Rear Wiper/Washer System

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.

The vehicle operator initiates all rear wiper and washer system functions with the control stalk of the right multi-function switch that extends from the right side of the steering column, just below the steering wheel. Rotating the control sleeve on the control stalk to a detent position selects the rear wiper system operating mode. Moving the switch control stalk forward actuates the momentary rear washer system switch. The right multi-function switch provides hard wired outputs to the rear wiper motor and the rear washer pump/motor for all rear wiper and washer system functions.

The rear wiper and washer system will only operate when the ignition switch is in the Accessory or On positions. When the ignition switch is in the Accessory or On positions, battery current from a fuse in the IPM is provided to the right multi-function switch through a fused ignition switch output (run-acc) circuit. The internal circuitry of the right (wiper) control stalk of the right multi-function switch then provides battery current signals through a rear wiper motor control circuit and a rear wiper motor delay control circuit to the rear wiper motor. The multi-function switch circuitry also uses this battery current input to directly control the operation of the rear washer pump/motor unit.

When diagnosing the rear wiper/washer system, use of a DRBIII® scan tool and refer to BODY DIAGNOSTIC PROCEDURES - PACIFICA .
