Windshield wipers chatter when they skip or make noise across the windshield, often due to issues with the wiper blades, arm alignment, or windshield condition. This problem can reduce visibility and become a safety hazard if not addressed. Understanding the causes can help you troubleshoot and fix the issue effectively.
Why Do Windshield Wipers Chatter?
Windshield wipers chatter due to several reasons, including worn-out blades, improper installation, or a dirty windshield. Addressing these issues can improve the performance and lifespan of your wipers.
What Are the Common Causes of Wiper Chatter?
-
Worn-Out Wiper Blades: Over time, wiper blades can become hard or cracked, leading to uneven contact with the windshield. This causes skipping and noise.
-
Improper Installation: If wiper blades are not installed correctly, they may not align properly with the windshield, causing chatter.
-
Dirty or Contaminated Windshield: Dirt, grime, or residue on the windshield can prevent smooth movement of the wipers, resulting in chattering.
-
Damaged Wiper Arms: Bent or misaligned wiper arms can affect the pressure distribution on the blades, leading to chatter.
-
Temperature Extremes: Extremely hot or cold weather can cause the rubber on the blades to harden or warp, affecting performance.
How Can You Fix Windshield Wiper Chatter?
To fix wiper chatter, you’ll need to diagnose the specific cause and take appropriate action. Here are some steps you can follow:
-
Inspect and Replace Blades: Check the condition of your wiper blades. If they appear worn or damaged, replace them with new ones.
-
Clean the Windshield: Use a glass cleaner and a microfiber cloth to thoroughly clean the windshield, removing any dirt or residue.
-
Check Wiper Arm Alignment: Ensure the wiper arms are aligned correctly and not bent. Adjust or replace them if necessary.
