Windshield wipers are essential components for ensuring driving safety, ensuring optimal visibility in bad weather. However, with prolonged use, they may start to emit annoying noises, such as squeaking or screeching, which not only compromise driving comfort, but may also indicate a malfunction. In this article, we look at the most common causes of noisy windshield wipers and how to solve the problem.
Noisy windshield wipers: the causes
The noise emitted by windshield wipers can have various causes, often linked to wear or installation problems. Let's analyze the main reasons:
1. Worn brushes
Windshield wiper blades are subject to constant wear. Over time, the rubber material deteriorates, losing its flexibility and ability to adhere to the windshield. This causes increased friction during movement, generating annoying noises such as squeaking or screeching.
2. Damaged wiper arms
If the wiper arm is damaged or rusted, it can cause noise. Rust buildup or obstructions, such as leaves or debris, can impede smooth movement, creating friction and unwanted noise.
3. Dry friction
A common mistake is to turn on the windshield wipers without using washer fluid. This causes dry friction between the blades and the windshield, generating an unpleasant sound. In addition, this type of use can accelerate the wear of the blades.
4. Faulty installation or incompatible brushes
Another cause may be related to incorrect installation or the use of brushes that are not compatible with the car model. If the brushes have been replaced recently and the noise appeared immediately after, it is likely a problem with assembly or the choice of the wrong model.
5. Dirty or contaminated windshield
Sticky substances on the windshield, such as resin or accumulated dirt, can cause the wiper blades to not work properly and not slide smoothly. This can create vibrations and noises during operation.
Noisy Windshield Wipers: What to Do
Once you have identified the cause, there are a number of solutions you can adopt to solve the problem of noisy windshield wipers. Here is what to do depending on the situation:
1. Replace worn brushes
If the wipers are worn, the most immediate solution is to replace them. It is important to do so promptly to prevent them from scratching the windshield, damaging it irreparably. It is advisable to choose high-quality wipers that are compatible with the model of your car.
2. Treat the wiper arms
If the arms are rusty, you can apply a lubricating oil to restore proper operation. If the damage is excessive, it is best to replace the entire mechanism. It is also important to remove any obstacles that may prevent the arm from moving smoothly.
3. Make sure the windshield washer fluid reservoir is full
Avoid using dry brushes. Check the windshield washer fluid level regularly and, in an emergency, use demineralized water until you can purchase a specific cleaner.
4. Clean the windshield
If resin or other contaminants have accumulated on the glass, a thorough cleaning with specific detergents is necessary. Once these impurities are removed, the wipers should operate quietly again.
5. Check that the brushes are installed correctly
If the blades are installed incorrectly or are not compatible with the vehicle, it is advisable to redo the installation or replace them with an appropriate model. Blades from reputable brands offer longer life and better performance.
Conclusion
Noisy wipers can be a sign of a variety of problems, from simple blade wear to installation defects or accumulated dirt on the windshield. Taking timely action is essential to avoid damage to the windshield or wiper motor. Keeping your windshield wiper system in good condition ensures optimum visibility and safe driving in all weather conditions.
Replacing your wiper blades regularly, checking the arms for rust, and keeping your windshield clean are the main steps you can take to avoid annoying noises and future problems.
