Bring it to an auto repair shop. The window mechanism in the door wears out. Not a very hard job, but you need the right tools (specifically 1 wrench). If this place has the tools, should be no problem. You must buy the whole assembly, not just the one part, I do not beleive it is that expensive. One bolt at the top of door frame behind the window glass (need tool to do) and then two more at the lower end of the door frame. The job is fairly easy and it shouldn't run you too much $. Hope this helps, good luck.
