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?

Do you
have the same problem?

The blower motor resister would be the most likely there.
