I had the same problem on another car. It was the blower motor relay... it's a possibility that it's the same problem. Wasn't too expensive for the part, and I replaced it myself.
It's called the blower motor speed control on this model as posted.
What is it with snotty people on this website? I am happy you felt you had to correct me.
