Recently mine made a decision on its own that the coach was un-level
l. It would not allow me to do much of anything, even though a bubble level said it was fairly level. what I did was unplug it from power for about 5 minutes and plug it back in and it worked as it should. The unplugging was at the panel by the drivers seat. I removed the 4 screws that holds it's down to the dash and unplugged the power. Get it a try...It can't hurt it.
