Why do your windshield wipers make a scraping sound? This common issue can be caused by a variety of factors, including worn-out blades, debris on the windshield, or a lack of lubrication. Understanding the root cause can help you fix the problem and ensure your windshield wipers work efficiently.

What Causes Windshield Wipers to Make a Scraping Sound?

Are Your Wiper Blades Worn Out?

One of the most common reasons for a scraping sound is worn-out wiper blades. Over time, the rubber on the blades can deteriorate, leading to poor contact with the windshield. This can cause a scraping or squeaking noise, especially during use.

• Signs of Wear: Check for cracks, splits, or missing sections of rubber.
• Solution: Replace the blades if they appear damaged or have been in use for more than six months.

Is There Debris on Your Windshield?

Debris such as dirt, leaves, or small particles can accumulate on your windshield, causing your wipers to make a scraping sound as they pass over.

• Prevention: Regularly clean your windshield with a soft cloth and glass cleaner.
• Solution: Check your windshield for visible debris and clean it thoroughly.

Is There a Lack of Lubrication?

Windshield wipers need adequate lubrication to glide smoothly across the glass. A dry windshield or dry wiper blades can lead to a scraping noise.

• Solution: Use a windshield washer fluid that contains lubricants. This can help reduce friction and eliminate noise.

Are the Wiper Arms Misaligned?

If the wiper arms are not properly aligned, they may not make full contact with the windshield, leading to noise.

• Solution: Inspect the alignment of the wiper arms and adjust them if necessary. Consult your vehicle’s manual for guidance.

Is the Windshield Itself Damaged?

Sometimes, the issue may not be with the wiper blades but with the windshield. Scratches or chips on the glass can cause noise as the wipers move over them.

• Solution: Inspect your windshield for damage and consider having it repaired if necessary.
