I have a problem with my 07 33DS that I and the dealer and Jayco have been trying to figure out. So I thought why not bring it up here and see is anyone has had anything simular.
The levelers, rear camera display, and electric door locks do not work on their own. They will work if I hold in the AUX battery button. These are the only devices I know of at this time, there could be more. My feeling is these are all chassis battery powered and maybe there is a grounding or miswiring somewhere that is common to these devices only. The dash lights, radio, heater/AC, lights all work fine.
Look for a battery control center. It sounds like all the coach installed items are not functioning.
On many rigs there is an auxiliary relay that powers these items. In my coach, it looks like a Ford starter relay. It may be the same as the aux start relay. It could be as simply as a blown fuse.
On my Seneca, all of the items listed get their power and/or have relays behind the drivers side kick panel, just ahead of the door, by the emergency brake pedel. It is held in place by plastic clips and there is a mess of wiring behind it.
The levelers, rear camera display, and electric door locks do not work on their own. They will work if I hold in the AUX battery button.
I would think that with this piece of information, they should be able to narrow the problem down to a few potential causes pretty easily if the right technician is on the job. I would have never thought of trying the AUX button myself.
I had a problem (self imposed) with my levelers on my 33DS when I inadvertently knocked an unprotected wire loose when sliding something in one of the pass-through storage compartments. I'm sure they've already checked those connections.
