Bunk heat electric apu

[Lonestar10]

The lights are click on and switched so try pushing them up and see if their clicked off. The main bunk dome light won't work if the battery voltage low relay turns off. It's behind the cup holders on the doghouse. As far as fan/heat/cool controls on dash make sure you don't have a sleeper control button on your HVAC controls upfront. Otherwise it's a diamond logic thing and all controlled through the body controller. Other than that I would pull the peice off the passenger dash with the international symbol and clean all the fuses/breakers. Also another fuse box in driver side storage box clean those to.
