    the fan resistor is either good or bad.
    the switch may be the issue but you would need a voltmeter to confirm power.
    the most likely issue is the blower motor. common failure.

    Thank you for responding Roy. I appretiate your time. It started working again, a few days ago and I've had no problems since. I am affraid it's going to turn out to be a loose ground or a short to ground somewhere. Either way it's not going to fun finding it.
