Troubleshooting Trailer Wiring of Airstream 2017 Flying Cloud 27 FB No Turn Signal Brake Light


Just bought from previous owner. The 7 way plug had come out of his truck and dragged. None of the connectors were damaged but I just replaced because Rt. brake and turn didn’t work. Still the Rt. brake and blinker don’t work?

Sounds like the problem is further up the wiring towards the light assemblies. The most common problem is a bad ground for the light assembly so I'd check that first. A lot of times the assemblies ground through the mounting hardware so make sure the light is connected to a clean metal surface.

I attached a help article on trailer wiring for more info on this as well.
