You might want to check the resistor continuity for fan speeds 1 and 2
(connect pin, not electric source) and other end to ground.  If there is
none, it will likely be the thermal fuse that allows for speeds 1 and 2.  I
replaced mine from Radio Shack with an equivalent fuse for about 50 cents
and about 30 minutes of my time.  It has now been 14 months and going
strong.
