The motor for my power antenna stays on constantly. The only way to turn it off is to pull th fuse, but then I have no power locks, dome light, or horn to honk at crazy-drivin' rice buggies!!! I've got the thing in pieces right now cause I'm puttin on new struts, and I have the right wheelwell pulled out. But what the heck can I do to fix the antenna motor. The antenna is stuck "up," and it won't do down. Any help would be greatly appreciated.

i'm guessing you have it hooked into the constant in the head unit try pulling that and see what hapens

Thanks for responding. I am not sure what you mean by being hooked into the constant on the head unit.

If you have an aftermarket head unit, there is a wire, usually green, possibly with a white stripe, that is for the power antenna. Unhook the wire.

If this is a factory stock antenna, then I would have to say that the cable that is coiled in the round housing that your antenna goes into, has snapped.I would recommend buying a new one. There was someone on the TransAmGTA site that was able to purchase a repair kit from GM, but he was told that they had discontinued them, and they would become difficult to get.
My antenna did the exact same thing, and I had to disconnect it so as to shut the motor off. After tearing it apart, I found the cable to be broken.
