no power to the sleeper/bunk hvac

You say you have checked the fuses but have you checked the fuse box in the cab under the driver kickpanel or the one inthe sleeper on the left side under the bunk it has five or six fuses just for the sleeper and things back under there also has some relays in to if I rembember correctly.

 

There are plugs that melt. ..Mine did anyway. ...look at the top of the right seat belt. pull the cover off for the sleeper boot. Sleeper disconnect plugs are right there. I had to wire around the plugs.

 

Is anyone aware of a documented layout of the fuse box under the driver side dash available anyplace? Got a '09 386 Pete and can't find any documentation on what each fuse is for. Thanks

 

My 2005 379 had an issue where the fluorescent light in the sleeper would turn itself on. I'd go out to the truck and the light would be on. At first I thought I was leaving it on by accident until it turned itself on in the middle of the night while I was sleeping in there. That was not a good feeling. For awhile I just took the bulbs out of it and relied on the other lights back there but they really don't put out enough light. I had Peterbilt look at it, they said it needed to be totally rewired and could cost around a grand. Eventually I found a mechanic who bypassed the switch by the steering wheel completely going straight from the fuse panel to the light in the sleeper. Works great now. I assume it had something to do with that whole two switch thing.
