No Most power antenna work the same. it takes two people to change them. watch and listen as radio is turn on then off do this several times then remove retainer nut turn radio on and assist removal of remaining mast watch where the teeth are located in motor assembly. fully extend new antenna mast lube with machine oil 3 and 1 works great then slowly feed new mast into motor assembly then turn radio off as you guide new mast down install retainer parts work antenna up and down overrun clutch will make the final adjustment.

The antenna mast is extended and retracted with a flexible strip of plastic cable with teeth. The antenna motor turns a gear which drives the cable in (mast down) or out (mast up). These cables do break. You can buy a whole new power antenna assembly or just the plastic cable. Replacing the cable isn't hard, just tricky-- getting the cable to coil up properly inside the antenna assembly can be a pain. You probably can grab the antenna and extend it manually, but you may not be able to push it back in.

Typically there are two ways: easy and major surgery. The easy way is available, depending on exactly how the old mast is broken....Car off, radio off, unscrew the external pieces of the antenna at the mount, right where it exits the vehicle...Have assistant turn on radio and activate the antenna. It should spit the whole mast and inner piece. The new one goes in, BUT BE ready to carefully and without kinks, feed the new mast assembly.
If this method does not work, you have to extract the entire motor assembly and open it up. Sometimes easier to replace the assembly.

Hope this helps you ??

This is normally due to a broken antenna mast inside the motor, the mast /cable assembly should be replaced, the antenna motor has to be removed from the car and disassembled to remove the broken piece of the old cable, once that is accomplished the antenna motor is reinstalled and the new cable assembly is fed into the motor by turning the radio on until the motor stops and then turning the radio off while feeding the new mast in.

mast
Mast, Power NOTE: A power antenna mast which is bent or broken can be replaced without replacing the motor and tube assembly.
Removal

1. Remove radio antenna nut (18865) and radio antenna stanchion (18919) .
   
   
   
   

1. Loosen retaining nut inside tube using 14 mm (9/16 inch) socket, and slide nut part-way up mast.

1. Raise antenna to run plastic drive wire at bottom of mast out of motor. Note direction of teeth on plastic drive wire.

1. Saw off damaged portion of antenna mast. Remove burrs from mast and slide nut and contact tube off stationary tube.

Installation

1. With the teeth on the plastic drive wire facing toward motor on antenna, push end of plastic drive wire of replacement mast assembly down into tube. Push it around curve at bottom of tube until end enters drive mechanism.

1. Run motor down while pushing on plastic drive wire until about 305 mm (12 inch) of wire has been drawn into the tube. Stop motor and insert bottom of antenna mast into tube. Lower mast.

1. Slide contact tube and radio antenna nut down antenna mast. Tighten nut to 0.45 Nm (4 lb-in).
   
   
2. Raise and lower antenna several times to ensure proper operation.

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.
    

my antenna just stopped working in my MR2 2003 Spider. The motor still runs but the antenna will not go up and down. It made a weird noise and I had to pull the top of the antenna up to stop the motor from sounding loud.

Should I replace this or can you disconnect it and push the antenna up and down?

Thanks

Disconnect the negative battery terminal. Note the way the motor is oriented as installation is the exact order of removal. The motor is held in place on its mounting bracket by two screws. Use either a socket wrench with an extension or a screwdriver with a ratchet to remove the bolts. Note that one of the bolts has a ground/power wire for the antenna.

2. With these two bolts loosened, you will be able to pull the antenna down toward you enough to loosen the antenna gain and positive power wires located at the top of the unit. With all these wires removed, the entire assembly can be pulled down for access while leaving the wire that lead inside the motor housing intact.
3. With the unit now in your hand, roll up the black rubber sleeve that protects the unit from moisture, dirt, etc. There are approximately four Phillips head screws that hold the cover on the motor housing. Remove these screws. Also, remove the center nut that holds the antenna flywheel in place. With the cover off, you will see the flywheel and the main gear that raises and lowers the nylon antenna ribbon. You will also more than likely find bits or long sections of your OLD ribbon. Remove them.
4. Now is the time to lubricate the main gear and flywheel with either Vaseline or white lithium grease to ensure years of trouble-free operation with your new ribbon.
5. Replace the flywheel (noting its direction) and screw the cover back into place. Re-install the antenna, connect all the wiring and hook your battery back up. Turn on the ignition and radio and listen to see if the motor runs. If it does, you are ready to install your new mast.
Just follow the directions that came with it and you should be in great shape.
