6 Point Leveling

Hey guys I have a Durango Gold 380FL that I've been camping in for about 6 months now. My last camping trip was about one month ago. This week I attempted to hook the camper up to the truck to move it. Upon doing so, I ran into a problem with the hydraulic jacks. This camper has a 6 point leveling system on it. When attempting to raise or lower the jacks, they won't move an inch. The control panel is on and working, but the jacks do not respond. I have checked all fuses and all seem to be intact.

Any troubleshooting ideas from people who have similar setups?
