Front windows wont roll all the way down

I recently picked up my 635 and found this great forum. My problem is neither of my front windows goes all the way down. The drivers stays up about 1" and passenger about 1/2 ". I searched and found threads on adjustments but I couldn't find anything about my particular problem.
I figured before I tear into it maybe somebody has had a similar problem or could point me in the right direction
Thank you in advance.
