How to remove the door panel on 1999 Buick LeSabre?
Using a screw driver, remove the screws and the clips that are in the door panel. Gently pull the door panel away from the frame, remove any wire connectors and the door panel should be free.
There are really very few differences. For 1998 all US market new vehicles got second generation airbags standard. The 1997s had first-gen bags. Also, OnStar was an option in Lesabres starting in 1998. Other than for those to items and possibly some paint and pricing differences, a 1997 is the same as a 1999 Lesabre.
