There seems to be two small problems with my dirver side window. One, being that whenever I put the window up towards the end of closure the window seems to go out of alignment. For some reason the window just doesn't align up correctly and I would have to put the window down a little bit and then back up to correct this problem. Secondly, my ever I lower or bring the window up I kind of hear scratching noise like as if there is rocks or dirt coming from somewhere. I was thinking that maybe the window seal might need cleaning or replacing. My question is has any of these other problems happened to anyone else and how do I go out fixing these problems?

Thank you in advance for all your replies/help

first of all i wouldn't try to fix it yourself as could the cable might be splitering..and second if you don't know someone that has fixed there's as that cable my be splintering and very dangerous...if you know no one let dealer handle it..be safe.....
