Sounds like the blower motor resistor assembly, located lower right side of dash near the blower motor

Your answer was right on the mark!
I called the Chevy Dealear for a replacement resistor assembly and was told they also have trouble with the connector, burnt and loose connection. I cleaned it up and the fan works fine. Sounds like they have a defective connector, but they will sell you a new one for $44.27.
