The right front window of my 98 lesabre is tilted out at top, so when closed, has slight gap, and doesn't seal at top. How can I adjust this? Haynes doesn't cover it. Thank you, Huey

You'll need to remove your door panel and plastic sound insulator to gain access to the window regulator. I don't think these types are adjustable because the glass simply sits on a long support bar on the regulator. If the regulator joints are worn it may cause the misalignment.
