Look at your CD ROM manual and find Job # 72-195. It is in the chassis section for doors. There are plenty of photos to assist in fixing your problem and show you what adjustment point to use for a specific movement of the window assembly. But, as others have cautioned, go slow, use care and remember that small increments of adjustment are the best course to take.

Group 72 deals with the doors. Plenty of information there, and many ways to get in over your head, so take it easy. While you have the door apart, make sure the tracks and gears are lubed. Old grease can make things stiff and sticky.
