How Does a Windshield Wiper Work?
• • A windshield wiper is a vehicle accessory responsible for clearing, or wiping, the windshield. A windshield wiper is attached via small clips to the main windshield wiper arm. The majority of automobiles use two windshield wipers, although some exotic, high-end automobiles use one long windshield wiper for the entire windshield. • • Windshield wipers are designed to glide smoothly across the surface of a car’s windshield. Made of weather-resistant rubber, windshield wipers perform the vital function of keeping a driver’s field of vision as clear as possible during rain storms or other situations that mar, or blur, the windshield with foreign objects or sediments. • • Windshield wiper operation is controlled by the driver, normally from a switch located either on the turn signal arm or from a switch located directly on the vehicle dashboard. Most vehicles allow for different windshield wiper speeds–from very slow to very fast–to accommodate various situations. • • Windshield wiper
