High Speed
WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. 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 battery ground (-) post to 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.
