Why Does the Wiper Make a Squeaking Sound When Wiping the Windshield?
2 Answers
Reasons and solutions for wiper squeaking when wiping the windshield are as follows: 1. Wiper blade aging: Wiper blades are rubber products that can harden and age over time, especially in winter. Solution: Replace the wiper blades. Generally, it is recommended to replace wiper blades every one to two years. 2. Foreign objects between the wiper blades: When the wiper is turned on, a sharp friction sound may occur between the wiper blade and the windshield. Solution: Clean any foreign objects from the wiper blades or the area beneath them to ensure cleanliness. 3. Incorrect wiper arm installation angle: If the wiper blade jumps on the windshield, it can cause noise. Solution: Adjust the angle of the wiper arm. 4. Deformation of the linkage mechanism: Deformation of the mechanism or issues with the motor, interval relay, or the mechanism itself, such as deformation, sticking, or rust. Solution: It is recommended to clean the windshield with a cleaning solution or replace the wiper blades.
Oh, I know all about that wiper squeaking! Just dealt with it last week. There are three main causes: First, the rubber blade hardens with age—check if it feels rough to the touch. Second, heavy oil film buildup on the windshield, especially noticeable after highway driving when the front is covered in bug splatter. Here’s a pro tip: mix dish soap with warm water and scrub the windshield thoroughly, then use a clay bar to remove the oil film before testing. Third, uneven pressure due to a warped wiper frame—lift the wiper and run it without touching the glass to hear the noise. Bonus tip: Never use tap water as washer fluid! Mineral deposits will accelerate rubber hardening. If the noise persists after replacing the blade, the wiper arm’s downward pressure needs adjustment—best left to a mechanic.
