Windshield Washer Spray Nozzle: Service and Repair

Wiper Arm Assembly Installation (Typical):

A correctly operating windshield wiper/washer system has a spray pattern that cleans 75% of the wipe pattern within ten wiper cycles.
If a wiper arm washer nozzle (18) becomes plugged, apply air pressure. If the nozzle remains plugged, it must be replaced.
