Help! I'm stuck with my slides not operating - stuck out now

My jacks don't operate - the control panel lights up and will dump air, but no hydraulic operation.

I'm reading up now on how to manually pull in the slide rooms. There is a winch for the front room and the bedroom is a "push hard" from the outside of the coach.

Good times!

Thanks for the HWH link - I'm going to crawl under the coach now to see what I can find.
