What Are the Causes of Windshield Wiper Squeaking?

[CharlieFitz]

The causes of windshield wiper squeaking can be summarized into the following 5 points: 1. If the wiper squeaks when moving upward, it indicates the wiper frame is twisted upward. If the squeaking occurs when moving downward, the frame should be twisted in the opposite direction until the noise disappears; 2. Issues with the wiper blade itself: Over time, the blade may age and harden. The simplest solution is to replace it with a new one; 3. Foreign objects between the wiper blade and the windshield: Friction between the blade and the windshield can produce a sharp sound. Check and clean any debris under the wiper or the blade to ensure cleanliness; 4. Deformation of the linkage mechanism: Abnormal noises may also be caused by the motor, interval relay, or prolonged use leading to deformation, jamming, or rusting of the mechanism itself; 5. Incorrect angle between the wiper and the wiper arm: This can cause the wiper blade to jump on the windshield, resulting in squeaking.
