Hey,
Ive had rattling windows in a couple of doors for sometime now.
When closing the door you could hear a glass rattle sound, which was ALWAYS very annoying. I even thought that it might possibly lead to a cracked window which makes it become an even larger problem. Soooo
Today i opened up the door panels andit turns out that the channel that supports the bottom of the glass had lost its gasket, or insulator , and I realized that this became a rather easy fix.
Also gave me the opportunity to grease and lubricate all the moving parts too.
