That can very well be the blower module, (resistor) but you may want to check the relay as well. There is a fuse link that powers the blower module, so check for power at the red wire to make sure it's not blown. Here are the locations of them along with a wiring diagram.

Super, I agree, I did not find a blower relay in the area so I'm assuming that it is not there with blower control module. The schematics are great explains a lot, looks like if there is power to the module it must be the module.With $160 for a blower control module, it's good to check with the experts first. Thanks! Well worth the diagnosis.
