Solved the AC part of the problem
The EHA connector and the temp sensor for the aux fan were plugged backwards (oops). The plugs are identical except for the pin size. I switched them and the AC clutch works correctly.
I hooked the meter back up to the EHA and get -0.00ma on all tests. I checked the voltage from the wiring harness plug and get 4.10v. Anyone have a clue?
