Procedures 1 - 13
Condition # 1The customer may comment of water anywhere across the top of the windshield.
Cause
Plan-A top built before December 2005: During a torrential rain storm the drain hole in the weatherstrip may not be large enough to accommodate all the water.
Cut a longer thin 30 mm (1-1/8 in) slit in the weatherstrip. The left hand illustration above shows the original weatherstrip while the right hand illustration shows the slit cut in the weatherstrip to the end of the square mold lines.
Cut a 3 mm (1/8 in) wider piece of weatherstrip out of the bottom of the weatherstrip.
Plan-A and Plan-B Weatherstrips: Make sure that the windnoise weatherstrip located on the front edge of the door is not blocking the drain opening of the windshield weatherstrip.
Relocate the weatherstrip so there is an approximate 5 mm (1/4 in) gap between the windnoise weatherstrip and the primary door seal. The illustration above shows the mispositioned weatherstrip (top) and then the correct position (bottom).
Plan-A and Plan-B Weatherstrips: During a torrential rain storm water may leak down the A-Pillar drip from the top receiver pin cup or drip from roof header onto the shifter. Refer to Corporate Bulletin Number 06-08-67-016 (Apply Sealer to Convertible Top Seam) for further information.
Condition # 2
Important:
A leak in this area may only be present when driving in rain.
The front floor carpets are wet or the carpet may be wet by the bottom of the "A" pillar near the sill plate.
Cause
The front of the dash and the floor pan seam may have a void in the sealer.
Correction
1. Shine a light from inside the vehicle and use a mirror to look up at the seam from inside the engine compartment or below the car. Clean the area with a non-oil based cleaner and reseal with urethane.
2. Run water down the front of the "A" pillar to locate the leak. Clean the area with a non-oil based cleaner and reseal with urethane.
Condition # 3
The carpet may be wet by the bottom of the "A" pillar near the sill plate.
Cause # 1
Water may be entering the "A" pillar at the windshield weatherstrip and flowing down the "A" pillar.
Correction # 1
Remove the left or right cowl screen cover and seal three locations:
^ Make sure the hole at top of the pillar is covered. Refer to the top arrow in the illustration.
^ Seal the seam at the top of the pillar with butyl. Refer to the middle arrow in the illustration.
^ Seal around the front top and back side of the upper door hinge with Kent seam sealer P/N 10200. Refer to the bottom arrow in the illustration.
Cause # 2
There may be a lack of sealer at the sill plate to the lower "A" pillar.
Correction # 2
Remove the trim at the top of the "A" pillar. Run water down the top of the "A" pillar to locate the leak.
Water will gather down at the bottom rear of the "A" pillar pool up and drain into the car at the rearmost arrow. Making sure the seam is sealed at both of the arrows will create a water path to the outside. Clean the area with a non-oil based cleaner and reseal with urethane.
2006 Solstice Only: Apply a piece of foam from the front inboard urethane inboard of the sill plate retaining holes all the way to the "B" pillar. Remove the foam gaskets from the sill plate clips.
Condition # 4
The carpet may be wet by the bottom of the "A" pillar.
Cause
The under hood wire harness on the left hand side just forward of the "A" pillar may not be routed properly causing water to enter the wire harness and flow inside the vehicle.
Correction
The picture above shows the drip loop pointing upward. The correct position should be pointing downward as show in the picture below of the illustration above. Also ensure that the grommet is fully seated.
Condition # 5
The customer may comment of water running down the "A" pillar and dripping into the car.
Cause
The two-way tape or butyl on the backside of the weatherstrip may not be sealing to the A pillar.
Correction
Clean the backside of the weatherstrip and seal the upper portion (upper three arrows) with GM weatherstrip adhesive. The bottom portion (bottom arrows) should be sealed with thin strips of butyl
Convertible Top Leaks
Prior to any repair or water testing of the convertible top:
1. Make sure the convertible top "B" pillar pins are falling into their proper position. These pins control the line up of all the seals.
2. Check if the door glass is coming in contact with the webbing of the convertible top in the upper rear corners. Refer to Corporate Bulletin Number 07-08-67-005
3. Check to see if the convertible top front center latch is bent or difficult to latch. Refer to Corporate Bulletin Number 08-08-67-002.
If the pins do not fit properly loosen the convertible top attaching bolts to the body and locator pin. Latch and secure the top and then tighten the attaching bolts and locator pin.
Work the top back and forth and retest.
Condition # 6
The customer may comment about a weep from joint # 1 (water runs down the inside of the glass) or a leak from the # 1 joint.
Cause # A
Make sure the push pin retainer is straight in the top corner of the "A" pillar of the windshield. If the pin is on a slight angle the weatherstrip will not align properly with the top weatherstrip.
Adjust the weatherstrip up or down so that the pin is straight in the "A" pillar.
Important:
A weep at the # 1 or # 2 joint may be corrected by cleaning the glass then apply a thin coat of Rain X or Aqupal on the top inside and top edge of the door glass. This will condition the weatherstrip.
Cause # B
The door glass may not be high enough in the opening and not closing the gap in joint # 1.
Correction # B
Mark the glass with a grease pencil and adjust the front of the glass 2 mm (3/16 in) upward or forward. Make sure that the stud stays in the top of the adjustment slot. This slot controls the tip in at the top of the glass.
Cause # C
Plan-A Weatherstrip Only (Plan-B does not have stuffers): The stuffer may not be in place inside the weatherstrip. There should be a bulge in the weatherstrip which will close the gap between the weatherstrip and the top.
Correction # C
If the stuffer is missing replace the weatherstrip.
Cause # D
Plan-A Weatherstrip Only (Plan-B does not have stuffers): The stuffer may not be in place inside the weatherstrip in the front of the convertible top.
Correction # D
If the stuffer is missing or out of place replace the weatherstrip.
Plan-A Weatherstrip: Replace the weatherstrip. When replacing the weatherstrip make sure the lip on the weatherstrip to top measures 7 mm (1/4 in).
Condition # 7
The customer may comment about a weep from joint # 2 (water runs down the inside of the glass) or a leak from the # 2 joint.
Cause # 1
The door glass may not be high enough in the opening and not closing the gap in joint # 2. Verify by closing door to first latch position. If glass is contacting the seal all around do not adjust.
Correction # 1
Mark the glass with a grease pencil and adjust the glass 2 mm (3/16 in) upward at the rear.
Cause # 2
Plan-A Weatherstrip (Plan-B does not have stuffers): The stuffer may be mispositioned in the weatherstrip. It should be flush to the end of the weatherstrip.
Correction # 2
Replace the weatherstrip if it is mispositioned.
Cause # 3
Plan-A Weatherstrip: The screw that retains the weatherstrip may be loose.
Correction # 3
Hand tighten the screw.
Condition # 8
The customer comment that the inside "B" pillar or the rear carpet is wet.
Cause # A
The convertible top strap may not be in the correct position.
Correction # A
Ensure the winter flap covers the rub strip slot. Rotate the canvas around the B-pillar pin to bias the winterflap over the rub strip slot.
Cause # B
The mucket weatherstrip two-way tape may not be adhered to the body.
Correction # B
Replace the mucket rub strip.
Squirt water into the weatherstrip as shown. The water should flow into the square drains in the weatherstrip and exit into the rear fender and onto the ground.
Condition # 9
The customer may comment that the rear carpet is wet behind the seat or the seat belt is wet.
Cause
Water is leaking past the tulip panel to quarter panel location.
Correction
Use strip caulk to fill in the void and smooth out the transition between the weatherstrip and the trim.
Condition # 10
The customer may comment that the carpet is wet under the two forward trunk drains.
Cause
The two drains may have a void in the sealer between the drain and the body or to much squeeze out or not enough ahsland (exposed ledge).
Correction
Clean the area with a non-oil based cleaner and reseal with urethane.
Condition # 11
The customer may comment about a waterleak at the front of the trunk.
Cause
The drain bag in the trunk may be stuck together.
Correction
2006 and early 2007 built vehicles: Clean the inside of the drain bag and install 25 mm x 25 mm x 13 mm thick (1 in x 1 in x 9/16 in thick) foam blocks to the inside of the bag. Place the foam blocks three inches apart. These foam blocks can be cut from a roll and purchased from Kent Automotive P/N P46515.
Condition # 12
Some customers may comment of water on the sides of the carpet in the rear trunk.
Cause
Water may be entering the trunk through a seam in the tonneau cover.
Correction
Clean the tonneau cover and seal with a small amount of Kent seam sealer P/N 10200.
Condition # 13
The customer may comment about a waterleak at the rear of the trunk.
Cause
