AC/Heater blower fan not working
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!!!
