High Mounted Stoplamp Replacement (Envoy)

REMOVAL PROCEDURE




1. Remove the roof rear upper garnish molding.

IMPORTANT: Before replacing the high mount stoplamp, ensure that the power and ground have been verified. Refer to Stoplamps Inoperative (Domestic) or Stoplamps Inoperative (Export).

2. Disconnect the high mount stoplamp electrical connector.
3. Using a heat gun, apply heat to the tape seal until the seal becomes soft and pliable.

IMPORTANT: Ensure that care is taken when making this cut. The spoiler and/or window frame surface may be damaged and lead to premature corrosion.




4. With a flat-bladed tool, cut the tape that seals the spoiler to the liftgate window. This cut will be made along the top, left and right edges.
5. From the top edge, pull the spoiler back to release if from the liftgate window clips. The locating clips on the spoiler may break. These are for assembly locating purposes only. The spoiler will still snap into place during assembly.
6. Place spoiler on the roof of the vehicle.
7. Remove the liftgate window from the vehicle.
8. Remove all traces of the adhesive from the window using a general purpose adhesive remover or an adhesive remover disc (3M part number 7501 or 7502 or equivalent) attached to a drill. A 50 - 75 mm (2 - 3 in) square rubber or felt block may also be used to aid in the removal of the old adhesive.
9. Clean the affected area with a suitable grease remover and wipe clean with isopropyl alcohol.
