To remove a fixed antenna, begin by unscrewing the antenna mast from the base mount. If equipped, remove the access panel at the rear of the headliner from inside the vehicle; if there is no access panel, lower the end of the headliner. Disconnect the antenna cord from the base and unscrew the base from the roof panel. For fender-mounted antennas, raise the vehicle and secure it on jackstands, then remove the front wheel. Take out the antenna assembly from the vehicle body, removing the driver's side door pillar trim to access the antenna cable for front top-mounted antennas, or working in the fenderwell area to remove the antenna mounting bolt for fender-mounted antennas. Push the antenna mount into the fender to separate the assembly from the grommet. Remove the radio and disconnect the antenna cable, then for fender-mounted antennas, remove the glovebox and pull the cable from behind the dash. For automatic power antennas, disconnect the antenna cable from the motor. For installation, thread the antenna mast onto the base mount and tighten it securely. Feed the antenna cable behind the glovebox and into the radio, then install the radio and the glovebox. The remainder of the installation follows the reverse order of removal.
