  Q: How to remove and replace the antenna mast and cable assembly on Chevrolet Trailblazer and Buick Rainier?

  A: To remove the antenna mast, use a small open-end wrench to unscrew it, taking care to avoid scratching the body by surrounding the base with masking tape. If the antenna base/cable assembly needs to be replaced, remove the glove compartment and detach the lower rear portion of the inner fender liner. Disconnect the antenna mast cable from the radio cable at the connector under the far right end of the instrument panel and attach a fish wire to the cable. Pass the cable and grommet through the hole in the cowl into the fender opening from inside the inner fender liner. Under the hood, remove the antenna mast base mounting screws and pull out the base and its cable. For installation, attach the new cable to the fish wire and carefully pull it back into the body, following the original cable's routing. If the extension cable needs to be replaced, remove the glove compartment and the passenger's airbag module. Release the cable from the clips along the top of the instrument panel and disconnect it from the radio and antenna base cable. Finally, reverse the removal procedure for installation.
