Question about 1985 Mazda RX-7

Open Question

Power antenna I replace the OEM power antenna on my 1985 RX7. I can make the mast go up and down by "hot wiring" it. But when I try to make the correct, final connection, nothing happens. This car has a power antenna relay, and I was wondering if that is bad, will the antenna work?

How to replace a1985 rx7 antenna


you have to remove the tail light assemble to get the antenna and motor out. Remove the 10mm nuts and unplug the harness from the lamp assembly. Carefully remove the assembly, to save the seal. It has to slide to the outside a little to clear the two outer studs.
Remove the back and right side quarter panels. loosen two 10mm nuts for the antenna, remove the retaining ring fender; remove 10mm nuts; unplug power and antenna leads; move bottom of assembly forward to clear fender; remove through tail light hole.

Power antenna broke and I need to replace it. How


Buy replacement antenna mast. Remove old one by unscrewing the retaining cap nut. Turn on the radio & let the antenna cable run all the way up while you pull on it to remove it.
Install the new antenna mast by turning the radio 'off' so the spool inside goes back to its beginning while you feed the cable of the new antenna down into the antenna mast hole.
Once the cable is all the way down, reinstall the retaining nut/cap and turn on the radio to allow the spool to run the antenna 'UP.'... cycle the radio ON and then OFF several times allowing the antenna to move all the way up and all the way down.
That's it!

Antenna mast broken


    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.

Replace antenna on 2003 mr2 spyder


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
