Had the same problem with our slides on 2007 Georgetown 340 this spring. After checking all fuses and circuit breaker three times, I was going to bring them in manually with a ratchet, while the hydraulic access was open, jiggled all the wiring to the motor and the slides came in and jacks worked, both were dead. I cleaned the connections and tighted better when we got home and everything is working fine since. there is a big relay in front of the motor with several connections, that is where I found the culprit. good luck.
