What Causes Windshield Wiper Noise When Wiping Glass?
1 Answers
Car windshield wipers make noise when wiping glass due to the following reasons: 1. Impurities on the glass or quality issues with the wiper blades. Over time, the rubber strips (wiper blades) may age, deform, or harden, preventing proper contact with the glass. 2. Deformation of the linkage mechanism or issues with the motor and intermittent relay (such as operating too fast, too slow, or continuously). With prolonged use, structural deformation, jamming, or rust can cause abnormal operation. 3. Poor motor performance. Windshield wipers are tools installed on the front glass of motor vehicles to prevent rainwater and other debris from obstructing vision by performing simple cleaning.
