Measure you fan motor. Find out the shaft length and diameter and the spacing and size of the mounting bolts. Then along with the motor length and diameter go to your local NAPA dealer. They have a book on blower motors. See if they can find you a 2 speed motor that will work. Then change the switch to a two position one.
I try not to use the ceramic resistor switches as they can build up a lot of heat.
