My mom has a 2000 Saturn LW wagon. While the car was in the hands of the inspector for its annual safety inspection, the interior door handle up and broke. The inspection was being done at a gas station, not at the dealer. The replacement handle should be at the dealer today. This is the driver's side front door. I'd appreciate any advice on the location of hidden screws, retainers, and so forth that have to be loosened so that the door panel can be removed for the handle's replacement. Thanks.
