Which slide and what is the year of your coach.
Your the first I have heard that a slide wouldn't move or just grunt. Its maybe something simple like a loose ground wire or dirty connection. If you know where your control units are unplug the plugs on ckt board and reconnect. Check wiring to motor inside of compartment to make sure your didn't brake a wire to it when loading something in the compartment. If its the bedroom slide do the same and check wiring to motor.
