When your windshield wiper position is incorrectly calibrated, the blades will come to a stop in the wrong orientation, such as in the middle of the windshield. Your wipers may need resetting due to loosening up over time, or being forced out of position when an abnormal amount of stress was placed on the wipers, such as clearing large chunks of ice. Resetting the wipers involves removing the wiper linkage and manually placing the blades in the right position.
Remove the plastic cover between the hood and the windshield that hides the wiper motors and arms. The cover is held in place with clips. Insert a pry tool, such as a standard screwdriver behind the cover and gently twist to pop it out of place. Set the cover aside.
