Service Procedure
1. The adhesive surface must be clean, dry and free of dirt or contaminants. Clean the door surface (around the perimeter of the water deflector) with one of the cleaners listed below, or equivalent.^ 3M(R) General Purpose Cleaner, P/N 08984
^ Dominion Sure Seal, Sure Solve Stock BSS
^ Kent Acrosol(TM)
2. Install the water deflector to the inner panel.
3. Pull the harness connectors through their respective holes or slits.
4. Position the outer perimeter of the deflector to the door inner panel by working from the bottom center outboard. Make sure the butyl adhesive is below the drain holes.
5. Using a 50.8 mm (2 in) wallpaper roller, roll out the butyl adhesive. Start at the bottom center and work outboard, up the right and left sides. A 50.8 mm (2 in) roller can be purchased at a hardware or wallpaper store.
Condition
There is water in the rear floor foot well (T-top models).
Correction
The upper "B" detail can allow water to stand and fill the lower weatherstrip. This can be too much water for the drain holes to accommodate. The upper "B" drain must be clear of debris. With the door open and using a squeeze bottle to fill the weatherstrip with water, the water should flow from the bottom drain holes. Refer to Figure 4. If too much water is entering the rear "B" detail, the T-top may not be sealing against the rear sealing strip. If the rear is sealed properly and there is still too much water entering the drain, enlarging the drain holes at the bottom of the weatherstrip will help. DO NOT PUNCH A DRAIN HOLE IN THE SIDE OF THE WEATHERSTRIP AS THIS WILL PROVIDE A PATH FOR WINDNOISE.
Condition
The driver's floor is wet (convertible, hard top, T-top models).
Cause
1. The hood release cable may not be sealed at the front of dash. Refer to item 1 in Figure 5.
2. The body harness grommet may not be sealed. Refer to item 2 in Figure 5.
Correction
Make sure both are SEATED properly. if necessary. seal with GM Weatherstrip Adhesive, P/N 12345097 (in Canada, use P/N 10953479).
Condition
The molded weatherstrip detail at the base of the windshield may not be properly sealed causing the front floor to be wet (hard top, T-top models).
Cause
The material sealing the weatherstrip detail to the body surface between the pillar retainer and the mounting flange on the hinge pillar may be mispositioned or missing.
Correction
Apply a new seal using GM Silicone Sealant, P/N 12345739 (in Canada, use P/N 10953541), as shown in Figure 6 (almost a straight line from the outer edge of the pillar retainer to the inner hinge pillar flange should be used) and reinstall the weatherstrip to the flange retainer.
Condition
The front roof gutter molded weatherstrip detail to the roof sheet metal may not be sealed properly (T-top models). Water entering this area usually runs down the "A" pillar and ends up on the carpet below the instrument panel.
Cause
^ The weatherstrip molded detail may not be sealed to the sheet metal gutter.
^ Small holes or tears may exist in the molded detail at the attaching insent.
Correction
1. Apply a new seal using GM Silicone Sealant, P/N 12345739 (in Canada, use P/N 10953541), to the end of the roof gutter, under the molded weatherstrip detail, as shown in Figure 7.
2. Apply an even amount of GM P/N 12345097 (in Canada, use P/N 10953479) or 3M P/N 08011, or the equivalent, to the hole or tear for sealing.
Condition
The rear roof gutter molded weatherstrip detail to the roof sheet metal may not be sealed properly causing water leaks (T-top models).
Cause
^ The weatherstrip molded detail may not be sealed to the sheet metal gutter.
^ Small holes or tears may exist in the molded detail at the attaching insert.
1. Apply GM Silicone Sealant, P/N 12345739 (in Canada, use P/N 10953541), to the end of the roof gutter, under the molded weatherstrip detail, as shown in Figure 8.
2. Apply an even amount of GM P/N 12345097 (in Canada, use P/N 10953479) or 3M P/N 08011, or the equivalent, to the hole or tear for sealing.
Condition
The molded weatherstrip detail at the base of the lock pillar may not be sealed properly causing windnoise and/or water leaks (hard top, T-top models).
Cause
The material sealing the weatherstrip detail to the body surface between the lock pillar retainer and the mounting flange on the quarter panel may be mispositioned or missing.
Correction
Apply a new seal using GM Silicone Sealant, P/N 12345739 (in Canada, use P/N 10953541), as shown in Figure 9 (apply in a straight line from the inner edge of the lock pillar retainer to the base of the mounting tab and then 90 degrees inboard to the lock pillar flange) and reinstall the weatherstrip to the flange and the retainer.
Condition
Water leaks through the front floor and/or windnoise through the door.
Cause
The door wiring harness rubber grommet may not be seated properly. Refer to Figure 10.
Correction
Make sure the grommet lip is seated properly to the door and the "A" pillar.
Condition
There is windnoise and/or water leaks in the rear of the vehicle (convertible, hard top, T-top).
Cause
The weatherstrip in the area indicated shows where the weatherstrip relaxes and loses contact with the door glass. This generates windnoise. Refer to Figure 11.
Correction
Loosen the "B" pillar weatherstrip retaining screw and tighten the screw while holding the weatherstrip.
Condition
There is windnoise and/or water leaks in the front or rear at the door belt line (convertible, hard top, T-top models).
Correction
1. Insert the push-in retainers. Refer to Figure 12.
2. Ensure that the muket has no folds. Refer to item 1 in Figure 12.
3. Ensure that the muket is in contact with the side door glass when the door is closed. Refer to item 2 in Figure 12.
Condition
There is windnoise and/or water leaks at the T-top butt joints.
Cause
^ The butt joint surfaces between the panel and the body details may have improper contact.
^ The door glass may not be adjusted properly for height or "tip in" contact.
Correction
1. The T-top rail weatherstrip is movable in the retainer and should be adjusted to only slight interference on the front and rear edges. The pressure of the closed glass will increase pressure on the joint once the glass is closed. Too much interference will cause the butt joint to pucker and provide a water path. Refer to Figure 13.
2. Adjust the door glass to obtain sealing in the butt joints. Refer to General Information on Door Glass Adjustments later in this bulletin.
Condition
There is windnoise and/or water leaks from the front or rear "butt" joints (T-top models).
Cause
The T-top may have been installed improperly. Refer to Figure 14.
