Slides will not go out

[ehpeters]

I need some advice - I am preparing to leave for Texas in about a month and while getting the motorhome ready, it is a 2012 Georgetown XL 378, I decided to put the slides out. They will not go out nor do I hear any noise from the hydraulic system. I checked the fluid level and it was a little low so I added some ATF fluid, I checked the 15amp fuse and it is good, I checked the breaker in the battery compartment under the stairs and it is good. I started the generator and the engine, nothing, I tried to put the jacks down they work fine, go up and down with no issues, however I still get nothing when I attempt to put the slides out.
Any comments, ideas will be appreciated.
Thanks

Ok - went back to the coach after seeing note about 30amp fuse in green box. I have a 25 amp fuse in the green box, a 15 amp fuse in a blue box and a 15 amp fuse in another holder by the motor. I took each one out and checked it with my meter all were OK, however after checking and putting them back the slides seem to work - will check again tomorrow.
