What to Do When the Rear Wiper Makes Noise?
4 Answers
The causes and solutions for rear wiper noise are: 1. Wiper blade issues: Over time, wiper blades can age and harden, leading to noise. The solution is to replace the wiper blades with new ones; 2. Incorrect wiper arm angle: If the wiper blade jumps on the windshield, causing noise, adjust the wiper arm angle so that the blade is perpendicular to the windshield plane; 3. Foreign objects between the wiper blade and windshield: When the wiper is turned on, friction between the blade and windshield can produce a sharp noise. Owners should check and clean any debris under the wiper blade to ensure the wiper area remains clean.
I've been driving for many years and recently encountered the annoying issue of squeaky rear wipers. It happened during heavy rain, and the sound was as sharp as nails on a chalkboard. I first pulled over and cleaned the rear window and wiper blades with a wet cloth, as oil and dust buildup can cause friction noise. However, the noise persisted, so I inspected the blades and found the rubber had aged, with cracks along the edges. I bought a new set of wiper blades and replaced them myself—it was straightforward, and there are tutorials online. After the replacement, the noise disappeared immediately, making my driving experience much more pleasant. I recommend everyone pay attention to regular maintenance, cleaning the glass before rain and ensuring no debris accumulates under the blades. If the problem persists, it might be due to a deformed wiper arm or a loose motor, requiring a visit to the repair shop. Regular wiper maintenance can save you a lot of money—check them every six months and opt for professional-brand replacements for better durability.
As a car enthusiast, when encountering rear wiper noise, I first check a few simple causes. Common issues include worn or aged wiper blades, where hardened rubber causes loud friction; dirt or wax residue on the glass can also trigger noise; or a deformed arm causing poor blade contact. I recommend first trying some windshield washer fluid—if it helps, dust may be the culprit. Then thoroughly clean the rear window with warm water and dish soap to remove grease. Inspect the blades for cracks and replace them if needed—it’s a cost-effective DIY fix. If the noise persists, gently adjust the arm’s tension angle to ensure it presses firmly against the glass. Avoid excessive force to prevent part damage. If these steps don’t work, the motor mount might be loose, requiring professional tools for tightening. Make blade maintenance a habit—clean them with a soft cloth and avoid chemicals to extend their lifespan. These practical DIY tips help detect sound changes early, preventing minor issues from escalating.
The rear wiper noise is really annoying, and the sound distracts you while driving, especially in rainy weather when visibility is poor, making it unsafe. The possible causes are mostly aging wiper blades, dirty glass, or issues with the arm bracket. You should deal with it as soon as possible and not delay: first, check if the rubber on the wiper blade is cracked, and replace it if there's a problem; then clean the glass to remove oily stains; if it still makes noise after adjusting the arm bracket, it means the parts are severely worn and need to be replaced. Fixing these small issues promptly can ensure driving safety—don't wait until it rains to rush to the repair shop.
