03 e53 AC problems

[jimdanforth]

Sunroof was left open in rain storm. AC was working but honestly cant say how recently as I don't drive the vehicle, my wife does and she rarely uses it, but we are approaching 100 degrees here and I need it now.
Tests so far:
Temp control all seems normal, light comes on for AC button.
Compressor clutch does not engage.
Auxillary fan does no activate.
INPA will not connect to module, but on general info screen shows AC is not on and clutch not activated.

No voltage at compressor clutch
injecting 12v does activate clutch and cool.
Pulling the pressure sensor on the AC high line does not activate the Auxiliary fan.
Reseated plugs on thermostat inside cabin

Anything else to try before replacing the thermostat control?
Salvage yard is 3 hr round trip and since this has the rotary style controls, I'm very limited on what years of the X5 work, and the lots only shows 1. No idea if the part is even there.
