When you say "would not operate" I assume you mean no noise, effort or anything. If this is so check the 12V fuse for the slide and the motor. The fuse is located on the 12V fuse block in the coach (somewhere). It will be labeled. There is a 20 AMP fuse for the slide and a separate 20 AMP fuse for the motor.
