Car Forum / Pontiac / Pontiac Firebird / March 2004Power Antenna replacement.
Hello, I bought a replacemnet power antenna at an autowreckers and we tested it there and it worked. Put it into my firebird and it doesn't work. Took it back to the wreckers and they tested it again and it worked. I hooked up the old antenna to make sure I had power to the antenna motor as the old one, the motor kept going and going. There was power. So obviously I am getting power to the antenna. Any ideas as to why the antenna I bought from the wreckers won't work? It came out of a Camaro and is virtually Identical to the one that was on the firebird. Thanks for any advice. Oh, it's an '89 Firebird if that matters. Take Care -Ron > Hello, > [quoted text clipped - 14 lines] > Take Care > -Ron Since you said "virtually identical" I'd look to see if it was getting a good ground first. Also, I think that an identical plug works differently depending on the radio/antenna combination. Depending on if they will take it back, and the price paid, you could probably buy a new aftermarket power antenna that would give you less hassle in the long run.

Yeah, they won't take it back because it works. I'll investigate the ground issue. Thanks for your advice. Take Care -Ron Here's a stupid question: Did you turn your radio on? Hey you never know... ;o) >Here's a stupid question: Did you turn your radio on? > >Hey you never know... ;o) Of Course. :) Hi Ron, You can buy a replacement antenna for a fraction of the cost of buying an antenna and motor. The antenna in your factory unit is broken but the motor is fine. The antenna is replaceable. The antenna/motor that you have has a switch that senses when the antenna is fully up or fully retracted. This switch shuts off the motor. Inside the antenna is a plastic toothed line that wraps around a wheel inside the antenna housing. When it is fully extended the mechanical resistance that it sees causes the inside of the housing to shift which opens a switch that shuts off the motor. When you turn the radio off, just the opposite happens; it retracts wrapping around the wheel until it is fully retracted. The tension in the line then shuts the antenna motor off via the switch. After many years of use the plastic line breaks, usually in the middle of being up or down. Since the portion of the line still wrapped around the wheel cannot bottom out (or top out), there's nothing to shut off the motor, thus it continues to run. Separate the two halves of the antenna motor housing by removing the c-clips around the perimeter and then drilling out the rivets. One of these rivets goes through the center of the wheel I mentioned earlier. Once the rivets are out the two halves of the housing can be separated. You can slip a flat blade screwdriver in between the halves to help pry them apart if they stick together You will then see the motor, the plastic wheel and a broken piece of the toothed line I spoke about. Remove the line and the metal sleeve that the antenna retracts into, replace the sleeve/antenna unit, making sure that you hook the end of the new antenna into the hole in the circumfrence of the wheel, and fit the two halves of the housing back together. Replace the c clips and use a nut and bolt in place of the rivets you drilled out. Plug in the antenna and confirm that it operates correctly. I hope this helps David > Hello, > [quoted text clipped - 14 lines] > Take Care > -Ron Hi David, Thank you very much for taking the time to explain this to me. I am going to give this a shot since I have nothing to lose and it makes a lot of sense. I had no idea that the antenna itself was replaceable. Take Care -Ron >Hi Ron, > [quoted text clipped - 51 lines] >> Take Care >> -Ron make sure the pos and the remote wire are getting juice from the radio. That could be the source of the problem. All aboard the Yankee express, next stop October..... Yeah, I looked further into it after I canged antennas. The antenna would retract but it won't extend. Turns out that the wire that supplies it with juice has been cut off. No doubt when the thieves ripped off my previous stereo. So I guess the installer of the new system didn't think to look into it. Thanks for the info though. Take Care Ron >make sure the pos and the remote wire are getting juice from the radio.
