Thanks Dave, I could not find it and asked one of the local dealers if I could get a copy - his response was for $175 I could get the entire book. I guess it is a trip to D-C.
Grog, I am utterly baffled about the heat and a/c on my truck. The sleeper taps off on both and I looked for the tap points yeterday in the rain and could not find them. I know that the heater valve cable need serious lube because it is binding and the vents and tubing need to be cleaned. I was told there is an intake filter but I haven't looked for it. I am planning on getting an APU ASAP and need to get that all straight.
The electrical problem has to do with the horn, it works when it wants to and I want to trace it to find where I have a broken wire. The relay is fine and so is the fuse. I have a feeling I need to just get aggrasive in my search to fix it.
I also am trying to figure out the sleeper electrical system, what a hack job that is right from the factory. The ac wiring runs through the aluminum framing with no grommets what so ever. I replaced one line yesterday because it was cut down to the bare neutral wire and the hot side was getting there, great fire hazard. Out came my gromet collection to do it right.
