Wipers

The wiper system is activated by the multifunction switch. The multifunction switch provides input to the wiper motor module to activate wash, low, high and intermittent modes. The relays are all integral to the wiper motor module assembly and are not serviceable separately.

Washers

The washer system consists of the washer reservoir and washer pump. When the multifunction switch is placed into the wash mode, the wiper motor integral electronics activate the washer pump to direct washer fluid to the windshield. When the windshield washer system is activated, the wipers will cycle 2-3 times with washer fluid followed by one final courtesy wipe a few seconds later to clear any remaining fluid that is dripping down from the top of the windshield.
