How to Know When to Grease Your Car's Window Regulator

Car window regulators are a complicated part of your vehicle. They work to lift and lower the windows, but they can also wear out over time. If you want to keep your car running smoothly, it's important to know when to go for the window regulator grease.

But, when should these greasing be done? There are several signs that indicate that your car's window regulator needs a grease job. If any of these problems occur, visit a professional repair shop as soon as possible.

Sticky or Slow Windows

If your windows are slow to roll up or down, you may need to grease the window regulator. This is a fairly simple process that can be done in less than an hour. Since the window regulator is responsible for raising and lowering your windows, this is one of the first things you should check when troubleshooting window problems.

There Is Slippage When You Roll Down the Window

If your window moves through its track smoothly but you feel some resistance when you roll it up or down, then it's more than likely that you need to grease the window regulator. If this happens only rarely, then it may just be due to dust build-up. In this case, simply give the regulator a good cleaning with a relevant lubricant spray and see if that makes a difference.

You Have to Force the Window Open or Closed

If you have to use force when opening or closing your car's windows, then chances are good that they need greasing. This problem can happen if there's too much friction between the glass and the regulator arm while they're moving in their tracks.

Excessive noise when closing or opening your windows

A good way to tell if your window regulator needs to be greased is if it makes excessive noise when rolling up or down. If this is the case, then there's probably dust and dirt between the gears causing friction and making noise as they move around each other. This can be dangerous if left unchecked because it puts extra strain on the motor which could cause it to fail prematurely in an accident or roll down while driving!

Your Car has Manual Windows

If you've ever owned a car with manual windows, you probably know that there's a lot of friction when you roll the window up or down. This is because there are two parts: the regulator—which stays in the door—and the track that moves back and forth on it. The regulator has pivot points that allow for different amounts of window movement, and it's designed to move smoothly. But over time, dirt and debris can build up between these parts, causing them to bind together. This can make it difficult to roll your windows up or down! So, The most common maintenance issue with manual windows is their inability to remain closed when rolled all the way up, so you'll need to grease your car's window regulator regularly to keep it working properly.


Think about the maintenance you do to your car. Lubrication is very important. Your window regulator is an expendable part of a mechanism, and it needs maintenance. If it fails, you will have to replace the part and pay for labour. The best thing to do would be to take care of it before you get anything like that happening. A little time spent on something as important as a window regulator is worth it.
