Gap Between Primary Weatherstrip and Lower Rear Quarter Trim Panel (Install Foam Block)

Some customers may comment on a gap between the weatherstrip and the lower quarter trim panel ("D" pillar) at the base.

The door weatherstrip may have dropped down below the quarter trim panel instead of sitting on top of it.

Inserting the foam block behind the quarter trim panel will keep the weatherstrip from dropping down below the trim panel instead of sitting on top of it.

1. Remove the sill plate, liftgate weatherstrip and pull the quarter trim outboard at the base of the "D" pillar just enough to insert the foam block.
2. This insulator is used for another part of the vehicle and it will be necessary to cut 10 mm (3/8 in) off the top of the foam block for it to fit this correction.
3. Bend the foam into a "banana" shape to match the floor plan curvature.



4. Insert the foam block at the base of the "D" pillar. Press/rub the foam to ensure a good bond.
5. Push on the quarter trim panel to make sure it is seated and reinstall the weatherstrip and sill plate.

Important:  There may be two parts per package although only one piece is required per side. GMSPO is working on this and it should be corrected shortly.
