Customer Satisfaction 00006 - Rear Window Assembly Water Leak

General Motors has decided that certain 2000 Chevrolet and GMC S/T pickup trucks equipped with a stationary rear window and built at Shreveport Assembly Plant may have been built with the urethane adhesive bead off-location in the area where the lower left-hand corner of the rear window is affixed to the window flange. This bead of adhesive may not have made full contact with the window flange, resulting in a possible water leak.

Dealers are to apply urethane adhesive into the joint of the leak area.

Involved are certain 2000 Chevrolet and GMC S/T pickup trucks equipped with a stationary rear window, built at Shreveport Assembly Plant, and built within the following VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved.]

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

Before performing this procedure, review the Stationary Glass sub-section of the Service Manual for additional information and drying times. Also, refer to the Interior Trim sub-section of the Body and Accessories section of the Service Manual for information of trim removal, installation, and torque specifications.

In addition, review the instructions included with the Glass Urethane Adhesive Kit (P/N 12346392) before proceeding.

1. Remove the left side carpet sill plate.

Important: On extended car models WITHOUT the left side third door, it is not necessary to remove the folding seat assembly in order to remove the C pillar garnish molding in the next step.

2. Remove the interior C pillar garnish molding from along the left side of the backglass.
3. Remove the interior garnish molding below the rear backglass.



4. From the inside of the vehicle, inspect between the lower left corner of the backglass frame and the sheet metal pinchweld for missing urethane adhesive. The area to inspect is approximately 50 mm )(2 in) long extending upwards (vertically) from the lower left corner and approximately 50 mm (2 in) towards the center of the vehicle (horizontally). Refer to Figure 1.

Important: If urethane is NOT missing, proceed to Step 8 and apply an additional bead of urethane in the area shown in Figure 1.

If urethane IS missing, proceed to Step 5.

Important: It may be necessary to trim the daubers used in the next steps in order for them to fit between the backglass frame and the sheet metal pinchweld.

5. From inside of the vehicle, using water and one of the daubers supplied in the Glass Urethane Adhesive Kit, clean the area between the backglass frame and the sheet metal pinchweld where the adhesive is missing.
6. Using compressed air, dry the area between the backglass frame and the sheet metal pinchweld.

Important: Shake or agitate the primer thoroughly before applying it in the next step.

7. Using another clean dauber, apply PVC primer (clear #4) supplied in the kit to the backglass frame where the adhesive is missing.
8. To ease clean up, apply masking tape as necessary to the inside sheet metal around the lower left corner of the backglass where the adhesive will be added.
9. To ease clean up, apply masking tape to the inside of the backglass at the lower left corner as shown in Figure 1.
10. If urethane IS missing, cut the end of the applicator tip as necessary to apply a 4 mm wide continuous bead of the urethane adhesive supplied in the kit, between the backglass frame and the sheet metal pinchweld in that area.
11. If urethane is NOT missing, cut the end of the applicator tip as necessary to apply a 2 mm wide continuous bead of the urethane adhesive supplied in the kit, over the original urethane in the area shown in Figure 1.
12. Using a flat-bladed tool, paddle the urethane into the area and smooth.
13. Remove the masking tape from the backglass frame and the sheet metal. From outside of the vehicle and using a light stream of warm water, test the area for water leaks.
14. Install the interior garnish molding below the rear backglass.
15. Install the interior C pillar garnish molding along the left side of the backglass.
16. Install the left side carpet sill plate.
