I recently replaced the blower motor and the electronic controls. The blower motor only blows at one speed (med.) What other causes could there be or what else should I consider?I am considering Sword unit or blower motor resistor. Which would you think is more likely? I'm told that there is also a Aux. Fan resistor. What is this and does it have anything to do with my problem?

The blower motor resister would be the most likely there.
