Also, apparently the stairs motor is one of a few electrical items which are connected directly to the chassis battery, and not the coach batteries. The fuse to between the motor and the chassis battery is located on a panel connected to and located on the side of the battery, which has fuses which can go blow. Tomorrow, I intend to pull the cover to the chassis battery, which is a bit cumbersome on a Mercedes Sprinter, and see if that fuse has blown. Easier and cheaper than pulling/replacing the staircase motor for sure. Wish me luck, and thanks for your advice as well!
