It is well documented problem of the resistor & harness pigtail burnt. They need to put a recall on this too. Happens all the time on hummers happened to my brothers H2 twice in 3 years.
The fan motor is down on the pass side. follow the 2 wires that come off the motor to the heater fan resistor. If you can unplug that it. Most likely the connector will be burnt and so will the resistor. Replace connector and resistor.
