What Causes Windshield Noise?
1 Answers
Damaged wiper blades. Below is a detailed explanation of the reasons for windshield noise: 1. The rubber strip of the wiper blade has aged, becoming hard and deformed, preventing it from fully adhering to the car glass, resulting in noise. 2. The wiper blade has cracks, fissures, aging, rust, or deformation issues. 3. Noise caused by a dirty windshield. If the vehicle is parked outdoors for an extended period without timely washing, a layer of oil film can easily form on the windshield. The replacement cycle for wiper blades is generally about 1 year. The formation of oil films includes insect oil, tree sap, and exhaust emissions, which accumulate on the front windshield over time to form a transparent substance.
