I have a 2022 Western Star 4900SF Car Hauler.
None of the lights in the sleeper will come on all of a sudden with neither the switches nor when the door opens as normal, so I’m sure it’s a blown fuse somewhere.
I checked the main fuse panel on the passenger dash, but the only fuse for sleeper in there is for the charging port and it works fine.
I googled and you tubed, but nothing there. Seems a lot of people have the same issue locating the fuse box for the sleeper. Some of the 2015/2020 models have a sleeper fuse box under the bunk, but this model doesn’t.
I even called a few dealers, but they were no help. I was hoping maybe someone here ran into this issue before and could point me in the right direction.
Thx in advance
