Power Antenna Woes

[Coan]

The power antenna motor in my '97 quit working last fall. I recently picked up a '95 parts car with a working power antenna. Last night I pulled out the working antenna/motor assembly from the parts car, and without removing the old one I plugged the new one into my '97 and laid it on the trunk to test. It does not work either (in my '97). Works just fine in the '95 though.

Clearly there must be an issue with getting power/signal to the antenna. I checked the motor connector with a multimeter and it seems that one of the 3 pins is getting 12v when the radio is on. Has anybody else encountered this issue before? Could the problem be something inside the stock radio not transmitting the power? My stereo system is 100% stock, complete with buzzy, blown speakers.

I searched, but every thread I found ends with the motor being the problem. Can't seem to find anyone with this issue.

Of course, now that I created a thread I just found this post

The latter gets +12V to raise the antenna, or open-circuit to let it retract.

I already checked all the fuses under the hood and none are blown. Now that I know each pins function, I guess I better recheck each pin on the motor connector to see which one is not doing it's job.

Do you have the stock radio in the car?

[Blacky]

Yes. (see first post).

Have you tried swapping the radio from the parts car?

I have not because it's in very poor shape. I do have a 2003 WRX 6 disc changer sitting on the shelf though, it may be time to finally order that wiring harness that I need for it.
