Thought I'd go ahead and put the things I've found here:
You were right on the cabinet lights. Apparently there is a ground issue though, as the cabinet lights, some light strips added inside the cabinets on door switches and the closet light are all not working. I bumped the switches a few times and they came on, then back off again. I've had the switch panel out, but it's a rats nest and looks to be power only. There is power everywhere expected, so I'm thinking it's a ground somewhere. I'll get to checking on that now that I know where to look.
Thanks Roger & Susan!
What we found is that the drivers' footwell switch seems to energize a system that interacts with the window shades. Turning it on does nothing. Turning it back off still does nothing (it's not a momentary). When turned on the second time, again nothing, but when you turn it off the 2nd time, all of the window awnings come out the right amount of distance to shade the windows without blocking the view. Then a few minutes later, they retract. I'm not sure how, but clearly this is programmed. I'll have to look into how/why it was programmed to do this, but I think the switch should be a momentary, like the hallway ceiling light. I may look at swapping to a momentary in the future.
As mentioned above, I figured out the cab and valence lights, as they did work a few times today. You were right about them...thank you! As for the kitchen valence switch, there does appear to be a LED strip tucked under the lip of the countertop that doesn't work, so I'm guessing that switch controls those. I'll get to those sometime soon too.
Keith, if I remember right, that coach came with 24vdc powered window shades operated by a multi function controller that was not working that well so he switched all the shades to 12VDC. I know when he owned it everything worked fine.
We have 6199, a close sibling of your coach so a lot should be similar.
On our coach there is a switch in the bedroom (with a key) that turns off the power to the awnings. I wonder if your on-off switch does the same. The awnings on ours go down to where the extension arms are horizontal and shut off. Does your awning remote control function with that switch turned off?
Where in the bedroom is your key? The only one I see is for the slide out control...but maybe I just haven't seen it yet.
It is on the wall. I suspect it was added later but I don't know. Ours has the east/west bed and it is on the wall above the "dresser."
To follow up, there is no key I can find besides the slide control. Nothing further with the shades either.
We found that the light issue in the bedroom was a broken/loose fuse holder at the 12VDC panel under the bed. We simply moved the circuit to an unused location and it all works fine now.
The valence light in the kitchen controls LED lights under the edge of the kitchen counters. The wire connector had come off the back of the switch. Tightened and reinstalled and all works.
Thanks guys!
