Somewhere on the inside of the slide, in one of the corners, maybe inside a bench or cabinet is a terminal block (junction) for the wiring in the slide. Remove the plastic cover and check for power there.
Be careful ... Keystone in it's infinite wisdom uses the same block for low and high voltage. If you don't have power there, there is a junction box under the trailer ... follow the wire that moves in and out with the slide. These two locations are the most likely spots for loose connections for the slide.
