Something is wrong with my driver's side window. The motor is fine and all I know that but when I try and roll it down it seems to get caught on something(could be wrong, don't know) and it stops rolling down at a certain point. Has anyone else had this happen, or better yet know how I could go about fixing it? I'm on a college budget so I'd really like to fix it myself :D But if required I will take it to a shop. Thanks.
