Removal Procedure

WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
  • The adhesion promoter must be used to assure adequate bonding of the coupling.
  • To obtain maximum adhesion between the new cellular antenna couplings and the glass surface, the cellular antenna couplings and the glass must be kept dry and above 15°C (60°F) during the installation, and for 24 hours immediately following the installation. Otherwise the new couplings may not remain on the glass.
  • Do not attempt to reinstall the original couplings 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.
  1. Install the inner coupling first, if both the inner and outer couplings are to be replaced. Refer to COUPLING REPLACEMENT - ANTENNA INNER   . 
  2. Use a thin, wide-bladed plastic tool to cut the double back tape material, while lifting up on the outer antenna coupling.
