Hi,
If you are unable to turn it off, my first suspect is the blower motor high relay. It is located behind the instrument panel compartment. See pic 1 below.
The remaining pics are the directions for the removal and installation of the relay. I would start by removing it and testing it. Here is a link that explains how to test a relay:

Let me know what you find or if you have other questions.
Take care,
Joe
