Front Door Weatherstrip: Service and Repair
Weatherstrip Replacement - Front Door Opening
Tools Required
J 38778 Door Trim Pad and Garnish Clip Remover
Removal Procedure
1. Remove the interior garnish moldings.
2. Use the J 38778 in order to pull the weatherstrip from the pinchweld flange of the door. Start at the upper right corner (6), and pull the
weatherstrip down (5,4). Keep pulling the weatherstrip (3) until you reach the top (1) of the door, and have pulled the weatherstrip free.
Installation Procedure
Important: Ensure that the weatherstrip length is equally distributed around the door opening.
1. Partially attach the weatherstrip to the pinchweld flange in 6 key areas (1,2,3,4,5,6).
Important: Fit the weatherstrip to the opening by hand.
2. Seat the weatherstrip onto the pinchweld flange to approximately 154 mm (6 in) on each side of the corner in order to install the weatherstrip at
each corner (6,4,3,1).
Important: Use a rubber mallet and hit the weatherstrip square to the flange. Otherwise, an undesirable spreading of the carrier will
occur that will result in reduced retention.
3. Use a rubber mallet in order to install the weatherstrip into each corner.
4. Use a rubber mallet in order to install the pinchweld flange areas of the hinge and the windshield pillars.
5. Ensure that the following conditions are met:
*
The weatherstrip fits into the corner and matches the radius of the pinchweld flange.
*
The weatherstrip is seated completely onto the flange in all areas, resulting in a smooth vinyl-trim around the entire door opening.
*
There is not any distortion or excess spreading of the carrier as a result of hitting the carrier improperly with the rubber mallet.
*
The weatherstrip is not kinked or distorted after installation.
*
The weatherstrip is lubricated with GM weatherstrip silicone lube. Refer to Fluid and Lubricant Recommendations in Maintenance and
Lubrication.
