So does the green AC light come on when you push it, but won't stay on when you let go? mine has done this several times, I found if I push and hold it in for a slow 3 count it stays on when I let go. Only does it once in a while. We have had a dozen issues with our Alante, nothing like you, we did have the bunk rail pull loose on the passenger side, I fixed it by fabricating a bracket that screws into the side wall and prevents front to back movement. Now the left side is coming loose so I will have to do that side. Other that that I have fixed all the issues myself as the dealer is useless. I did get some help from Jayco CS on parts I needed.
