How to Fix Wiper Blade Chattering?
1 Answers
Here are the causes and solutions for wiper blade chattering: 1. Wiper blade issues causing chattering: Wiper blades are rubber components that harden and age over time, especially in winter. If they no longer clean effectively, the simplest solution is to replace them. Generally, wiper blades should be replaced every 1-2 years. 2. Debris between the wiper blade and windshield causing chattering: When the wiper is activated, a sharp friction noise may occur between the blade and windshield. Check and clean any debris lodged under or around the wiper blade to ensure cleanliness. 3. Wiper linkage bushing wear causing chattering: In older vehicles, the wiper linkage mechanism may age, reducing the spring tension of the wiper arm and wearing out the bushings, potentially leading to detachment. Inspect the wiper arm and linkage bushings. 4. Wiper motor issues causing chattering: If the wiper motor lacks sufficient power and chatters, it may indicate the end of its lifespan. A detailed inspection at a professional repair shop is recommended.
