How To Stop Windshield Wipers From Squeaking: 5 Ways To Try!

It is painful when you are on a long road trip because the sound won’t let you relax, listen to music, or focus on the road. How to stop windshield wipers from squeaking? Why do they even make that sound in the first place? Let’s follow along!

Why Do Windshield Wipers Squeak?

Could anything be more annoying than squeaky windshield wipers when you are driving? That awful, repetitive noise is distracting and almost impossible to ignore. 

There could be several possible reasons that cause windshield wipers squeak. It could range from simple dirty wipers to more complicated problems like cracked or worn-out wiper assembly.

The good news is faulty windshield wipers are not a costly or tricky fix but finding the source of the problem requires patience and a couple of trial and errors.

How to Stop Windshield Wipers from Squeaking?

You should not ignore the squeaky wiper blades because the conditions could deteriorate if you don’t fix them at the right time. 

Keeping them running will put extra strain on them, resulting in their failure or damaging the expensive windshield.

So, how to stop windshield wipers from squeaking before they lead to something worse? Follow these tips:

1. Regular Cleaning

One potential cause of squeaky wipers is the deposit of dirt and grime on the windshield. 

A thorough cleaning of the blades and the glass will solve this problem and you should do it at least once a week to prevent it from a recurring issue.

Use an ammonia-free glass cleaner to clean the windshield glass. Spray it on the surface and wipe it clean with a microfiber towel or a squeegee. 

You can apply the same solution to the blades or spray rubbing alcohol or lukewarm soapy water. Lift the wiper blades from the surface and rub the solution on every single crevice.

2. Wiping Wax from Windshield

Some people apply a water-repellent product to the glasses. It makes the raindrops slide across the windshield and improves visibility during wet conditions. If the squeaks started right after applying such a product, then you have to remove it.

3. Top up the Wiper Fluid

Lack of moisture on the windshield glass can also be the reason for bad windshield wipers. Refill the wiper fluid if it is running low or empty. The blades need proper lubrication for gliding across the windshield without making any noise.

4. Fixing the Wiper Blades

How to stop windshield wipers from squeaking? Simple! Replace the wiper blades if they are cracked or worn out. 

Deformed blades cannot slide across the glass surface fluidly. The result is an annoying clattering sound. However, the blades are inexpensive and easy to replace.

Sometimes, squeaks could be the result of the way the wiper assembly is fastened. Too tight or too loose screws can cause that screechy sound. 

It happens due to temperature changes, snow or ice buildups, and debris deposits. You just have to clean the surface and tighten or loosen the screws as required.

5. Replace the Assembly or the Windshield

If nothing works, then the problem is probably with the wiper assembly. Changing the entire fixture will solve the trouble. 

The windshield could be the culprit too as its surface can become rough due to weather conditions and dirt on the road. If a thorough cleaning does not fix this, you have to replace the windshield, which is expensive.

6. Avoid Using Wipers on a Dry Windshield

In case you weren’t aware, a dry windshield should never be cleaned using wipers. Use your wipers sparingly if the rain is not falling heavily enough or there is no wiper fluid on your windshield.

You’ll hear a squeak if you do. Of course, this is the least important issue to be concerned about. Since the windshield isn’t lubricated, the rubber might cause your windshield long-term harm.

In severe circumstances, the windshield will deteriorate to the point where a complete replacement is required. If you use wipers on a dry windshield, it can also lengthen and deepen pre-existing cracks.

7. Inspect Frozen Fluid Nozzles

The fluid nozzles may not actually be spraying wiper fluid onto your windshield, despite what you may believe. When it’s really cold outdoors and your automobile is left parked outside all night, this problem frequently arises.

Look at the hood’s top where it meets the windshield. Two little black plastic pieces with holes towards your windshield should be visible. The wiper fluid is obtained from here.

Check carefully to check whether there is any frost or evidence of freezing. If there is, then use my instructions to safely defrost these nozzles.

8. Secure the Fasteners

There will be fasteners at the bottom of the wiper arm arms and occasionally in the middle of the wiper blade housing. These protect the assembly and make sure nothing brushes up against anything else.

You may be hearing a squeak because these fasteners may be loose if you hear that. The next step is to locate the fastener and the appropriate tool to tighten it.

Your automobile and the kind of windshield wipers you have will determine the tool you require. You likely need:

  • A hexagonal aperture on the fastener, an Allen key
  • A screwdriver for fasteners with slots or X-shaped slots
  • If the fastener has an outside hexagon, use a socket set.
