Squeaking Car Window: Why is That & How to Fix it?

If you are interested in getting the answer to a basic question like “why is my car window squeaking?” this article delves into the basics and provides insight about what needs to be done for getting rid of the irritating sound.

I enjoy DIY projects and do the majority of my car’s work on my own, so I can easily answer questions like this.

Why is Your Car Window Squeaking?

The primary cause of car window squeaking is dryness. When a new car is delivered from the factory, the automaker inserts a lubricant that reduces friction and enables the window to move up and down without any noise. The lubricant eventually dries up, causing the window to rub against the hard structure of the door, resulting in a squeaking sound.

When the window is rolled up and down several times, the squeaking sound becomes more common as it consumes any leftover lubricant, and the abrasions caused as a result harm the glass of your car’s window.

How to Fix a Squeaking Car Window?

Fixing a squeaking car window is a simple process that can be easily performed by anyone. Here are the different steps of the process, however, it is vital to perform them in the right order to achieve the best results:

  1. Get a silicone-based lubricant;
  2. Ordinary WD-40 can be used, but it is not recommended as the primary use of WD 40 is related to metallic parts, and thus it can cause scratches on the glass;
  3. Roll the car window all the way down. You should not be able to see any part of the car’s window;
  4. Lubricate the lower and side sections of the window. However, for best results, lubricating the top section of the window is also recommended;
  5. Apply the lubricant in abundance to ensure that the problem doesn’t pop up again for a long time;
  6. Roll the window up and down at least two or three times to fully drench the dried out parts with lubricant;
  7. The squeaking will subside initially, and after a while, it will vanish completely.

For How Long Will It Help?

If an ample amount of silicone-based lubricant is used, it will eliminate the problem for at least a year. However, if the lubricant was not properly sprayed or was applied in small quantities, the issue is likely to reappear within a few months.

For how long the problem won’t pop up again also depends on the quality of the lubricant under consideration. In case of a substandard product, expect to bear the squeaking sound any time soon. The reason is that this solution will soon evaporate, and thus the problem will quickly reappear.

It also depends on your location’s climatic conditions. If you live in an area with dry air, the screeching sound is more likely to reappear sooner than if you live in an area with moist air. Similarly, the problem is less likely to resurface quickly in colder environments than in hotter ones.

So, in short, how long the lubricant will help you depends on a variety of factors, but one thing is certain: the use of proper silicone-based lubricants is essential which promises to assist you in getting rid of the squeaking car window sound that has been irking your ears.

Can WD-40 Be Used for Reducing the Squeaking Car Window Sound?

A common question among those considering doing this as a DIY project is whether or not WD-40 can be used to remove the annoying squeaking car window sound.

To answer this question, we must first recognize that a squeaking window is not the same as squeaking metallic parts of a vehicle, the problems of which can be easily resolved with a can of regular WD-40.

However, because the regular version of WD-40 is a water dispersant, it is ineffective for squeaking car windows. Being a mixture of oils and solvents, the WD-40 spray evaporates after a while.

You need a relatively permanent solution for a squeaking car window because you can’t keep applying the lubricant over and over. This is why all lubricants containing silicone work for the purpose and last longer.

If you’re looking to solve this problem, you should get the WD-40 Water-Resistant Silicone Lubricant.

So, in simple terms, the ordinary WD-40 that we use for everyday tasks will temporarily solve the problem, but it will resurface after a while, and you will have to repeat the above steps.

Consider using the silicone-based version of WD-40 to remove the squeaking car window sound for a long-lasting solution.
