Remove the switch and check for power at the HIGH terminal (believe it's terminal "C")of the switch, with the ignition switch on and the blower switch on high. There should be 12 volts there. If there isn't voltage there replace the blower switch. (Can get then at junk yards pretty cheap).
Let me know if you need more advice on this matter.
