Depends on what kind of slide it is. A pic would be helpful

I do believe this is a Incorrect line voltage issue. Not enough power.

Yes, all campers with slide outs have a way to manually crank the slide in/out in case of motor or electrical failure. The fun part is figuring out where exactly the place to insert the tool, if you have it. Larger slides with rails typically are brave to the main frame under the slide out whereas the smaller type (bed) would be under the bed and the false floor for protection.

Yes you would have to take off the interior slide out facias carefully then you can hyper extend the slide

Check to ensure nothing is blocking the slideout, its path or the gears of the motor. If you don't see a dimming of the lights when you push the retraction button or don't hear any motor noise check the fuse for the slideout motor. If all else fails there should be a manual slide retraction option somewhere that allows you to retract the slideout using a crank or a power drill. Check the owner's manual.

Well, take it back and do it again.
