2007 Tahoe Rear HVAC not blowing Sign In

Hello, My 2007 Tahoe, LTZ is having issues with the rear HVAC blowing from the overhead vents. The front all works fine, both driver and passenger zones. Whe nI switch/engage the rear blower fan..........nothing is blowing. Is this the fan or the Resistor for the rear? Is this something I can change? Where is it located, back passenger wall?

Be sure to check for power before condemning.

You want to test for power and ground arriving at the motor before condemning the resister/module also.
