Automobiles are manufactured with a windshield to protect drivers and passengers, especially when driving at high speed. The windshield is designed to protect the driver and passengers by receiving all the dirt and contaminants that fly around.
Meanwhile, the windshield wipers help to clear off dirt, water, etc., from the vehicle’s windshield. However, squeaky windshield wipers can become a challenge you will have to deal with overtime.
This article unveils the common causes of squeaking sound in a vehicle’s windshield wipers and how to solve the problem.
What Causes Squeaky In My Car Windshield Wipers?
Consider some reasons why your windshield wipers might make distracting noises and how to stop the squeak:
#1. Wiper or Windshield Contamination.
Dust or other road debris may have dirtied either your wipers or your windshield. You may not be able to see contaminants that well against the dark wiper blades.
You should be able to check this problem by cleaning your wiper blade and window glass with a commercial cleaner or a rag that has been dipped in vinegar. Afterwards, you can just run your windshield washer to rinse the blades and window.
Even though you should find cleaning your wiper blades a simple and quick chore, it’s important to attend to this task promptly. Dust, sand, and small pebbles can scratch the window as they rub against it.
It’s usually best to avoid using petroleum-based solutions, like WD-40, on wiper blades. If you use products like this frequently, they can dissolve the rubber and shorten the life of your blades.
#2. Poor Wiper Installation.
These days, it’s common to buy new wiper blades at an auto parts store. Very often, the employees at this kind of store will offer to install simple parts as a convenience to customers.
This allows you to stop, make a quick purchase, and be on your way without getting your hands dirty.
However, it’s not likely that these employees are trained technicians. Some wiper assembles and some wipers are more complex than others.
If cleaning your blades doesn’t fix your problem, you might bring your car to us to have the wiper and blade installation checked by a professional.
#3. Old Rubber.
Many people don’t realize that they should replace their wiper blades at least once a year, and sometimes, they may require changing after only six months.
Depending upon conditions, the materials used to make the flexible part of the wiper often get hard and brittle over time.
This can cause squeaking, and it also may cause your wiper break to break just when you need to use it during a rainstorm. In other cases, the hard rubber might even damage your window glass.
Wiper blades don’t cost a lot, and your driving safety depends upon them. You may not notice that your wipers don’t work very well until you get caught in a downpour, so you’re better off changing your blades on schedule.
#4. Manufacturer’s Defect.
Some folks have complained after they bought new wipers from an online source or a local auto parts store.
They were very disappointed because their the wipers squeaked from the first day. Even if the wipers were installed correctly, it’s possible that they have a defect from production and need to be replaced immediately.
In some cases, the wipers may have been improperly stored in the box for a long time, so the rubber has already hardened or cracked even though they were never used on the road.
You should also be entitled to return the blades for a refund. You may be doing the original seller a favor by letting them know that their wipers were defective or aged. Next time, you may want to purchase your wiper blades from a more trusted source.
How To Fix Squeaky Windshield Wipers?
There are different ways you can fix squeaky windshield wipers, and they’re relatively easy to do on your own. Here are some tips you can try out:
#1. Clean Your Windshield Regularly.
When was the last time you cleaned your windshield? If it’s been a while, then this might be the culprit behind your squeaky wipers.
Over time, dirt and grime will build up on your windshield and cause your wipers to squeak. To fix this, just give your windshield a good and thorough cleaning.
#2. Clean Your Wiper Blades.
If cleaning your windshield doesn’t work, then you might be dealing with dirty wiper blades. Dirt, debris, and tiny insects can get stuck on the blades, causing them to squeak every time you use them.
Take a clean cloth and wipe your wiper blades down gently. Be careful not to be too harsh when cleaning them or you might end up snapping your wipers in half. Watch out for things like tree sap, as they’ll kill your blades if you don’t immediately wipe them off.
#3. Replace Worn Blades.
Are your windshield wipers still squeaking even after a thorough cleaning? If so, then it might be time to say goodbye to your wiper blades and get new ones.
Wiper blades naturally wear over time, and when they near the end of their lifetime, they’re less likely to function well. Replace them as soon as you can as driving without functioning wipers can be a huge safety risk, especially when it rains.
#4. Apply a Wiper Blade Lubricant.
Looking for a quick and easy way to fix noisy windshield wipers? Try applying a small amount of silicone-based lubricant to your wiper blades. This should help reduce friction between the blades and the windshield as well as stop that pesky squeaking.
#5. Tighten the Screws on the Wiper Arm.
Usually, windshield wiper arms are held together with a big nut, and the linkage usually has threads and is the mounting point for the arms.
Sometimes, the screws holding your wiper assembly together can get loose, causing your windshield wipers to make an annoying squeaking sound.
To fix this, all you have to do is tighten the screws on the wiper arm.
#6. Adjust the Wiper Blade’s Metal Tabs.
Have you tried checking on your wiper blade’s metal tabs? They might be the cause of all that squeaking noise if they aren’t in the right position.
This might require a little bit of trial and error, but it’s easy enough to do on your own. Look for the squeaky spot on your wiper blades, and gently bend the metal tab in the opposite direction.
When Should You Replace Your Windshield Wipers?
While replacing your wipers can certainly help get rid of that squeaky sound, it shouldn’t be the first solution you turn to. Squeaky windshield wipers don’t automatically mean your vehicle needs new wipers, but it is a good time to check on their condition.
If you notice any damage, then it’s probably time to replace them. Ideally, however, you only need to replace your wiper blades every 12 months.
Of course, this can vary depending on several factors, including how often you use them and your vehicle’s year, make, and model.
It also depends on what type of wiper blades you have on. Some are metal frames with a rubber insert, and some are completely plastic with rubber.
