Your window motor is toast, I had the same issue a few months ago, two hours later, VOILA! Window Motor Re pair Link
Now, I got the Siemens window motor from Autozone for $55 plus shipping and it has a lifetime warranty. You can do it yourself, click link above for EXCELLENT walk through! Took me two hours first time, next time it won't take as long. Would not suggest taking it to a shop/dealer, your gonna get nailed with an hourly rate. I was quoted 3 hours @ $75/hour. plus the part.
Good luck! Report back when fixed!
