Question

Answer
You may need to get a can of sprayable Silicone at your local walmart parts store or wherever. You need one with a small long tube they usually come with one. With the windows down spray a good amount down in each track. {the blank thing that holds the window in place}Do not use grease for that attracts and holds dirt.
