2000 Ford F-350

Certain passenger cars, sport utility vehicles, and light and medium duty pickup trucks. A switch located in the plastic cover of the wiper motor gear case could malfunction and overheat, potentially resulting in loss of intermittent wiper function, loss of wiper park function, complete loss of wiper function, smoke or, potentially, ignition of the plastic cover material. Switch malfunction is most likely to occur when the intermittent setting of the wipers is being used, or when snow or ice obstructs the blades from returning to the "parked" position at the bottom of the windshield. Loss of visibility while driving increases the risk of a crash. Correction: Dealers will inspect the date code on the wiper motor. Motors built with the suspect time frame will have the wiper motor gear case cover replaced.
