Headlamp Washer Spray Nozzle: Testing and Inspection

Blade Wipe Pattern Check

Wiper Blade Assembly And Element Replacement

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 (12) becomes plugged, apply air pressure. If the nozzle remains plugged, it must be replaced.
