You can Select Your Vehicle to check if F5DZ-18A886-A fits your vehicle.

On 1997 and later models, the antenna is a grid bonded to the rear window and cannot be replaced conventionally. To check the antenna, perform a resistance check between the cable and mast. If correct, the antenna is okay; otherwise, inspect the cable and base. Replace the cable or antenna if the resistance exceeds five ohms. Disconnect the cable from the negative battery terminal and remove the antenna for replacement. For a rear-mounted antenna, remove the trim panel, unscrew the mounting screws, and disconnect electrical connectors to remove the antenna assembly. To replace the antenna mast and drive cable, remove the retaining nut, pull out the mast, and replace the cable. Verify proper operation by activating the antenna through radio on/off cycles.

The note states that these models have an antenna grid on the left-rear quarter-glass and do not have a mechanical antenna. The grid antennas can be tested and repaired as mentioned in Section 22.

a) Be sure to install a new gasket. b) Untie the string and attach it to the new antenna cable. Slowly pull the string and antenna cable back through the body opening. Discard the string.
