IMPORTANT:

Before replacing any part, clean windshield and both blades with GM windshield cleaner, P/N 1050011 or equivalent. The glass is clean when rinse water does not "bead-up" across entire glass surface. Multiple cleaning may be required to remove all contaminants. Also, clean the wiper blades by using a cloth that has been saturated with full strength washer solution and wiping vigorously. Rinse the blades with clean water after cleaning.
