How to Deal with Noises from Car Windshield Wipers?
1 Answers
If the noise from the wiper blade is caused by the wiper blade itself, the simplest and most effective solution is to directly replace it with a new one. Generally, it is recommended to replace the wiper blade every one to two years. If the noise is due to foreign objects stuck between the wiper blade and the windshield, check and clean the wiper blade or any debris underneath it to ensure the area is clean. Solutions for other causes of noise are as follows: 1. Noise from the wiper linkage bushing: Over time, the wiper linkage mechanism may age, the wiper arm spring may lose elasticity, and the bushing may wear out or even fall off. Please inspect the wiper arm or linkage bushing. 2. Noise from the wiper motor: If the wiper motor itself is making noise, it may be a sign that the motor is nearing the end of its lifespan. It is recommended to have it checked in detail at a professional repair shop. 3. A squeaking noise when the wiper moves across the windshield is often due to incorrect wiper arm angle, causing the blade to jump on the windshield. If the wiper blade is normal, adjust the wiper arm angle so that the blade is perpendicular to the windshield. You can use pliers to adjust it—place a cloth under the wiper arm head, grip it with pliers, and bend it slightly to ensure the blade is perpendicular to the windshield. 4. Deformation of the linkage mechanism or issues with the motor or interval relay (e.g., operating too fast, too slow, or continuously) may also cause noise. Additionally, prolonged use may lead to deformation, jamming, rust, or abnormal movement of the mechanism. If you have just replaced the wiper blade, check if there is dirt or oil residue on the windshield. Clean the windshield with a cleaning solution or try another new set. If the noise persists, adjust the wiper arm angle with pliers. However, it is best to have it adjusted with professional tools at a repair shop.
