The window regulator is going to be broken and will require replacement. Do you have tools and a place to work? The regulator itself lists for $166.16 and the part number is 51-33-8-252-393 and can be purchased online at Realoem.com. As far as easy goes, I dont think it is difficult, but then again I have replaced several hundred of them. Let me know when you need a step by step and we can continue.
