The rhythmic swish-swish of your windscreen wipers can quickly turn into an ear-piercing screech if they become squeaky. Not only is this annoying, but it can also be a safety hazard, as it can make it difficult to see clearly while driving. Thankfully, fixing squeaky windscreen wipers is a relatively simple task that you can do yourself with a few basic tools. In this article, we’ll walk you through the steps on how to fix squeaky windscreen wipers so you can get back to driving with a clear view.
One of the most common causes of squeaky windscreen wipers is a lack of lubrication. Over time, the rubber on your wiper blades can become dry and brittle, which can cause them to squeak when they move across your windscreen. To fix this, simply apply a small amount of silicone-based lubricant to the rubber blades. You can use a cotton swab or a clean cloth to apply the lubricant, and make sure to wipe off any excess so that it doesn’t streak your windscreen. If the squeak persists after lubricating the blades, you may need to replace them. When replacing wiper blades, make sure to choose ones that are the right size for your car and that are made of a durable material such as rubber or silicone.
Another potential cause of squeaky windscreen wipers is a build-up of dirt and debris on the wiper blades or the windscreen itself. To clean the wiper blades, simply wipe them down with a damp cloth. To clean the windscreen, use a glass cleaner and a clean cloth. Make sure to remove all of the dirt and debris, as this can cause the wiper blades to squeak when they move across the windscreen. If the squeak persists after cleaning the wiper blades and the windscreen, you may need to adjust the tension on the wiper arms. To do this, locate the nuts or bolts that hold the wiper arms in place and loosen them slightly. Then, move the wiper arms up or down until the wiper blades make contact with the windscreen at the correct angle. Once you have adjusted the tension, tighten the nuts or bolts back into place.
Identify the Source of the Squeak
Identifying the origin of the squeaking noise is crucial for effective troubleshooting. Here’s a detailed guide to help you pinpoint the culprit:
1. Inspect the Wiper Blades
Wiper blades are the most common source of squeaking noises. Examine them closely for signs of wear or damage. Look for cracks, tears, or missing pieces that may be causing a rubbing motion against the windshield, resulting in the squeaking sound. Additionally, check for any dirt accumulation or debris that may be lodged within the blades or on their attachment points. These foreign particles can hinder the smooth movement of the blades, leading to the annoying noise.
Here’s a table summarizing the possible causes of wiper blade squeaks and their corresponding solutions:
| Cause | Solution |
|---|---|
| worn or damaged blades | replace blades |
| dirty or debris-covered blades | clean blades with a damp cloth and wipe away any debris |
2. Check the Wiper Arms
The wiper arms are the structures that hold the wiper blades in place and allow them to move across the windshield. Occasionally, the arms themselves can be the source of squeaking noises. Inspect the arms for any signs of misalignment or loose connections. Ensure that they are firmly attached to the vehicle and move smoothly when the wipers are activated. If there’s any play or looseness in the arm movement, it could be contributing to the squeaking sound.
3. Examine the Windshield
While less common, the windshield itself can sometimes be the cause of wiper squeaks. Check the surface of the glass for any chips, cracks, or other irregularities that might be causing friction with the wiper blades. A dirty or contaminated windshield can also lead to squeaking, as dirt particles can accumulate on the glass and interfere with the smooth movement of the blades.
Clean the Wipers and Windshield
Dirt and debris can build up on your windshield and wiper blades over time, causing squeaking noises. To clean the wipers and windshield:
- Mix a solution of equal parts white vinegar and water in a spray bottle.
- Spray the solution onto the windshield and wiper blades.
- Allow the solution to sit for a few minutes before wiping it away with a clean cloth.
Additional Tips for Cleaning the Windshield and Wipers
- Use a soft cloth to avoid scratching the windshield.
- Clean the wipers and windshield regularly, especially after driving in dusty or rainy conditions.
- Replace the wiper blades every six months to a year.
If cleaning the wipers and windshield doesn’t fix the squeaking noise, you may need to lubricate the wiper motor or linkage. To do this:
- Open the hood and locate the wiper motor.
- Apply a small amount of silicone spray or white lithium grease to the motor and linkage.
- Close the hood and test the wipers.
