The windshield washer fluid sprays from nozzles along the length of the wiper blade. You cannot adjust them. If a windshield washer nozzle becomes blocked, use a thin strand of wire to clear any blockages.

If the blade is not dispensing washer fluid, make sure there is enough wiper fluid in the reservoir and refill if needed. If this issue still persists, check the hose connection between the arm and blade for any leaks, kinks, or disconnections.
