Removal Procedure
Notice: DO NOT close the lift window panel with the struts attached unless
the window is installed and the window adhesive fully cured. The window adds
strength and rigidity to the lift window panel. Attempting to close the lift
window panel, with the struts installed, without a window or with
the window adhesive not fully cured, could cause the panel to crack.
Important: Before cutting out a stationary window, apply a double layer of masking
tape around the perimeter of the painted surfaces and inner trim of the window.
- Install a protective cover inside the vehicle.
- Remove the lower garnish molding and the rear compartment front
side trim panel for access to the inside of the window. Refer to
Rear Compartment Side Trim Panel Replacement
.
- Disconnect the rear window
defogger connectors at the window.
Caution: When working with any type of glass or sheet metal with exposed or rough
edges, wear approved safety glasses and gloves in order to reduce
the chance of personal injury.
Important: Keep the cutting edge of the tool against the rear window. This will
allow the urethane adhesive to be separated from the rear window. Leave a
base of urethane on the pinchweld flange. The only suitable lubrication
is clear water.
- Use the J 24402-A
or J 39032
in order to cut the rear
window from the pinchweld flange. Do this from inside the vehicle in order
to protect the outer paint surface.
- With the aid of an assistant,
use the suction cups in order to lift the rear window from the opening.
Installation Procedure
- Verify all primers and urethane adhesive are within expiration
dates.
Caution: When replacing stationary windows, use Urethane Adhesive Kit GM P/N 12346392
(Canadian P/N 10952983), or a urethane adhesive system meeting GM Specification
GM3651G, to maintain original installation integrity. Failure to use the urethane
adhesive kit will result in poor retention of the window which may allow unrestrained
occupants to be ejected from the vehicle resulting in personal injury.
- Inspect the following components for the causes of a broken rear window:
• | The flange of the rear window opening |
• | The rear window reveal molding |
- Inspect for any of the following problems in order to help prevent
future breakage of the rear window:
• | Hardened spot weld sealer |
• | Any other obstruction or irregularity in the pinchweld flange |
Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs
or replacements are necessary, refinish the pinchweld flange in order to present
a clean primer only surface. If paint repairs are required, mask the
flange bonding area prior to the application of the color coat in order
to provide a clean primer only surface. Materials such as BASF DE17®,
DuPont 2610®, Sherwin-Williams PSE 4600 and NP70® and
Martin-Semour 5120 and 5130® products are approved for this
application.
- After repairing the opening as indicated, inspect the condition of the
rear window opening and the urethane adhesive bead in order to determine which
installation method you will use.
- Refer to
Short Method Description
or
Extended Method Description
for the guidelines.
- Clean around the edge of the inside surface of the rear window
with a 50/50 mixture of isopropyl alcohol and water by volume on a
dampened lint free cloth.
- After repairing the opening as indicated, shake the pinchweld
primer (black #3) for at least 1 minute.
- Use a new dauber to apply
the pinchweld primer (black #3) to the surface of the bonding area
on the body only.
- Allow the primer to dry for approximately 10 minutes. Ensure
that all nicks and scratches are covered.
- Starting with the lower
molded corners of the reveal molding, install the reveal molding to the window.
- With the aid of an assistant,
dry fit the rear window in the opening in order to determine the correct way
to position the rear window in the opening.
- Use masking tape in order to mark the location of the rear window
in the opening.
- Slit the masking tape at the top edge of the rear window.
- With the aid of an assistant,
remove the rear window.
- Place the rear window inside up on a clean, protected surface.
- If the original rear window is being reused, remove all but approximately
2 mm (3/64 in) of the existing urethane adhesive from the rear
window surface, using a utility knife or razor blade scraper.
Important: Do not remove all traces of the adhesive. Remove all mounds or loose
pieces of urethane adhesive .
- If the extended method is being used remove all but approximately 2
mm (3/64 in) of the existing bead of adhesive from the pinchweld
flange.
- Clean around the edge of the inside surface of the rear window
with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened
lint free cloth.
Important: Do not apply the (black #3) primer to the existing bead of the
urethane adhesive. Apply the primer only to nicks, scratches or the primed
surfaces.
- Shake the pinchweld primer (black #3) for at least 1 minute.
- Use a new dauber to apply the primer to the surface of the pinchweld
flange.
- Allow the pinchweld primer to dry for approximately 10 minutes.
Important: Use care when applying the prep (clear #1) to rear window. This
primer dries almost instantly and may stain the viewing area of the rear
window if not applied evenly.
- If the extended method is being performed, shake the rear window primer
(black #2) for at least 1 minute.
- Use a new dauber, in order
to apply the rear window primer (black #2) to the areas of the rear
window (1) to which prep (clear #1) was applied.
- Allow the primer to dry for approximately 10 minutes.
- If using the short method,
cut the tip of the applicator nozzle in order to provide a bead of 6.0 mm
(1/4 in).
- If using the extended method, cut the applicator nozzle in order
to provide a bead 10.5 mm (0.14 in) wide and 10.5 mm
(0.14 in) high.
- Use a cartridge-type caulking
gun, apply a smooth continuous bead of new urethane adhesive around the edge
of the rear window where the primer was applied.
- When using the short method, apply the urethane adhesive to the
existing bead of urethane adhesive on the body.
- When using the extended
method, use the edge of the rear window or the inside edge of the reveal
molding as a guide for the nozzle in order to apply the urethane adhesive
to the inner surface of the rear window.
- With the aid of an assistant,
install the rear window into the opening.
- Align the tape on the rear window and on the body.
- Press the rear window firmly into place in order to wet-out and
seat the urethane adhesive.
- Tape the rear window in places to the body in order to minimize
movement until the urethane adhesive cures.
- Clean any excess urethane
adhesive from the body.
Important: Do not direct a hard stream of high pressure water at the fresh urethane
adhesive.
- Use a soft spray of warm water in order to immediately water test the
rear window.
- Inspect the rear window for leaks.
- If any leaks are found, use a plastic paddle in order to apply
extra urethane at the leak point.
- Retest the rear window for leaks.
Caution: Insufficient curing of urethane adhesive may allow unrestrained occupants
to be ejected from the vehicle resulting in personal injury.
• | For the moisture-curing type of urethane adhesive, allow a minimum
of 6 hours at 21°C (70°F) or greater and with at least 30 percent
relative humidity. Allow at least 24 hours for the complete curing
of the urethane adhesive. |
• | For the chemical-curing type of urethane adhesive, allow a minimum
of 1 hour . |
Do NOT physically disturb the repair area until after these minimum
times have elapsed.
- The following conditions must be maintained to properly cure the urethane.
39.1. | Partially lower a door window in order to prevent pressure buildups
when closing doors before the urethane adhesive cures. |
39.2. | Do not drive the vehicle until the urethane adhesive is cured.
Refer to the above curing times. |
39.3. | Do not use compressed air in order to dry the urethane adhesive. |
- Connect the rear window defogger connections.
Caution: If broken glass falls into the defroster outlets, it can be blown into
the passenger compartment and cause personal injury.
- Remove the protective coverings and tape from the vehicle and the headliner
