So what do you do if the ac clutch relay controls the ground side of the clutch,,, It looks that way to me he better be looking for a wiring diagram....
The relay is in one of those black box's that resembles a EI control module :twisted: ...

Quoting Removed, click Modern View to seeNOT wanting to get in a whizzing contest with ya hobo (hardly keep from wetting my shoes anyway), but my advice to dan is still good. If it is 'ground controlled', then the clutch connector must have 2 wires, so apply 12 to one and ground to the other. I, too, always like to have a diagram, but don't always & must be more careful then.

Its not a whizzing contest I understand were Y'all are coming from and respect Y'all's advice his issue is going to be accessibility as in its well buried...
A quick shade tree test would be to lay a steel bar on the end of the clutch hub (play safe) if it magnetizes the bar when the AC clutch is commanded on the system controls are working... If so it could be a worn/weak clutch assay are a voltage issue... It would be a rare event to see a open AC clutch field coil....

It could be as simple as the air gap needs to be reset...

But my first check would be to attach AC gauges...
:wink:
That does bring up a question "if refrigerant is heaver that air how does it end up in the upper layer of the O-zone"...

Hmmmm - you test for 12V (presumably) power present at the clutch solenoid and then ground it instead? A wiring diagram is always better than guessing anytime you are trouble shooting an electrical control circuit. A diagram AND a functional description is even better :roll:

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...
