What Causes the Ticking Sound in the First Gear of the Wiper?

[VonEvangeline]

It could be due to the aging of the wiper. Replacing it with a new one should solve the issue. Wipers require frequent replacement, typically every six months. Over time, they may fail to clean effectively or start producing unusual noises. Below are the reasons why wipers make noise when wiping the windshield: 1. Wiper Arm and Wiper Blade: Common causes include impurities on the glass, poor-quality wiper blades, or aging, deformation, or hardening of the rubber strip (wiper blade) due to prolonged use. 2. Linkage Mechanism: Deformation of this mechanism or issues with the motor, intermittent relay, etc., can lead to unusual noises. Additionally, structural deformation over time can cause abnormal operation, which may also result in "unusual noises." 3. Motor Section: Poor motor performance or external circuit voltage issues can cause abnormal rotation or noise, such as insufficient operating voltage. Other potential causes include relay control issues, which may also lead to abnormal operation or noise. Adjustment Method: Primarily involves adjusting the angle of the wiper linkage arm.
