If your car’s windows make a “squeaky” sound when you roll them up or down, there’s a good chance that they’re not sealing properly. Here’s how to fix the problem:

  1. Check the window washer fluid level. If it’s low, add more to the reservoir.
  2. Clean the window tracks and rollers with a clean cloth or a vacuum cleaner with the hose attachment. Make sure to get behind the track and around the roller.
  3. Apply a thin layer of window sealant to each side of each window track and roller using an applicator that comes with the sealant. Be sure to apply enough sealant so that it covers both sides of each track and roller completely. Let the sealant dry for at least 30 minutes before rolling up or down your windows. ..
