If the motor does have power and the switch is "known good" then check the battery for a full charge/good wiring connections and check the converter for blown fuses. Be sure to also check the two red reverse polarity fuses. If all of that is good, then I'd suggest looking for one of these "auto reset circuit breakers" that has likely failed..... Usually they are located on the tongue/in the front storage compartment.....
