I don't really know what model you have, but on my coach the bedroom slides there are 2, and both are electric. The front 2 slides are hydraulic. In my bedroom one has a track, the other has cables (wardrobe). If you can be more specific maybe I can help....but first I would dig out the manuals and or look to see what you actually have so someone can give you ideas on where to look.
Is the battery fully charged and or are you plugged into shore power....could just be low voltage. What does the display show for the current voltage...?
sorry I can't be more help...
