Washer Nozzle: Operation
WARNING: This page is about a different car, the 2006 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
The two washer nozzles are designed to dispense washer fluid into the wiper pattern area on the outside of the windshield glass. Pressurized washer fluid is fed to each nozzle from the washer reservoir by the washer pump/motor through rubber hoses, which are attached to a barbed nipple on the underside of each washer nozzle below the wiper arm. The three orifices of each nozzle causes the pressurized washer fluid to be emitted generously in several streams throughout the travel of the wiper arm to more effectively cover a larger area of the glass to be cleaned.
