If the seat was turned 180 degrees recently, to accomodate visiting in the living area while camped, that may have stressed the wires in the loom underneath - been there, done that. Check the multi-wire connector(s) under the chair to make sure all wires are unscathed and solid in their sockets, and check the wires at the switch. Reroute the wire bundle so it is less likely to get yanked when the seat is swiveled.
