hey guys it's been awhile since i post a threat. anyways on my 02 civic exi my window whenever i pull it down it vibrates and i have to press against it for the vibration to stop. any ideas as to what could be the problem. pushing the window up is fine.

Has the door been taken apart? There is supposed to be styrofoam inside the door to keep the window from vibrating. Maybe it came loose

theres suppose to be these pieces of Styrofoam that stop the vibration. In your case they might have been taken out or fell out of place

As you're rolling it or whenever it's rolled down? Mine does it when it's rolled down half way. I either have to have it all the way up or down.....or turn the stereo up.
