'99 Rodeo fan stopped working

Hi all,
The fan in my wife's Rodeo stopped working today. I looked for the fuse in the fuse panel but there was nothing for the fan. How do I go about troubleshooting this? It's getting cold and she needs her heat. :)
Thanks

Assuming this is the HVAC fan, check the resistor pack in the heater plenum under dash on the pass side. It's the device that regulates the fan speeds. They often burn out.

What does this look like. What is the heater plenum? What does that look like? I am not familiar with the Rodeo.

Trace the heater control wiring to the 'black box' under the dash. It's all in there.
