RE: power window switch removal
The rails are the track that the window lifters roll on, inside the door (kind of looks like a scissors jack). You'll have to remove the interior door panel and the plastic film that keep the moisture out (if you're careful you can reuse it.) Don'tuse axle or bearing grease or the inside of the truck will smell to high holy hell.Use something like white lithuim grease. you canpick a spray can of that upat HD or Lowes for about 4 bucks.
