You guys were right, my furnace does have a control module/circuit board with a light that blinks. Right now it's blinking dim-bright-dim-bright which means that it's fine.

I also see the wires for the high speed (cool) and low speed (heat) blower circuits. And I found the instruction manual that details out the steps that Rick-I listed in his post. I'm going to monitor the system tonight so I can tell when it kicks on and off to see if it's working properly or not.

Thanks for all of the help.
