Condition
Some customers may comment that the front floor carpet is wet.
Cause 1
© 2016 General Motors. All rights reserved. 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. Refer to the illustration above.
Cause 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. Refer to the illustration above.
