Install the screws that retain the panel to the door.
Tighten

Tighten the screws that retain the panel to the door to 2 N.m (18 lb in).
Install the swing-out window latch. Refer to WINDOW REPLACEMENT - SWING OUT in Stationary Windows.
Ensure that the weatherstrip fits into the corner and matches the corner of the radius of the body flange.
Ensure that the weatherstrip is seated completely onto the flange in all areas, resulting in a smooth, vinyl trim around the entire door opening.
Important: When using the rubber mallet, the weatherstrip must be hit square to the flange. Otherwise, an undesirable spreading of the carrier will occur, resulting in reduced retention.
Ensure that there is no distortion or excessive spreading of the carrier as a result of hitting the carrier improperly with the rubber mallet.
Lubricate the weatherstrip with GM Weatherstrip Silicone Lubricant P/N 12345579 or equivalent.
