You would need to remove the inner door trim panel and see if the window regulator of window channel is damaged in any way. Illustrations are needed to remove the trim panel so nothing gets damaged. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
It's hard to just guess what is wrong without being able to take the door apart and examine the problem first hand.
