Fix a Squeaky or Slow Car Window in 5 Easy Steps
Does your car window make a lot of noise when you roll it up? Is the glass slow or sticky as it rises? You can easily fix a squeaky or slow car window with just one product and five easy steps.
There is a quick, cheap solution. All you need is the right lubricant and a rag or a roll of paper towels.
Best Lubricant for Squeaky or Slow Car Windows
For this job, it’s important to use the right product. To fix a squeaky car window, we recommend using spray silicone grease. A single can should cost about $5 at your local hardware or automotive store and has more than enough product to fix 2 to 3 windows.
Avoid using any oily or petroleum-based lubricant because it will capture dirt and dust and, as it collects grime over time, the problem will get worse. The buildup will actually cause the car window to be even noisier and slower than before. Additionally, over time, these types of lubricants dry out the felt and rubber surfaces in the window tracks and may cause further damage.
Dry moly lubricants, like spray silicone grease, bond instantly with metal surfaces to create a dirt-repelling shield that lubricates and defends the surface from friction and pressure. Most importantly, this type of lubricant is safe for use on metals and the other materials of automotive components found inside the door.
5 Steps to Fix a Squeaky or Slow Car Window
- With the vehicle’s window fully open, you’re going to spray the moly lubricant inside the seal on both sides of the window frame. Start on the left side of the window. Spray the moly lubricant into the rubber seal from the top of the window frame and work your way down. Some of the excess will slide down inside the seal, that’s fine.
- Repeat this process on the right side of the same window. Make sure that the lubricant is well distributed all down the vertical frame of the window, reaching down to the bottom corner of the seal. Use the rag to wipe around the window seal, door frame or body of the car.
- Wait a few minutes, then roll up the window. Make the glass go up and down two or three times to ensure that the silicone grease gets down into the track. The squeaky sound should improve each time.
- If the squeak isn’t completely gone yet, you can add more spray silicone lubricant into the seal of the window with the glass all the way up and this will help transfer the lubricant down into the components inside the door of the car.
- Repeat steps 1 through 4 until your car window is completely squeak free.
Keep a rag handy to clean up any excess lubricant spray on the outside of the window seal, door frame or body of the car. You want to avoid getting the silicone grease into the bottom horizontal part of the window frame because this will cause the glass to be streaky and could make cleanup more difficult.
It’s easy to clean up after this process. You should wait at least a few hours, giving the lubricant time to dry completely.
First, use paper towels or a rag to wipe all around the rubber seal of the car window and anywhere else you see leftover silicone lubricant. Then, place your index finger into the rag and use it to clean the bottom horizontal part of the window frame. With your finger press down into the seal as far as possible. Finally, clean the glass with a basic glass cleaner and paper towel.
