Request the wiring diagram directly from Fleetwood.

Request wiring diagram(s) from the manufacturer/distributor.

The weight is about 17000 lbs.

The weight is posted somewhere in the RV. Could be on a visor, inside a closet or cabinet door, or on a door panel.

contact manufacturer they will send you a PDF file

check to see if a ground wire came loose lots of times they tie them in together

go here and find your diagram, Fleetwood Discovery 34Q Wiring Schematic Bing images

Manufacturers do not publish wiring diagrams. The items that you have described will be controlled by a fuse located in the fuse panel next to the breakers. Next you would need to determine if you have power at the switches. From there you will need to check the connections at the fixtures and try to locate the point of failure.
