Removing 4 runner antennae motor assembly

I have a 1999 Toyota 4 runner. I have changed the antennae mast with a new one but it still does not go up. The motor brings the antennae down but does not bring it back up. I suspect that the gears inside the motor are bad, as the motor was running. I can't figure out how to get the motor out. There are two wires that connect to the antennae a wiring harness that snaps off and another black wire that runs from the antennae motor through the wheel well / firewall into the car.

I got to the motor via the wheel well and disconnected the electrical harness to the antennae but I can't figure out how to get the other black cable out. This cable must run to the radio from the antennae motor. Do I need to remove the dashboard to get to the connection?

SOURCE: AFTERMARKET REPLACEMENT FOR AUTO ANTENNA

sounds simple
placement of antenna is important this will determine which wires to use
most antenas are in the trunk of vehicle with a wire clip to connect or disconnect
tools needed
test light
find your wire clip running from old antena this will be where test light will be used one side of clip is full powered the other is key powered find good ground tip the test light on first prong light stays on this is full power other will be key powered

now your looking for the simple color wires ok on the back of your sterio there is an atenna wire which is blue this will power on only when sterio is on the other wire
you use test light to find without key in take your test light and find a permannent powered full on wire hot supply then connect antenna into these 2 things

at top the reason i mentioned this is cause the old power antena you can find the right leads in the trunk area where new antenna going to be placed with the test light you might need a second person to help you testing wires you in the back and them in the front turning the key on when you need it it makes things simpler with 2 people
i hope this helped you in your quest for knowledge

ON AN ELECTRIC ANTENNA, YOU CANNOT JUST REPLACE JUST THE MAST.

SOURCE: Radio antenna

You should be able to take the plastic piece going down the inside panel from roof to dash. Usually somwhere in there or under the dash you will find a slip connection. But some go all the way to the radio.

Reverse the wires, one is hot going up and the other hot going down, the easiest way to deal with this is to just reverse them.

    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.

How do you replace radio antanna


What kind of car is it? If it is a fixed antenna you just unscrew the old one and screw on the new one. If it is an automatic antenna, you can buy either the motor or the mast. Assuming you just need to replace the mast, it comes with the plastic piece with the teeth on it. You need to remove the old broken plastic piece from the antenna motor. You might need to disassemble the antenna motor from the car to get enough of the plastic to grab onto with pliers. While you are pulling on it have someone turn on the radio to activate the antenna up motion and pull the old plastic piece completely out. With the old plastic runner out, the motor installed on the car, and the radio on, run the new plastic runner first through the doughnut screw that holds the mast to the car. Then cram the new plastic runner as far as you can into the hole that leads to the antenna motor. Then hold the very end of the mast (the tip), align the base to the opening as best you can and have someone turn off the radio to activate the down antenna motion. It goes quick so don't have your fingers where they can get pinched as the motor sucks in the plastic and the mast down into the hole. With the mast retracted, tighten the doughnut screw to that the mast won't flop out when you turn the radio back on.

Trying to replace antenna mast on 1998 toyota 4 runner sr5. New antenna does not come with bezel so how do I remove bezel from old antenna and put on new antenna? Thx


Where did you get new antenna? If no instructions talk to the Autoparts store where you bought it. There should be instructions with the antenna. What happened to old antenna? A motorized antenna? If motorized, antenna has a white nylon gear tooth at back end. If it's not motorized it may not match. The bezel usually screws into the motorized device underneath the body work. Should be way to use small wrench to turn just like a nut to remove. Hope this helps. I've changed mine several times, by going throug the carwash without turning off the radio, but
different car.

Remove broken antenna


Most electric Antennas require two people to replace. First turn key on watch and listen to antenna motor as some one turns on radio do this several times. Now remove spanner nut the antenna mast goes through then have them turn radio on again this you assist the rest of the mast out of motor assembly watching what side the teeth are on the plastic cable . Now take new mast and fully extent it and lubricate with a machine oil 3 in 1 works great. slowly lower into housing trying to get first tooth hooked or close then turn radio off this will retract the antenna into the assembly hopefully on the first try it should be all the way in. don't worry re install retainer parts raise and lower several times the overrun clutching will get it in time.

How to replace arial in 95 camry


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.

My power antenna does not go up. the mast may be missing. i can hear the motor running like it is raising the antenna then stops. do i have to buy a new assembly or can i just buy a mast?


more likely the mast drive cable is broken and needs to be replaced, very common. You will need to contact the dealer to see if they sell a mast repair kit for your car, many Japanese cars make you replace the whole antenna to fix this problem.

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
