How to Solve Wiper Blade Chattering?
2 Answers
The solutions for wiper blade chattering are: 1. Replace with new wiper blades; 2. Lift the wiper arm, remove the blade, and adjust the angle between the arm and windshield until it fits snugly against the glass; 3. Have the motor inspected at a repair shop. The causes of wiper blade chattering are: 1. Aging or hardening of the wiper blade; 2. Bent wiper arm; 3. Insufficient motor power. The wiper, also known as a windscreen wiper or windshield wiper, is a blade structure installed in front of the windshield. Its function is to remove rain, snow, and dust adhering to the vehicle's windshield, improving driver visibility and enhancing driving safety.
I've been repairing cars for over 20 years and have seen too many cases of wiper blade chatter. The most common cause is aged or deformed rubber blades - when they harden and lose flexibility, they bounce up and down during wiping. Another frequent issue is oil film or tree sap buildup on the windshield creating uneven friction, causing the blade to stick and then snap back. Loose wiper arm springs are also problematic as they can't maintain proper pressure. My standard repair approach involves three steps: First, thoroughly clean the windshield with glass degreaser. Then remove the wiper blade to inspect the rubber - if hardened, replace the insert. Finally, manually adjust the wiper arm tension. If chatter persists, the entire wiper linkage likely needs replacement.
