Hello again:
I watch my cat wander around. I know my cat doesn't think. I wonder, then, how it chooses to go one way or another. It certainly doesn't do so because it thought about it. Indeed. My cat goes through life making choices - using free will to make 'em, and does very well.
Frankly, I think my cat has a free will, in the very same sense you mean OUR free will. I don't think intelligence, or the lack thereof, has anything to do with "free will".
We're intelligent. We go through life making choices - using our free will to make 'em. I don't see a difference, except that our choices should be better than my cats. And, that isn't true.
Bottom line, I don't think that you have to think in order to have free will. And, I don't think that HAVING such a free will, overrides your genetic programming.
