5 Causes of Squeaky or Skipping Wiper Blades
Windshield wipers are an inexpensive and simple component that is often overlooked in basic maintenance.
- If it starts to rain after a long period of sunshine, you need to make sure your wipers are working properly so you can see through your windshield.
- If your wipers start squeaking or jumping one day, you need to get the problem fixed as soon as possible.
- If you experience a strong squeaking noise, it could be an indication that there is something sharp underneath the wiper blades, which could also scratch your windshield if not addressed.
Common Causes of Squeaking Windshield Wipers
There are a few reasons why wiper blades may squeak or jump. Luckily, they’re all relatively cheap and easy to fix.
Most people should be able to fix the problem themselves with this easy DIY project. New wiper blades usually come with wiper installation instructions.
1) Your windshield is dirty or dry
When your windshield is dirty, small pieces of dirt and debris are picked up by the wipers and scraped all over the windshield as they move. Before replacing your wipers, make sure your windshield washer fluid is filled and working effectively.
If you notice that there isn’t much washer fluid on your windshield, check your washer fluid nozzles. These are usually located behind the hood, near the windshield. Over time, the washer fluid nozzles can become clogged with dirt.
You should see a consistent spray pattern from the washer fluid nozzles.
2) Dirt on the wipers
In this case, spraying windshield washer fluid is unlikely to remove the deposits. Pull up the wiper blades and check the rubber. The surface should be clean and smooth. Any imperfections can cause squeaking when the wipers move.
3) Product deposits
Some products, such as car wax, can squeak or skip when applied to your windshield.
If you have just washed your car and notice your wipers squealing or malfunctioning, you should remove the product from your windshield and switch to a good car glass cleaner, such as Invisible Glass or RAIN-X.
4) Old wiper blades
As wiper blades get older, the rubber becomes harder. The leaves that once acted as pullers become brittle and may even break off.
5) The wrong length of wiper blades
When you’re shopping for windshield wiper blades, you’ll likely find a book with wiper blade sizes for every make and model. Wiper blade sizes vary depending on which side (driver side, passenger side, rear window) you’re looking for, even for the same car.
If you buy a wiper blade that’s too long or too short, the wiper may have the wrong curvature or may rub against things other than the glass of your car as you wipe. Double-check your owner’s manual, look for a book at an auto parts store, or search online to find the right wiper blade size for your specific vehicle.
