Well....I am royally screwed....need advice

It sounds like your describing the Accu-Slide cable system. More than likely the cable broke and wedged in one of the pully assemblies. The motor and cables attached will be located at the top of the slide behind a valance or at the bottom of the slide close to the floor. You may have an access panel under the dinette booth.

The cable can be purchased at Amazon.com
