How to Fix a Slow Car Window?

Is your car window making a squeaky sound once you pull it up? Is its glass sticky and slow to move up and down? If you are experiencing these problems with your car window, there’s a quick and cheap solution for it. It only involves the use of a rag or paper towels and the right lubricant. If you are interested, keep reading below because you will surely learn a lot when dealing with a slow car window!

Recommended lubricant for squeaky, slow car windows

When dealing with a slow and squeaky car window, it’s important to know the right lubricant product for the job. We recommend using a spray silicone grease, which costs about $5 at your nearby hardware or automotive store. A single item can cover 2 to 3 car windows.

Don’t use oily or petroleum-based lubricants as they can catch dust and dirt and accumulate grime over time. Using it will result in an even squeakier and slower car window. These types of lubricants will eventually dry out, causing more damage to the window.

Dry moly lubricant, a spray silicone grease, bonds extremely fast on a metal surface, creating an anti-dirt barrier that lubricates and protects the surface from friction and pressure. This kind of lubricant is safe for use on vehicle parts inside doors and other materials.

Steps in Fixing a Squeaky or Slow Car Window

  1. Spray the moly lubricant on each car window – make sure all of them are fully open. Include both sides of the window frame as well. Start by spraying into the rubber seal from the top of the frame and make your way down. Don’t worry if some of the lubricants will trickle down. You can begin on the window frames on the left side of your car.
  2. Follow the same process in step # 1 on the window frames at the right side of the vehicle. Your lubricant should be properly distributed throughout the vertical frame of the car window, sliding down toward the bottom corner of the glass seal. Spread the lubricant across the door frame or the car’s body using a rug. And don’t forget to work around the window seal as well.
  3. Wait for about 5 – 10 minutes before rolling up the windows to a full close. Open and close your car window a few times to ensure the silicone grease reaches deep into the track. If there’s no longer any squeaky sound, you can stop opening and closing the window.
  4. If you still hear some squeaky sound, spray more silicone lubricant into the window seal with the glass fully closed. Doing so will allow the oil to slide down deeper into the components inside the car door.
  5. Wipe off any excess oil outside the window seal, door frame, or car’s body with a dry rag. While cleaning, try not to let silicone grease reach the bottom portion of the window frame, as this will result in a sticky glass and could make clean-up more problematic.
