AC/Heater blower fan not working

[hernamf]

I have a 2007 Armada with the split temp controls for driver and passenger. For some reason, my blower motor quit working. I have read the various threads and still not exactly sure how to proceed. The rear blower works fine. When I turn the knob on the dash, I do here a click in the area of the blower motor in the passenger foot area (under the glove box). Here is what I have done so far...

1. Checked the two 20A blower fuses under the hood and all fuses in the dash. They are ok.
2. I removed the blower motor and tested it with a battery. It spins.
3. I used a multimeter to check the voltage on the connector for the blower motor....NO VOLTAGE.

I assume I have a bad Variable Blower Control Module (27151-ZM70A). Is this the same as the resistor?...or is that a separate part?

Is there a blower switch or anything else that could fail?

Thank you in advance for your help!!!

The blower control module and the resistor serve the same purpose. (Early models had the resistor, later have the module).
It sounds like the module is bad.

You're right. The module went bad. I purchased a replacement from my local dealer ($55) and that did the trick. Thanks!
