A windshield wiper in a vehicle performs the function of cleaning the windshield from water, snow, and dirt. A properly functioning windshield wiper is very important for safe driving, as it allows you to keep an overview of the road in front of your car. In some countries, the law prohibits the operation of a vehicle with a faulty windshield wiper. The main elements of a windshield wiper are: a motor with a gearbox, links, arms, blades, and a glass washer, which consists of a tank, a pump, hoses, and nozzles. In modern cars, headlight washers are often integrated into the windshield washer system.
