I'm assuming this is an electric slide motor?
If so, start the engine and try to bring in the slide. The extra few volts from the running alternator can be a big help to that motor as it tries to lift and move the heavy slide.
If that works, then I would do some snooping and look for loose/burned grounds and/or power wires. It could also be a sign that your batteries are getting old or require some maintenance.
Good Luck,

If it's electric it depends on how it's wired. Our slides won't move when the key is turned.
