Normal Operation
WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
Under normal operation the rear wiper motor receives power through circuit 406 (BN/WH) and circuit 1002 (BK/PK). The rear wiper motor is grounded through circuits 1203 (BK/LB) and 1205 (BK). The rear wiper motor receives open and ground inputs from the multifunction switch through circuits 410 (WH/OG) and 411 (BK/LB) to activate the wiper to the appropriate speeds.
