How to Solve Windshield Wiper Chattering?
2 Answers
Solutions for windshield wiper chattering: 1. If the chattering is caused by the wiper blade, which is a rubber product that hardens and ages over time, leading to chattering and ineffective cleaning, the simplest and most effective solution is to replace the wiper blade with a new one; 2. If the chattering is due to a misaligned wiper arm, remove the wiper blade and use two wrenches to adjust—one to hold the wiper arm steady and the other to adjust its angle until it fits snugly against the windshield; 3. If the chattering is caused by motor issues, such as insufficient power from the wiper motor, which results in shaking during operation, this may indicate motor damage or wear. In such cases, it is recommended to visit a professional repair shop for inspection and repair.
Once while driving in a heavy rainstorm, my windshield wipers suddenly started skipping badly, almost making it impossible to see the road. The issue turned out to be aged wiper blades with deformed rubber strips that couldn't evenly adhere to the glass. A quick fix is to first clean the windshield by wiping off dust and grease with warm water and dish soap; then inspect the wiper blades for cracks or looseness and replace them promptly if needed. Wiper blades for many car models are quite affordable, and you can easily replace them yourself. I've also encountered skipping caused by tiny scratches on the glass surface, which can be improved using a dedicated glass polishing compound. For regular maintenance, avoid using wipers on dry glass as it accelerates wear. Addressing skipping issues promptly makes driving in the rain much safer, eliminating worries about blurred vision.
