High Speed
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
Test the high speed mode by connecting a separate set of test leads from the battery ground (-) post to the windshield wiper motor (4) component side pins 1, 9, and 10 (7). When these pins are grounded, the windshield wiper motor operation should now be in high speed mode.
