New to this forum but figured maybe someone could help. I have a 2004 Mustang
V6 w/ automatic. The driver side window streaks badly on the inside when rolled up. I'll clean the window spotless and then the next time I roll it down and back up, it's covered in vertical streaks. They wipe off and have kind of a waxie consistency to them, as opposed to gritty or greasy but once I roll it down and then back up again, more streaks. Obviously something down inside is rubbing on the window but I'm not that knowledgable about the inner workings of the door, so I have no idea what. Any suggestions would be appreciated.
