Removal Procedure

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

Important:

Use adhesion promoter to ensure adequate bonding of the coupling.
To obtain maximum adhesion between the new mobile antenna couplings and the glass surface, the couplings and the glass must be kept dry and above 15°C (60°F) during installation. Allow 6 to 8 hours, at 15°C (60°F), for the adhesive to cure after installation. Otherwise, the new couplings may not adhere.

Do not attempt to reinstall the original cellular antenna exterior coupling or inner coupling using any type of glue, adhesive tapes, etc. Doing so may eliminate the cellular signal transfer through the glass and reduce the maximum performance of the system, including the air bag deployment notification.

Install the inner coupling first if both the inner and the outer coupling are to be replaced. Refer to COUPLING REPLACEMENT - ANTENNA INNER .
NOTE: If you use a razor blade or other sharp tool in order to remove the adhesives or foreign objects from the inside of the rear window, use the blade carefully. Damage to the grid lines may result.
Use a small wide-bladed plastic tool to cut the double back tape material while lifting up on the outer antenna coupling (5).
