1. I hate trailer lights
2. they never work
3. why does every trailer running lights not work
4. how do I diagnose this problem
5. how do I fix this stupid thing???!!!!!


I know it is my truck because other trucks have running lights. I have turn signals, and brake lights. Is there a fuse to just that or a bad wire or connector? It does it with the 4 pin and the 6 pin.

Had the same exact problem with mine earlier this year. It was just a bad fuse.

#5 Use Google/YouTube and learn about wiring diagnostics, get a Multimeter/circuit tester and fix it.
