Why is the windshield wiper so loud？
1. Aging of wiper blade: two wiper blades are rubber products. After a period of time, aging and hardening will occur, and it is more significant in winter. Most wiper blades advocate replacement every one to two years.
2. There is a foreign body in the middle of the wiper blade: when the wiper is opened, there will be a sharp sound of friction between the wiper blade and the front windshield glass. The car owner can detect and remove a foreign body under the wiper blade or two wipers to ensure that the location of the two wipers is clean.
3. The installation Angle of the two scraper arms is wrong: it will affect the beating of the rain scraper on the windshield, so it will cause a sound. If the two wipers are normal, the Angle of the wiper arm needs to be adjusted, and the two wipers should be perpendicular to the windshield plane.
