Replace power antenna 2004 corvette - 2004 Chevrolet Corvette

SOURCE: 1999 corvette c

Very easily, take off the passenger side tailight (outter) two screws/torque bit. Once you have done that reach in on the inner quater panel you should be able feel the antenna....... (To remove anntenna). From the outside of the anntenna on top where the actual anntenna comes out there is a ring silver or balck. You should be able to twist (unscrew) that ring to loosen the antenna and two more on the in side of quater panel. The anntenna should drop from the inside of the quater panel. Hope this helps!!

Give these instructions a shot. Might be too generic but might be enough to get you going. Removing Original Antenna
1. Step 1 Activate the antenna switch to the up position.
   
2. Step 2 Using the wrench or needle-nose pliers, loosen and remove the original retaining nut on the base of the antenna mast.
   
3. Step 3 Gain access to the underside of the area where the antenna is located.
   
4. Step 4 Remove the bracket or brace that is below the hole and holding the antenna in place.
   
5. Step 5 Remove the mast.
   
6. Step 6 Find the motor that controls the antenna mast. Generally, power antennas will have a constant 12-volt lead and a ground lead. The ground lead will be grounded to the panel next to the motor.
   
7. Step 7 Remove the ground lead from the panel.
   
8. Step 8 Pull out the antenna coaxial cable.
   
9. Step 9 Unplug the coaxial from the extension coaxial cable.
   
10. Step 10 Remove the original antenna coaxial cable. Note the route the cable follows.
    Installing the New Power Antenna
11. Step 1 Inspect the fender area where the antenna mast will be mounted for rust.
    
12. Step 2 Clean the area before installing the new antenna.
    
13. Step 3 Plug the new antenna coaxial cable to the extension coaxial cable. (On some General Motors and Ford cars you may need an adapter to mate the 2 cables together. Car audio retail stores sell such an adapter.)
    
14. Step 4 Plug the new antenna's coaxial cable into the radio's chassis antenna jack if there is no extension coaxial cable. Tie or tape the string you put on the extension cable to the new antenna coaxial cable. This assures that the 2 cables stay together as you route them to the antenna mount in the fender.
    
15. Step 5 Connect the power lead of the antenna to the power antenna lead on the radio.
    
16. Step 6 Connect the 12-volt constant lead to the antenna to a 12-volt source or to the ignition switch.
    
17. Step 7 Direct the new antenna cable via the same route followed by the original antenna cable on up to the hole in the fender in which the mast will be mounted.
    
18. Step 8 Ground the ground lead from the motor to a clean metal surface on the metal panel near the mount.
    
19. Step 9 Insert the mast into the hole. Face the serrated side of the plastic cable on the bottom of the mast toward the motor side. The plastic cable can be inserted freely to about 12 inches and will stop.
    
20. Step 10 Turn on antenna switch to down position until the plastic cable goes down and catches into the gear mechanism of the drum housing. If the plastic cable does not gear into the mechanism, twist the cable slightly until the cable contacts into the gear mechanism while the motor is in operation.
    
21. Step 11 Stop the motor after the cable goes into the housing 12 to 25 inches.
    
22. Step 12 Secure the bracket or strap to the bottom of the antenna mast and to the metal fender.
    
23. Step 13 Replace the retainer nut to the base of the antenna mast and secure tightly.
    
24. Step 14 Replace the panel that covers the antenna mount area.

Hello, i've just checked in the procedure (25 steps in all to take it out, that's a lot!!!) for a antenna replace for you're corvette and would recomand you to go to a dealer to get the antenna replace. You may think it will be caustly but those guys know how to take it appart and won't fool around like any other mecanic that won't have the procedure. I would not recomend you to do it you're self since the procedure requires you to take most of the back end of the car appart. But if you still feel corageous, send me a message and i'll post the procedure for you.
