If your rear windshield wiper makes noise, it could indicate a problem that needs attention. Addressing this issue promptly can prevent further damage and ensure your wiper functions correctly, providing you with clear visibility during adverse weather conditions.

Why Does My Rear Windshield Wiper Make Noise?

Common Causes of Noisy Rear Windshield Wipers

1. Worn-out Wiper Blades: Over time, wiper blades can become brittle or cracked, leading to uneven contact with the windshield and causing noise.

2. Dirty or Contaminated Windshield: Dirt, debris, or grime on the windshield can create friction, resulting in squeaking or chattering sounds.

3. Improper Installation: If the wiper blade is not installed correctly, it might not sit flush against the windshield, causing noise.

4. Damaged Wiper Arm: A bent or damaged wiper arm can prevent the blade from making proper contact with the windshield, leading to noise.

5. Insufficient Lubrication: The wiper arm’s pivot point may lack lubrication, causing squeaking as it moves.

How to Fix a Noisy Rear Windshield Wiper

1. Inspect and Replace Wiper Blades: Check for signs of wear and replace the blades if necessary. Opt for high-quality blades for better performance and durability.

2. Clean the Windshield and Blades: Use a glass cleaner to remove dirt and grime from the windshield. Wipe the blades with a damp cloth to ensure they are free from debris.

3. Check Installation: Ensure that the wiper blades are installed correctly. Refer to your vehicle’s manual for installation instructions.

4. Examine the Wiper Arm: Look for signs of damage or bending. If the arm is bent, carefully realign it or replace it if necessary.

5. Lubricate the Pivot Point: Apply a small amount of lubricant to the pivot point of the wiper arm to reduce friction and noise.

Look for visible signs of wear such as cracks, splits, or fraying on the rubber blades. If the wipers leave streaks or do not clear the windshield effectively, it’s time for a replacement.

Can I Use WD-40 on My Wiper Blades?

It’s best to avoid using WD-40 on wiper blades, as it can degrade the rubber. Instead, use a silicone-based lubricant for the pivot points and keep the blades clean with soap and water.
