Wiper Blade: Description and Operation



The wiper blades are a rubber element with a steel vertebrae that are mounted on the end of the wiper arm and sweep across the windshield to clear it of water, snow and debris.

When the wiper blade rubber element is exposed to the weather for a long period of time, it tends to lose wiping ability. Periodic cleaning of the wiper blade element is suggested to remove the accumulation of salt and road film. The wiper blades, arms, and windshield should be cleaned with a sponge or cloth and a mild detergent or non-abrasive cleaner. If the wiper blades continue to streak or smear, they should be replaced. The driver blade element is 600 mm in length and the passenger blade element is 550 mm in length.
