Skip, On my 06 Patriot Thunder had a problem with the slides in or out, found that the connections to the pump motor solenoid were loose. Cleaned and installed tight, not problem since. I'm not sure but there must be a fuse or fuses that control this circuit. My coach has the full Intellitec system so might be much different from yours.
Yours sounds like when you hit the button the hydraulic solenoid is opening but the pump motor is not getting juice. I would start by checking the solenoid, jump it to see if the pump motor runs.
