Help!! Window Pops
When I roll my driver side front window up and down it makes a horrible popping sound and moves around. When the window is halfway down it is very loose, I can move it around with my hand and I can't do that on any of my other windows. It moves like it is out of alignment with a guidance track or something. What could be the problem here and how could I fix it? Someone please help me. I have a 2000 323i sedan.
