse elsewhere?

It sounds like your have may have your brake light and running lights crossed on your wiring harness to the trailer. Good luck and hope this help's
