Do you Know the Manufacturer of the Jacks?
This is how I would troubleshoot the issue. I would get a 12 volt battery, like the one you use in a cordless drill. I would find the motor wires and hook power directly to the motor. When you make contact the motor will run one way, swap the wires and it should run the other way.If you put power to it and it will only go one way the motor is shot. I would also try to call fleetwood tech support and see if they have any input on the situation. If this was at the shop this is how I would verify if the motor is good or not.
