Our 2015 28.5 RLTS Eagle fifth wheel had the same problem that the OP has. We (service tech) took the switch off the wall it was mounted to, and connected the wires as it said to on the back of the switch. Jumper on the power center had been removed already. Works as its supposed to now. Can't help but wonder why it was not caught before we bought it. The switch looks like the one pictured, red and a 90 degree throw.
