Assuming it is the entire pad and not an individual item on the pad (you didn’t specify), I guess I’d try Steve’s recommendation regarding Lee’s method. Try placing paperboard or something along and under the cover’s edges to protect the wood against any tool. I’d expect at least a couple catch prongs that need compressing a tad along each edge of the cover, but you never know.
If there’s only one fixture on the pad not working, then check the 20 spade fuses on the two multiplex modules in the bathroom. I have a legend of what fuse goes to what, but it may not be the same on your coach.
