Hi djdomin and nowitzke,
I had a similar problem with my daughters 2001 Pontiac Grand Prix.
There is a Blower Motor Resistor that is connected with the Blower Motor. This is where the power for the various fan speed positions comes from.
My daughter's car only had power to the blower in the highest position and sometimes it wouldn't work at all.
After the resistor was replaced, the blower worked as advertised in all positions.
I hope this info is of use to you both. Good luck.
