Both tests were 0volts
The circuit it labeled ACT-E1. I wonder if that is actuation? I traced the wire blue/ yellow straight back to the amplifier.
I’m in the process of getting another ECM.

Pin 13 and Pin 25 off of the ECM goto your AC amplifier on the D connector.
13 should be a blue black wire.. 25 should be blue yellow wire
Which ac do you have the manual one ? or the automatic ? ( what does your dash controls look like? They levers or digital)
