Well...I have actually taken the door panel off mine and have actually seen in there. I cleaned everything with brake cleaner spray and a 1" paint brush, then let it dry for 30 min.
I then used some synthetic brake caliper grease to lube things. (After having repaired and adjusted and lubed over 50 windows (@ 2 hrs labor charge), I have found syn. grease to be the best. It will stay plyable, even at 1,000,000* below freezing.:biglaugh: Get it at any parts store in a toothpaste type tube.
Yes, there are some adjustments you can make inside the door frame. You'll have to plug the power back up to the switch to roll the glass up and down as you inspect and move some of the adjustments to get the best fit.
Tighten the nuts good when you are done.
It is something you'll just have to see when you get in there. Not too hard, just a bit of a puzzle at first.:aigo:
