Most likely- a stuck blower relay (this is in the fuse box under the hood, try pulling it, or tap on it, and see if the blower stops). If it's this the blower would be running on the highest speed.

Less likely but possible- a problem in the BCM. If it's in here the blower would run on a lower speed but you'd probably be able to control the speed and turn it off.

interesting problem

may be some ghost reside in the car, who need blower to work while you are away.
