Nov 9, 2005

ON CERTAIN TRUCKS, PASSENGER CARS AND SPORT UTILITY VEHICLES, THE WINDSHIELD WIPER MOTOR MAY HAVE BEEN PRODUCED WITHOUT GREASE BEING APPLIED TO THE OUTPUT SHAFT GEAR.

Consequence & remedy

Consequence: AFTER A PERIOD OF CONTINUOUS USE ON THE HIGH SPEED SETTING, LACK OF GREASE ON THE OUTPUT SHAFT GEAR MAY CAUSE THE GEAR TO DISTORT OR FRACTURE DURING OPERATION RESULTING IN A LOSS OF WIPER FUNCTION. INOPERATIVE WIPERS UNDER INCLEMENT WEATHER CONDITIONS COULD CAUSE A CRASH DUE TO IMPAIRED VISIBILITY.

Remedy: DEALERS WILL INSPECT THE WIPER MOTOR FOR THE PRESENCE OF GREASE AND GREASE THE WIPER MOTOR GEARS IF NECESSARY. THE RECALL BEGAN ON NOVEMBER 22, 2005. OWNERS MAY CONTACT FORD AT 1-800-392-3673 OR LINCOLN/MERCURY AT 1-800-521-4140.
