WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Savana Special, 2003 GMC Savana Camper Special, 2003 GMC Savana, 2003 Chevrolet RV Cutaway, and 2003 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
- Clean the inside of the rear window with an alcohol wipe.
- Dry the glass thoroughly using a lint free cloth.
Important:
- The adhesion promoter must be used to assure adequate bonding of the coupling.
- Mask off or protect areas before applying the adhesion promoter.
- Apply Glass Adhesion Promoter GM P/N 12378555 (Canadian P/N 88901239) to the rear window in the area where you will install the antenna coupling. Follow the Glass Adhesion Promoter instructions on the product label.
Important:
- The RF connections for the inner antenna coupling should run parallel to the defogger gridline.
- Align the inner and the outer antenna couplings.
- Do not touch the adhesive backing on the antenna coupling.
- Remove the protective film from the adhesive backing on the inner antenna coupling (2).
- Align the inner antenna coupling (2) to the existing exterior coupling.
- Connect the coaxial cable to the inner coupling (1).
- Press firmly on all 4 corners and on the center of the antenna inner coupling (2) in order to ensure proper adhesion to the rear window (4). Hold pressure on the inner coupling (2) for 10-30 seconds.
- Ensure that no gaps occur between the couplings (5,2) and the rear window (4).
- Keep the vehicle dry. Allow 6 to 8 hours, at 15°C (60°F), for the adhesive to cure after installation.
