Wipe-After-Wash Mode

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

When the control stalk of the right (wiper) multifunction switch is moved to the momentary front Wash position while the control knob is in the Off position, the BCM detects that switch state through a hard wired washer pump motor switch output circuit input from the right multi-function switch. The BCM responds to this input by sending a PCI data bus message to the IPM to energize the washer pump as long as the Wash switch is held closed, then de-energizes the washer pump several wipe cycles after the front Wash switch is released. The BCM monitors the changing state of the wiper motor park switch through a hard wired front wiper park switch sense circuit input. This input allows the BCM to count the number of wipe cycles that occur after the front Wash switch state changes to open, and to determine the proper interval at which to sends a PCI data bus message to the IPM to de-energize the washer pump to complete the wipe-after-wash mode cycle.
