What Causes Windshield Wiper Noise?
2 Answers
The causes of abnormal noise in car windshield wipers include: 1. Looseness at the U-joint contact area of the wiper arm or aging/wear of the rubber blade; 2. Incorrect wiper arm angle, causing the wiper to exceed a 0-degree angle with the glass surface; 3. Sticky glass surface, often due to a difficult-to-remove mixed oil film formed from lack of cleaning. When using windshield wipers, regularly inspect the wiper blades. Pay attention to the following when checking wiper operation: 1. First moisten the windshield with water; otherwise, it may scratch the glass, and the high friction resistance could damage the blade or burn out the motor; 2. After turning off the wiper switch, the wiper blade should return to the lower side of the windshield and stop.
I remember when I first started driving, the squeaky wiper noise drove me crazy. I thought it was a major car issue, but it turned out to be quite a common problem. Most of the time, it's caused by aged or hardened wiper rubber blades that screech when in motion, or by uncleaned oil stains and dust on the windshield. It could also be due to improperly adjusted wiper arms during installation—either the spring is too tight or too loose. A simple fix is to wipe the glass before heading out in the rain or replace the rubber blades. Don’t underestimate this issue—blurry vision while driving is unsafe. I learned the hard way when the noise on the highway made me panic. Now, I know better: regular maintenance and replacing wipers every two years keeps things hassle-free.
