Condition:

Some customers may comment that the front floor carpet is wet.

Possible Cause:

Water intrusion at the A-pillar.

Correction:

One or more locations at the A-Pillar will need to be inspected and repaired for water leaks.

Service Procedure





1. Water may enter a hole in the seam sealer at the roof panel to upper "A" pillar post. In this case, the water enters the hole and leaks down the inside of the "A" pillar and ends up on the front floor (see figure 1).





2. Water may enter the seam at the top of the "A" pillar. In this case, the water enters where the roof panel to upper "A" pillar meet and follows this seam under the windshield urethane. The water then drips onto the "A" pillar garnish molding and ends up on the floor (see figure 2).





3. There may be a lack of sealer under the "A" pillar reveal molding push nuts. Refer to the illustration above.





4. The push in retainers at the base of the auxiliary weatherstrip may not be seated fully. Refer to the illustration above.





5. There may be a gap between the many pieces of sheet metal under the primary seal flange. If this is present, water may enter under the primary seal retainer and into the vehicle between the gaps in the sheet metal flange and end up under the carpet. Refer to the illustration above.

Correction 1

Remove the auxiliary seal and the auxiliary seal retainer. Clean the surface and fill the void with Medium Body Seam Sealer, P/N 8-12378-500-0. Let stand for 60 minutes and touch up.

Correction 2

Remove the auxiliary seal and the auxiliary seal retainer. Clean the area with a non oil base cleaner and fill the void with urethane sealer.

Correction 3

Install four new plastic nuts in the "A" Pillar. The new nuts have a foam gasket that seals the perimeter when seated.

Correction 4

Seat the push in retainers fully at the bottom of the "A" pillar.

Correction 5

Apply weatherstrip adhesive inside the primary seal retainer. Seal the retainer from the top of the dash to the bottom of the "A" pillar.
