Try going to a junk yard and getting a BCM (body conrtol module) for about $35 and replace yours, just make sure that you have the same part number as the one on yours. The BCM I slocated under teh dash on the far driver's side on the bottom, there're 4 screw holding it in after you take off you lower molding. This is a typical cause of Grand Cherokee window issues. If it was a frayed wire, you would have blown a fuse OR only one window would stop working, not all of them.
