Inop ceiling lights in living room

[Barditch]

2004 HR Scepter- while parked for several days, the 3 Thinlites quit working on the ceiling in the living area. These turn on, along with the galley lights above the kitchen (which still work) with the switch in the bedroom or the switch in the doorway. Fuses are OK in the bedroom fuse panel. Suspect a relay is acting-up but don't know where it might be. Used to have a wiring diagram from the Monaco website but they have deleted it and like a dummy I never copied it to a file. Help,thanks

A 3-way switch (either switch, in bedroom or doorway) in a 12 v system takes an electronic control board to make it operate. There is often one in the circuit for more than one water pump switch. I have no idea where it would be located, but failure of that circuit board could be your issue since fuses are good.

We had mice chew up our wires in the ceiling.
