Disconnect the negative battery cable, ensuring that on models with the Theftlock audio system, the lockout feature is disabled before any procedure that requires battery disconnection. For the standard antenna, use a small wrench to unscrew it from the base and replace it with a new one; to remove the base, utilize snap-ring pliers to take off the base retaining nut. For the power antenna, open the trunk and take off the trim panel, then unscrew the escutcheon from the fender. Unplug the electrical connector, disconnect the ground and relay cables, drain tube, and antenna lead, and then remove the antenna and motor assembly. Installation follows the reverse order of removal.
