Poor reception. Changed the radio with another of the same model. Reception is still poor. Must be an antenna problem. How do I go about replacing the antenna and coax?

1. Disconnect negative side of battery.
2. Wait at least 2-minutes to de-energize the airbag system
3. Remove the glove box from the dash.
4. There will be a coax cable towards the top of the opening. Disconnect the antenna cable lead.
5. Remove the right kick trim panel. There should be no screws just clips.
6. Loosen the rubber grommet insulator from the door hinge area. This is a rubber accordian style guard for wires located between the "A" pillar and the door.
7. Pull the antenna cable out of the dash area to the hinge area.
8. Jack up the front right of the vehicle. Support with Jack Stands. Do not use only the Jack! Use the jack as a back-up in case of Jack Stand failure.
9. Remove the right front tire.
10. Remove the right front wheel housing splash shield. There should be 3-push type retainers and one 10 mm bolt below the bumper.
11. Slide the plastic cover (on the base) up on the antenna mast.
12. Use a open end wrench to unscrew the antenna mast at the base and remove the antenna mast.
13. Remove the plastic cap from the base nut on the base and remove the base nut.
14. From underneath the fender: pull down the antenna base. And pull the cable towards you - out from the door hinge area into the fender area.
Good Luck! Installation is reverse of above.
