Well, I just bought an 03 Peter , real happy with it so far , except for one little thing. There was a switch in the sleeper , and I wondered what it did. So I flipped it. Now , none of the lights in the sleeper will come on. I flipped it back, still nothing.
I'm scratching my head over this. It's been several days now , and they still won't come on. I tried flipping the switch several more times , after first trying the lights.
Anyone else ever hear of this ?

It probably blew a fuse, what ever that switch goes to has a dead short. Just replace the fuse, and fix the short a your convenience.

I agree. I would check the fuses first. I would expect that you will find one that blew. There may also be a circuit breaker that handles the lights. If you can't find a fuse, check the breakers. You can usually find a bad one be the heat. A bad breaker will usually be hotter than the others.
