What Causes the Clicking Sound When the Wiper Returns to Its Position?
2 Answers
Key areas to inspect include whether the wiper is properly positioned and if the wiper blade is aged. Below are detailed explanations of the related issues: Causes: It is highly likely due to wear or deformation of the wiper rubber, excessive resistance of the wiper, or slight deformation of the wiper arm from prolonged use, causing a rattling sound during operation. In such cases, simply prepare a wrench. If the wiper makes a rattling sound when moving upwards, use the wrench to gently twist the wiper arm inward toward the windshield. Wiper Rubber: Noise caused by issues with the wiper rubber itself. Since the wiper blade is made of rubber, prolonged use can lead to aging and hardening. Problems arising from extended use can only be resolved by replacing the blade. Proper wiping technique: The edge of the wiper blade should perform a dragging or sweeping motion on the windshield. Incorrect installation of a new blade can also cause noise.
I've also encountered the issue of the wiper making a clunking sound when returning to its position, and there are generally a few common causes. First, it could be that the joints in the wiper linkage mechanism have become loose, with worn linkages or bearings inside causing the noise. Second, there might be an issue with the motor's gear system, such as worn or loose gears, especially prone to clicking sounds during reversal. Another possibility is loose fastening screws, causing the entire wiper system to be unstable. Or, the wiper arm might not be properly aligned, leading to jerky movements when returning. To diagnose, you can gently shake the wiper arm to check for any wobbling or listen to pinpoint the source of the noise. If it's a minor issue, adding a bit of lubricant can help, but for serious problems, it's best to visit a repair shop for a thorough fix to avoid poor wiping performance that could affect driving safety. When I handled it myself, I started with simple troubleshooting to avoid unnecessary expenses. Regular maintenance, like spraying lubricant periodically, is crucial, especially before the rainy season.
