Looking for the same thing. I saw something on here a while ago that had the parts you needed to get from Radio Shack. Something about a diode or resistor, or something failing on the board behind the switch. Finding which one is broke In your case probably just the lowest setting one and replacing it. I've got an easy night at work so far. If I find anything I'll link it up.

Yup, Blower Motor Resistor.

I've done them in many trucks (including mine). Pretty easy, and pretty cheap.

Good Luck.
