How to Fix 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 use a wrench to slightly adjust the curvature of the wiper arm until it fits snugly against the windshield; 3. Have it inspected and repaired at a professional auto repair shop. The wiper, also known as a windscreen wiper or windshield wiper, is a blade structure installed in front of the windshield. It consists of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. The function of the wiper is to remove rain, snow, and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety.
Last time when I was driving in the rain, my windshield wipers suddenly started jumping, leaving streaks and obstructing my view. I first pulled over to check the windshield and found a layer of oil residue, probably caused by road dust and vehicle exhaust. I sprayed glass cleaner and wiped it repeatedly several times, which basically restored normal operation. But then when I tested the wiper blades, they felt stiff and had some cracks, indicating they were too old and overdue for replacement. So I went to an auto parts store and bought a new set of blades, installing them myself—they were affordable and worked great. If the wipers still jump after cleaning the glass, it might be due to misaligned wiper arms or them being knocked out of position, requiring a simple angle adjustment. I think regular maintenance before the rainy season can prevent such troubles. Doing it myself saves a lot of money and is much safer. Now that it's become a habit, I rarely have issues anymore.
