You did not indicate what year your North Point is. I would suspect that you have a Slim Rack slide. As previously noted make sure you are plugged into shore power if available. A Slim Rack slide do not have the motor synchronization feature that Schwintek does, so holding the switch for a short while when fully retracted or extended does nothing.
