Condition
Some customers may comment that the CHMSL applique is loose on the liftgate glass.
Cause
A poor bonding of the double-sided adhesive tape between the CHMSL applique and the liftgate glass may cause this condition.
Correction
Re-tape the CHSML applique to the liftgate glass using the following service procedure:
- Open the liftgate glass.
- Remove the screws that retain the applique to the liftgate glass.
Notice: Do not damage the applique or the liftgate glass when removing the applique from the liftgate glass.
- With a flat-bladed tool, carefully remove the applique from the liftgate glass.
- Remove the CHMSL harness grommet from the roof panel.
- Disconnect the CHMSL harness connector.
- Place a clean fender cover on a suitable working surface and place the applique on the fender cover.
- Remove the old adhesive from the underside of the applique. (For Saab Only - Remove the two screws from the CHMSL and remove the CHMSL from the applique. Remove all the ribs from the back side of the applique as seen in
illustration above. Clean the applique and the CHMSL with Isopropyl Alcohol (rubbing alcohol), 3M® P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette. Apply double-sided adhesive tape, 3M® P/N 06397 or equivalent to
the CHMSL lens as seen in the illustration below and install the two screws and tighten).
Tighten
Tighten the two screws to 2.5 N·m (22 lb in).
- Clean the application area of the CHMSL applique with Isopropyl Alcohol (rubbing alcohol), 3M® P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette.
- Apply double-sided adhesive tape, 3M® P/N 06397 or equivalent, to the underside of the CHMSL applique.
- Remove the old adhesive from the liftgate glass.
Important:
• | The installation area of the liftgate glass must be clean and dry. Any airborne dust, oils, etc., may contaminate the glass or the applique adhesive, and reduce the bond of the tape. |
• | DO NOT use commercial glass or surface cleaners. These may contain petroleum. |
• | The glass surface temperature should be no lower than 21°C (70°F) and not exceed 38°C (100°F). |
- Clean the application area of the liftgate glass with Isopropyl Alcohol (rubbing alcohol), 3M® P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette.
- Apply adhesive promoter, P/N 12378555 (in Canada, use P/N 88901239), to the liftgate glass surface, completely wetting the applique application area.
Important:
• | Use a clean low lint towel or towelette and wipe the glass, only removing the excess adhesive promoter from the liftgate glass. |
• | Do not wipe the glass dry. |
• | Allow the liftgate glass to air dry completely. |
• | The applique must be installed within 30 minutes following the use of the promoter. |
- Allow the adhesive promoter to remain on the glass surface for a minimum of 10 seconds.
- Attach the CHMSL wire to the connector and install the grommet.
- Slide the liftgate glass on the hinge pins to the left in order to allow clearance for the locating hooks.
- Remove the protective liner from the tape on the applique.
- Attach the locating hooks on the applique to the hinge pins.
- Apply the applique to the liftgate glass.
- With the heel of your hand, and starting from center of the applique and working outward towards each outer edge, apply even and consistent pressure insuring complete contact of the adhesive strip to the glass.
- Install the screws that retain the applique to the liftgate glass.
Tighten
Tighten the screws to 5 N·m (44 lb in).
Important: The vehicle must be kept dry and at 21°C (70°F) to 43°C (110°F) for no less than 4 hours to ensure proper adhesive cure time.
- Clean the liftgate glass and applique area.
