205V520000 · Visibility:windshield Wiper/washer:motor
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.

Jul 6, 2005
ON CERTAIN SPORT UTILITY VEHICLES, THE FRONT AND REAR TIRES ON THE DRIVER'S SIDE OF AFFECTED VEHICLES MAY HAVE BEEN DAMAGED AT THE CENTER TREAD DURING PRODUCTION.
Consequence & remedy
Consequence: OVER TIME, THE DAMAGE MAY BE SUFFICIENT TO ALLOW BELT CORROSION ULTIMATELY LEADING TO A TREAD SEPARATION, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT ALL FOUR TIRES (TO ENSURE INSPECTION OF THE LEFT HAND SIDE TIRES THAT MAY HAVE BEEN ROTATED TO THE OTHER SIDE OF THE VEHICLE) FOR TIRE TREAD DAMAGE AND, IF NECESSARY, REPLACE THE DAMAGED TIRE. THE RECALL BEGAN ON JULY 13, 2005. OWNERS MAY CONTACT FORD AT 1-800-392-3673.
