Power Antenna Continues To Run

Since the other day, my power antenna continues to run whether I have the power to the stereo on or off. I hadn't played the stereo the last few times I drove the car. I was surprised to hear the motor running while the stereo was off. It really surprised me that it continued to run while the power is off. I pulled the fuse, which I learned also serves the power locks and interior lighting. I did a little research and learned that if the cable inside the antenna breaks, the motor will continue to run. Is that true even if the power to the stereo is off? Or, could it be a short in a wire somewhere?

Thanks for any information!!
 
Yeah I had a tta with a broken cable and motor kept running. I put in a new cable from gm but for an even better fix look at the sticky thread on turbobuick.com by 2quick6 "aka" Rob. He did a great write up on fixing this with a wire cable so it will never break again.
 
I had this failure a few years back.

Without the factory nylon ribbon or cable, the mast doesn't move. Until it senses the mast reaching the ends of it's travel (in or out) the motor will run until your battery is dead.

I posted a lot of details on the replacement of mine (I sent it out to be rebuilt with a steel cable), and the multiple side jobs it lead to (by my choosing), on TGO, if you care to have a look. You'll see photos of some of the steps to get there, replace the unit, wiring connections, etc.
