Wash Mode

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

When the rear washer control switch is depressed to the right in the momentary Wash position, the instrument cluster sends an electronic washer switch message to the FCM, then the FCM directs battery current and ground to the washer pump/motor. This will cause the washer pump/motor to be energized for as long as the Wash switch is held closed up to about ten seconds, and to de-energize when the rear wiper/washer switch is released.
