The windshield wipers can be operated with the wiper switch only when the ignition switch is in the ACC or ON position. A fuse in the fuse box, protects the circuitry of the wiper system and the vehicle.
Wiper blades, exposed to the weather for a long period of time, tend to lose their wiping effectiveness. Periodic cleaning of the the wiper blade element is suggested. The wiper blade element, arms and windshield should be cleaned with a sponge or cloth and a mild detergent or non-abrasive cleaner. If the the wiper element continues to streak or smear, replace the wiper blade element or arm.
