I am ready to pull my hair out, I have spent less time on engine rebuilds than getting this freakin antenna to work.
Short story antenna stoped working so I took it out. Tore it apart and found a broke mast gear. Put it together and had a bad relay also not to mention a poped fuse. OK now all is great and antenna is going up and down NO! The freaken thing goes up when the stereo is off and down when it is off.
I tore it back apart and there is a small dial that that operates the up down gears so I resinked the dial same issue though. I tried rebooting the battery, I have tried everything possible. I even checked wirring for reverse of polarity some how.
ANYONE GOT ANY THOUGHTS?
What 383vette said. DC motors typically run one direction with one
polarity, reverse the wires and they will run the other way. Could you
have switched the wires somewhere?
I don’t think you could have messed up anything external to the antenna. I beleive it is on a plug. You can check it out manually to see if it works OK as a standalone item.
Ground is the case. The orange wire is the power feed of 12 volts always on. The white wire triggers the antenna up or down. With no voltage to the white wire it should be down. If 12 volts is applied to the white wire it should go up. If it does not work this way then you will have to open it up again.
Did you work on the electrical at all inside?
Sounds like the motor or limit switches are working in reverse. Hard to say how that could happen, have not had one apart in several years.
Power antennas are a beatdown, I feel your pain. Years ago I had an 80 and an 82 and it was constant issues until I replace them both. I have a 94 coupe that I bought about a month ago, the antenna works when it wants to. I am not messing with it, I will buy a new one or some type of fixed mast.
You guys are not going to believe this. When trying to figure out why the motor wasn't working I took the metal cover off the electric motor. when I put it back on I thought I put it the same way. Well after all else failed in the process of elemination the only thing I didn't try was turning the motor cover 180* THAT DID IT! The cover also holds the magnets for the motor and the only thing I could think was they are defrent polarity or somthing. There was a small metal piece on the wall of the inside of the cover maybe that had somthing to do with it
I do know how to rebuild one of these suckers with my eyes closed

Thanks!
Just want to say 'thanks very much!' to C4vettrn. I was doing a power antenna repair on my '00 Toyota 4Runner and ran into this very same problem! ...was driving me nuts trying to figure out why the antenna was operating backwards. Sure enough, I had at one point removed the motor cover during the repair and inadvertently put it back on backwards.
Anyway, thanks again! I greatly appreciate your post, and had not thought to check this until seeing it. Was really scratching my head until seeing this thread.
