Basic Checks and Maintenance to Eliminate Wiper Blade Noise

 

Nothing is more annoying than the squeaking, chattering, or scraping noise of your car’s wiper blades when they’re in use. Not only does it disrupt the peace during your drive, but it can also be a sign that your wipers aren’t working as effectively as they should. Novoflow suggests these noise issues can be resolved with some simple basic inspections and maintenance.

 

1. Inspect the wiper blades themselves.

Over time, wiper blades can become worn, cracked, or hardened due to exposure to sunlight, rain, and extreme temperatures. If you notice any of these signs, it’s a clear indication that the blades need attention. Even small cracks or a loss of flexibility can cause them to skip across the windshield, resulting in noise.

Gently run your finger along the edge of the blade – if it feels rough or uneven, that’s likely the culprit.​

 

2. Clean the windshield and the wiper blades.

Dirt, grime, road salt, and even tree sap can build up on both the windshield and the blades, leading to friction and noise. Insufficient or no washer fluid means the wipers are trying to clean a dry or nearly dry windshield, leading to increased friction and noise.

Start by thoroughly cleaning the windshield with a good quality glass cleaner. Make sure to remove all traces of debris, especially in the areas where the wipers make contact. Then, take a soft cloth dampened with warm, soapy water and wipe down the wiper blades. This will remove any accumulated dirt that might be causing them to stick or scrape.​Last, Ensure your washer fluid reservoir is full.

 

3. Check the wiper arm tension

Another important step is to check the wiper arm tension. If the wiper arms are too loose, the blades won’t press firmly enough against the windshield, causing them to chatter. Conversely, if they’re too tight, the excessive pressure can lead to scraping and noise. Most wiper arms have a spring mechanism that maintains the tension.

You can test the tension by gently lifting the wiper arm away from the windshield – it should offer a consistent amount of resistance. If it feels too loose or too tight, you may need to adjust it. Gently lift the wiper arm and visually inspect the blade’s angle to the windshield. It should be at roughly a 90-degree angle to the glass, allowing it to flip smoothly.Consult your car’s owner’s manual for guidance on how to do this properly, as the method can vary between different makes and models.​

 

4. Consider the condition of the wiper motor and linkage

While less common, a faulty motor or worn linkage can also cause noise. If you hear a grinding or clicking sound coming from the wiper motor area when the wipers are running, it might indicate a problem with these components. However, this is a more complex issue and may require the expertise of a professional mechanic to diagnose and repair.​

 

5. Replace Wiper Blades:

This is the most common reason for noisy wipers. Over time, the rubber on the blades hardens, cracks, tears, or becomes brittle due to exposure to UV light, extreme temperatures, and general wear and tear. Worn blades lose their ability to glide smoothly and effectively.

If your blades are old (typically recommended to replace every 6-12 months, or sooner if you live in harsh climates), damaged, or if the above steps haven’t solved the noise, it’s time for new ones.

When purchasing, consider beam or hybrid blades, as they often offer quieter operation and better performance than traditional conventional blades.Ensure you get the correct size and attachment type for your vehicle.

By performing these basic checks and maintenance tasks regularly, you can often eliminate wiper noise and ensure that your wipers function smoothly and quietly. Not only will this make your drives more pleasant, but it will also help keep your windshield clear for safe driving.​
