Why Do Windshield Wipers Make a Clicking Noise When Operating?
Is it Normal for My Windshield Wipers to Make a Weird Clicking Noise?
Yes, it can be normal for windshield wipers to make some noise. However, a clicking sound might indicate a problem. Here are a few common reasons for the noise:
Common Reasons for Clicking Noise
Worn Wiper Blades
If the blades are worn out or damaged, they may not make proper contact with the windshield, causing a clicking or skipping sound. Regular replacement of wiper blades is essential, as blades over a year old may not function optimally.
Improper Installation
If the wipers were recently replaced but not installed correctly, this can lead to misalignment and noise. Ensuring proper installation is critical for a smooth operation.
Debris
Dirt, leaves, or other debris trapped under the wiper blades can cause a clicking noise as they move across the windshield. Regular cleaning of the wiper blades is necessary to avoid this issue.
Faulty Wiper Motor or Linkage
If the motor or the linkage that connects the wiper arms is damaged or worn, it can produce unusual sounds. Regular inspection and maintenance of these components can help prevent such noises.
If the noise persists or if the wipers are not functioning properly, it may be a good idea to have them checked by a professional. In many cases, replacing worn-out parts or ensuring correct installation can resolve the issue.
Wiper Blade Chatter
Even with brand-new wiper blades, wiper blade chatter is common in many vehicles. Examining the wiper blades themselves first is crucial. Check if they are worn out, stiff, ripped, or dirty. Replacing wiper blades older than a year is advisable, as it will be money well spent.
Worn Out Wiper Mechanism
Wiper mechanism, including the motor or gearing, can also be the cause of the clicking. In some cases, it might be the relay in the fuse box. The relay might be malfunctioning, and what you're hearing could be the indicator of a defective motor.
Manual Installation Guide
From personal experience, switching from cheap blades to costlier wiper blades significantly improved the function. However, issues still arose because the blades were too long. Ensuring the correct blade size and length, as per the car's manual, is crucial. Sometimes, bent or damaged arms, guards, or bases can also cause the clicking noise. If the guard that parks the wipers when off is bent or damaged, it should be repaired or replaced.
Conclusion: Regular inspection, proper installation, and timely replacement of worn-out parts are essential to prevent unrelated clicking noises from windshield wipers. Consulting a professional for any persistent issues can ensure a safe and efficient driving experience.
