This PI was superseded to include new fix information. Please discard PIT4708.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may comment that there is a white residue on the carpet or seatbelt of their Colorado or Canyon (Refer to the illustration above). Typically the stain is noticed at the seatbelt base where the seatbelt is anchored into the floor pan. This may be the result of water working its way between "tabs" and between the hem flanges at each door opening.

1. Remove the sill plates and expose the hem flange at each door opening. Unclip the wire harness as needed.



2. Apply sealer along the top of the hem flange to seal any voids where the sheet metal ends come together (reference number 1 in the illustration above). The sealer should run the entire length of the hem flange of each door opening along the sill plate area.



3. Locate the tab(s) along the hem flange called out as number 1 in the illustration above. Seal the areas called out as number 2 in the illustration above at each tab on the hem flange. This area should be sealed from the inside of the vehicle, starting at the bottom of the tab working your way toward the top of the hem flange.
4. Allow the sealer to dry and then reassemble the trim.

Noti: This should be done at each door opening on each tab. The number of tabs may vary between vehicles.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
