Why does the newly replaced wiper make noise during operation?
2 Answers
The reasons why the newly replaced wiper makes noise during operation are: 1. If the wiper makes a "squeaking" noise when moving upward, it indicates that the wiper frame is twisted upward. If the wiper makes noise during both upward and downward movements, the wiper blade needs to be replaced; 2. The wiper blade itself may be the issue. Wiper blades are rubber products and will harden and age over time; 3. There may be foreign objects between the wiper blade and the windshield. The owner can check and clean any foreign objects under the wiper blade or the wiper to ensure the wiper area is clean; 4. Deformation of the linkage mechanism or faults in the motor or interval relay may also cause noise; 5. Incorrect angle of the wiper arm may cause the wiper blade to jump on the windshield, resulting in noise.
It's quite common for new wiper blades to make noise. I've replaced them several times, mainly due to improper installation. If the wiper blade isn't fully seated in the mounting slot or the rubber strip is at the wrong angle, it can cause squeaking when rubbing. First, clean the windshield thoroughly—residues like oil film often cause issues. Spray glass cleaner and wipe it down with a damp cloth. Check if the wiper arm pressure is even; too loose and it bounces, too tight and it wears out quickly—adjust the spring clip. New rubber strips can be stiff at first; driving for a while helps soften them. When replacing, ensure the size matches—oversized blades may hit the frame and make noise. Avoid cheap, low-quality blades as poor materials crack easily. Address the noise promptly—it’s not just annoying but may also scratch the glass and impair visibility. Regular maintenance prevents issues, ensuring safe driving in the rain.
