I want to figure out what is causing this because it's frustrating. There seems to be something on the inside of the door that rubs against the outside of the drivers side door window and this thing that is rubbing must be covered with dirt because I could clean the window, dry it off, then roll it down and when I roll it back up it has a nice 1"-2" wide vertical stripe of dust/dirt. This will just wipe off because its just fine dirt/dust. What ever this is I think is also scratching it VERY lightly because there are some faint streaks that dont just wipe off. Any ideas. I'm not really to interested into taking the door panel off if I don't know whats causing it, but I can if someone knows what is most likely is then I'll go for it. I'll try to get pics tomorrow.
