Hank, Since the 4th speed is working ok, that tells you the switch is working and the voltage feed thru the Circuit breaker is ok, If all the connections are good then the only thing left is the resistance wire for the third speed. I haven 't removed one, but normally the it's mounted on the blower box under the passenger side with two screws.
