It will eventually run at low speed if you let it sit and idle.  If
low speed isn't working it will eventually run at high speed.

To check everything except the thermoswitch, go to the thermoswitch
connector and jumper amongst the three wires with a paper clip until
you get two different fan speeds.  There are hot, low speed, high
speed.  Have no fear for your fingers as the high speed circuit is
actually powered by a relay.
