Driving home yesterday from work I put my drivers side window down. They are power that is! As it was going down I heard something in the door and the window jolted? I can not not put it up nor down but only in 1 inch spurts. I can lift the window up and down about 4 inches? What could have happened?

I see the forums are changed a bit and I did a search to find nothing on this topic?

Thanks for any info you could give me or advice??
