What are the reasons for wiper blade noise?
2 Answers
Loud noise when the wiper is activated is mainly caused by: 1. The spring of the wiper arm being too tight. 2. Excessive wear on the friction surface of the wiper blade. 3. The friction surface of the wiper blade being uneven or deformed. 4. Solutions: (1) If the spring of the wiper arm is too tight, the solution is to slightly stretch the spring. (2) If the wiper blade is worn or the friction surface is uneven or deformed, it is recommended to replace the wiper blade. (3) You can check if the frame holding the rubber strip of the wiper is slightly bent.
Oh I've encountered this issue several times! The wiper blades screeching against the windshield is absolutely maddening. The main reason is the aging and hardening of the wiper rubber – over time, the rubber loses its elasticity and creates that irritating friction noise against the glass. Oil film or accumulated dust on the windshield can also worsen the noise; I once discovered a layer of bug residue or tree sap on my windshield that caused the wipers to squeal sharply. Dry weather conditions make the screeching particularly noticeable – I recommend spraying some windshield washer fluid to moisten the surface first. Additionally, if the wiper arm is misaligned or the pressure is too high/low, problems can arise. The DIY solution is simple: first clean both the glass and wiper rubber with a damp cloth; if the noise persists, check if the wiper is deformed – replacing the rubber insert only costs a few dozen yuan. Delaying repairs may lead to windshield scratches which are even more annoying, so timely maintenance can save you a lot of hassle.
