Next I figured I would plug my Peake reader just for the hell of it and got 7d and 8d. 8d is Ebox Fan! 7d is not on the table which is weird. If I had my multimeter I would check for voltage but can't find it.
I took someone else's suggestion of removing the A/C pressure connector? Then run AC on Max, still no dice...
I think it's pretty safe to say the Ebox fan is bad, but I will verify with the multimeter to make sure it's getting juice.
I still did not figure out why INPA isn't reporting that the fan has a fault...

I think you may be confusing the Aux. fan with the E-Box fan. I'm pretty sure they are different things.
The Aux. fan is (of course) the large diameter electric fan behind the grill (in front of the radiator) - the fan you are trying to diagnose.
The E-Box fan is a small cooling fan inside the E-box (electronics box) just below the windscreen . It keeps the DME and the other electrics inside the E-Box cool. Item 2 in the image below: -
The two fans have no connection to each other .
