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 Wash position, the multi-function switch circuitry directs battery current to the rear washer pump/motor through the rear washer pump motor control circuit, and battery current signals are also provided to the rear wiper motor on both the rear wiper motor control circuit and the rear wiper motor delay control circuit. This will cause the rear washer pump/motor to be energized and the rear wiper to cycle continuously at a fixed speed for as long as the rear Wash switch is held closed.
