Normal Operation
Under normal operation, the front windshield wiper motor receives power through circuit CBP45 (YE) and SBB10 (YE/RD). The front windshield wiper motor is grounded through circuits GD123 (BK/GY) and GD125 (BK). The multifunction switch is grounded through circuit GD114 (BK/BU). The front windshield wiper motor receives open and ground inputs from the multifunction switch through circuits CRW17 (GN/VT), CRW18 (VT/WH), CRW19 (BU/OG) and CRW08 (VT/OG) to activate the wipers to the appropriate modes.
