The 2 lights and vent fan have no power. fuse was replaced....what to do next?

The wire for the power to everything in the upper half all go up inside a cloth tube that is parallel with the stink pipe in the back of the trailer. Check to see if all the wires appear to be in good shape and if there are any that may be disconnected somewhere.

Have you looked in the manual for the wiring diagram and the color coding? If you don't have a manual go the forum library and look for a manual for a model year closest to your trailer. There should be an electrical section that would give that information.

I would remove the bathroom lights and check for power there. Possibly a wire nut became loose causing the problem. Likewise, remove the fan trim ring and check for power there. This will give you a point to start from.
