AC clutch circuits are like they were in the good old days...
Every thing has to report to the PCM for any reason even reasons that are not AC related the PCM will kill loads and the AC is a big load so it will go for the big unneeded first...
A example would be if the coolant temps were above normal it would shut down the AC in a effort to bring the temps down..
Another would be full throttle are even a load such as Turning the steering wheel to full lock in a parking lot situation... When the PCM sees a high load applied to provide full power are to control idle it may shut the AC down...
It would be rare to see battery voltage at the AC clutch threw all the wiring and switches then add in a well worn clutch a 1 to 1 1/2 voltage drop is the norm...
Theirs nuttin wrong with the way you guys think it may be that simple... It can still throw you a curve ball.... Yes he needs a diagram unless he works on Ford Escorts on a regular basis...
