I found my answer on the internet, using Yahoo search. Here is the solution to "my fan would not blow heat or cooling" Blower motor resistor is stuck. Turn the switch on with the a/c on high, with the engine off, then hit the blower motor resistor. The fan should start working. Resistor is located on the fire wall behind the right valve cover. Also behind the heater hose. It's about the size of a deck of cards. I put a screw driver against it and then tapped the screwdriver and WALLLA the fan started.
I hope this helps someone down the line somewhere!
