How is the antenna module accessed and How to replace the rear and front antenna cables and Antenna on Cadillac CTS?

The antenna is an integral component of the rear window and cannot be serviced separately. To access the antenna module, remove the C-pillar trim and pull down the rear of the headliner, then disconnect the electrical connectors and remove the module mounting fastener. Installation is the reverse of removal. The antenna cable consists of two cables: front and rear. The rear cable is routed down the right C-pillar, between the body and the back seat, along the rocker, under the door sill panels and carpeting, ending at the right kick panel where it connects to the front cable. The front cable is routed up behind the right kick panel, turns left across the glove box area, and connects to the backside of the radio. These cables are part of the wiring harness under the carpeting, and if replacement is necessary, disconnect it at both ends and leave it in place while installing a new cable. To access the rear antenna cable, remove the back seat cushion, right C-pillar, front and rear door sills, front passenger seat, carpeting, and right kick panel. Disconnect the rear antenna cable from the antenna module and the front antenna cable, then install the new cable. For the front antenna cable, remove the right kick panel, glove box, and radio. Disconnect the front antenna cable from the radio and the rear antenna cable, then install the new cable.
