Normal Operation
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Under normal operation the front wiper motor receives open and ground inputs from the multifunction switch through circuits 1301 (YE), 1300 (PK), 680 (LB/OG) and 485 (PK/BK) to activate the wipers to the appropriate speeds.
