Why Does the Wiper Make a Squeaking Noise?
2 Answers
The reasons for the wiper making a squeaking noise are: 1. Long-term use causing the wiper blade to age and harden; 2. Foreign objects stuck between the wiper blade and the windshield; 3. Friction in the wiper linkage bushing; 4. Malfunction of the wiper motor. The wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its function is to remove rain, snow, and dust that obstruct the view on the windshield. Precautions for using the wiper include: 1. Replace or clean the wiper blade promptly when severe wear or dirt is found; 2. When checking the wiper's operation, wet the windshield with water first; 3. After turning off the wiper switch, the wiper blade should return to the lower side of the windshield and stop.
As a veteran driver with over 20 years of experience, I've long grown accustomed to windshield wiper noises. Usually, the main culprit is aged rubber wiper blades that harden and crack from UV exposure, causing squeaky friction against the glass. Oil film or dust on the windshield surface also increases resistance, especially right after rain. Loose or rusted spring connections can produce strange sounds too. My routine solution is thoroughly cleaning the windshield with dish soap first, then lightly sanding the edges of the wiper blades - an economical and effective trick. If that fails, I simply replace the blades with new ones bought from e-commerce platforms for just tens of yuan, a DIY job taking mere minutes. Remember to regularly check the wiper arm's tension and tighten if loose. These small techniques have saved me considerable repair costs over the years.
