What Causes the Noise When Wiper Blades Rub Against the Windshield?

[SanMalachi]

The reasons for the noise when wiper blades rub against the windshield are: 1. The wiper blades have aged and hardened; 2. There is foreign matter between the wiper blades and the windshield; 3. The linkage mechanism is deformed or there is an issue with the motor; 4. Problems with the intermittent relay; 5. The wiper arms may also produce noise if they move too fast, too slow, continuously, or if their angle is incorrect. Steps to replace wiper blades: 1. Lift the wiper arm; 2. Press the clip underneath to remove the wiper blade; 3. Take off the wiper blade; 4. Pry up the front end of the middle clip; 5. Insert the new wiper blade into the middle clip, pull it tight by hand, and once you hear a click, the replacement is complete.
