Well my '03 liberty has had its first real problem. This past week both rear wondows stopped going up and down. The motors are fine. It seems that the cable that runs to the window wont catch the plastic clip that attaches to the track. Has anyone had this problem? I removed the door panels and I figure that the plastic clip is broken where it attaches to the cable or the cable cant lock into it. Can the plastic clip be ordered? Thanks for your help.
