This is my own reply to my own question, but if anyone needs the info... The cable for the driver's side windshield wiper wraps around the "cam" and threads through the end of the linkage. One end of the cable is threaded with a nylock nut securing it. The "lock" part of the "ny" failed and the nut came loose and the cable became loose thus falling off the cam. This is not an easy area to reach. Removal of the drivers side dash vent and hose and the removal of the instrument cluster will make the repair much easier.
