There are various interconnected devices that interact with the slide control that could cause that to happen.
I have a 2002 Windsor with three electric slides.
If the key is on, the slide control will not work.
If one of the strorage bay doors directly under the slide are open or the bay door switch is mis-aligned the slide control will not work.
The bedroom slide is not affected by the storage bay doors.
Also, if the 5 amp fuse on the Slide-Out Control Board is blown, the slides won't work.
You have to start a trouble-shooting plan and start checking off one at a time until you find the culprit.
If your slides are all hydraulic then someone else with hydraulic slides will have to chime in with some suggestions.
