Gentlemen, I need help! I have the door panel off (passenger door) but can't figure out how to remove the regulator/motor assy. It's behind a metal structural panel of the door. I even have the GM Shop Manual for it and I Can't figure it out. They say to drill out some rivets but the rivets I see have been put in from the inside or the other side of what I can see. I see some bolts and I guess I could cut the rivets off with a Dremel tool. They say to tape the window in the up position. Does any of this sound familiar to anybody reading? Sure could use some help.
