I think you have a switch problem. See if you can spray all the dash switches with that Dry Lube they sell these days. I use it for my slides and my basement locks. It's thin enough that it gets into things pretty well. Switches for instance. But it's lubby enough that it works on the slide rams and the leveling rams too.
