5 Easy Steps to Fixing a Slow or Squeaking Car Window

Is your car window slow and dragging, or does it squeak so loudly that it sends shivers down your spine every time you try to roll it down? If so, you’re not alone. Squeaking car windows are a common problem that many car owners face at one time or another. But don’t worry; fixing a slow or squeaky car window is often super easy and inexpensive.

In this article, we’ll walk you through a simple step-by-step guide on how to fix a squeaky car window and also give you a few tips on how you can prevent it from happening again. So with no further ado, let’s get started!

Why is my Car Window Squeaking?

While a squeaky car window can be caused by a number of things, such as debris or dirt caught in the track, a lack of lubricated window seals, worn or misaligned window components, or due to corrosion.

9 out of 10 times, it’s caused by the first two mentioned, which is what we’ll cover first. And if not, we’ll cover how to proceed from there.

So, first of all, dirt, grime, and other debris can easily accumulate on the window and the window seal, which can cause the window to squeak as it moves up and down. Especially if you rarely wash your car.

But following our guide on lubricating your window seals, it usually takes care of this issue too.

Now, if you have never heard about lubricating window seals, you’re not alone. This is not something that you usually have to do if the window is not sticky or squeaking. However, we always advocate taking extra care of your car since we think TLC is very important.

Lubricating the window seal is one of those things we recommend doing as soon as you notice any signs of dry seals, such as a squeaking noise. So let’s go over how to properly lubricate it.

How to Fix a Squeaky Car Window

Here is a step-by-step guide on how to lubricate your car windows in 5 easy steps:

What you need:

  • Silicone grease spray
  • A clean rag

1. Begin by fully opening the window that is making the squeaking sound.

2. Generously spray the inside of the seal on both sides of the window frame, starting at the top of the left side and working your way down. Repeat this process on the right side. Make sure the lubricant is applied evenly all over the seal.

3. Use a rag to wipe and clean away any excess lubricant from around the window seal.

4. Let the lubricant sit for a few minutes, then try rolling the window up and down a few times. The squeaking sound should be improving.

5. If the problem persists, repeat the process once more.

After the squeaking stops, let the lubricant dry for a few hours and then make sure to clean any leftover lubricant thoroughly.

Place your index finger into the piece of cloth and press down the seal as far as possible to clean the bottom of the window frame of excess lubricant. 

However, if the squeaking isn’t completely gone, other issues may be causing it. So if this is the case, you should start by looking into the option of a loose component or malfunctioning window regulator motor. 

But to do this, you need to be able to remove the door panel and sometimes drill out a few rivets. This process is usually a little bit different for each vehicle out there.

But once the door panel is gone, you can inspect and test tightening the window regulator to see if it gets better.

But if you’re unsure how to do this or if the regulator needs to be replaced. You may want a mechanic to assess the issue and recommend a solution.

How to Prevent Car Windows From Squeaking

To prevent the car window from squeaking in the future, simply follow the tips we already mentioned before. This includes keeping your car windows clean by washing your car regularly. Every two weeks or so is usually a good rule of thumb.

Secondly, as soon as you notice any signs of dry window seals or squeaking noises, spray a new round of silicone lubricant by repeating the step-by-step guide above. In some cases, this actually needs to be done every month to avoid the squeaking noises from coming back.

What Kind of Lubricant Do You Use for Car Windows?

It’s important to use a lubricant that is specifically designed for use on car windows and their tracks. This is because other types of lubricants, such as oil-based lubricants, can attract dirt and debris, which can cause the window to become even more difficult to move over time.

Silicone-based lubricants are a good option for lubricating car windows. They are effective at reducing friction and are resistant to water, making them well-suited for use on car windows and their tracks. They are also long-lasting and won’t attract dirt or debris like some other types of lubricants can.

There are also lubricants on the market that are specifically designed for use on car windows and their tracks. These lubricants may contain a combination of silicone and other ingredients that are formulated to provide lubrication and protect against rust and corrosion. 

This type of lubricant costs around $5 to $10 and can be found at your hardware store or most automotive supply stores, as well as online retailers such as Amazon. One can usually is enough to fix 2 to 3 windows.


Can You Use WD-40 on Squeaky Windows?

While it may work to lubricate the window for a short period of time, it is not recommended to use silicone-free WD-40 on any window seal, no matter what anyone says.

Most car window seals are made of EPDM rubber which will swell and dissolve by the petroleum in the WD-40 spray. Instead, use a silicone-based WD-40 spray or other silicone grease spray that is designed for use on car windows.

How Much Does a Can of Car Window Lubricant Cost?

A can of car window lubricant usually costs around 5$ to 10$ and can often be found at your closest hardware store or most automotive supply stores. You can also buy it online from retailers such as Amazon. For a whole car, you’ll want to buy two cans of lubricant.

Is It Normal for Car Windows to Squeak?

It is not uncommon for car windows to make some noise when they are being rolled up or down, especially if the car is older or has not been well-maintained.

However, excessive squeaking or grinding noises may indicate that there is a problem with the window mechanism or that the windows need to be lubricated. Lubricating a car window is very simple and inexpensive, so start with that.

Can a Squeaky Car Window Be a Sign of a Bigger Problem?

While the most common reason a car window squeaks is a lack of lubrication, it can be a sign of a more serious issue, such as damaged or worn parts in the window mechanism.

In this case, you need to remove the door panel to assess its condition. If this is something you’re not comfortable doing yourself, you’ll need to have a mechanic inspect it and determine the necessary repairs for you.

To Sum It Up:

Squeaking car windows can be just as frustrating as squeaking brakes. But since a car window squeak is often caused by dry seals or debris and dirt stuck in the track, it’s often a quick and easy fix. Simply follow the guide we discussed in the article and lubricate the seals generously. Do not forget to clean excess grease thoroughly.

If the squeak doesn’t go away, it may be a more serious issue, such as a malfunctioning or damaged window mechanism, and may require the assistance of a mechanic. To prevent car window squeak, wash your car regularly and lubricate the seals and tracks as needed. Thanks for reading!
