What Causes the Wiper to Make Abnormal Noises?
4 Answers
The reasons for abnormal noises from the wiper are: 1. There are foreign objects on the windshield; 2. Damage to the wiper linkage mechanism; 3. Wiper angle issue; 4. Friction in the wiper linkage bushing. Solutions for abnormal noises from the wiper: 1. Use windshield washer fluid to clean the front windshield; 2. Regularly clean or replace the wiper blades; 3. Replace the linkage mechanism parts; 4. Adjust the wiper angle. The function of the wiper is to brush off raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Types of wipers include traditional intermittent wipers and rain-sensing wipers.
My windshield wipers were making a clicking noise last week, which really annoyed me. Upon inspection, I found that the main issue was the aging and hardening of the wiper blades. The rubber strips had lost their elasticity due to sun exposure and rain, causing friction against the glass and producing the noise. Oil film or dirt on the glass surface can also exacerbate the noise, especially in urban areas with more dust or bird droppings. I bought a specialized cleaner to wash the glass and replaced the wiper blades, which immediately made them much quieter. Additionally, incorrect installation, such as bent wiper arms or loose screws, can also cause this problem. If necessary, use a tool to tighten them. It’s recommended that car owners check the condition of their wiper blades every six months to avoid sudden failures. Choosing silicone-based products can offer better durability and reduce noise.
After driving multiple cars, wiper noise usually stems from wiper blade wear or environmental factors. Aged rubber strips become brittle, causing squeaking when wiping due to bouncing; in winter, wipers frozen to the windshield being forcibly activated can lead to loud creaking at the joints; loose connections at the motor may also transmit noise. I once experienced noise caused by a misaligned wiper arm, which was resolved after adjusting its angle. Avoid activating wipers on dry glass as it accelerates wear and increases noise. Regularly wiping the rubber strips with soapy water helps maintain their softness. Remember to check wiper condition before rainy days to ensure safe driving with clear visibility.
There are various reasons for wiper noise. Hardened rubber due to aging causes heavy friction sounds when wiping; excessive oil stains on the windshield increase resistance; rusted transmission components lead to jerky noises. Cleaning windshield stains is effective—I often use diluted dish soap to remove oil films. Check if the wiper blade installation position deviation is too large to avoid oblique operation.
