Chrysler Repair: Code 33, AC Relay Circuit Open Shorted, dodge caravan, relay circuit


Question
QUESTION: 1994 Dodge Caravan, 3.3L

PROBLEM
Keep receiving a code 33 after about 5/10 minutes vehicle operation whether or not A/C is on.  A/C works great

FAULT CODE
Per search full code description is:
33  Air conditioning clutch relay circuit open or shorted
    (may be in the wide-open-throttle cutoff circuit)

---------------------------------
QUESTIONS:

1) Where can I obtain a circuit diagram (don't have access to Mitchells, AllData, or Shop Manual this vehicle.  My understanding Hayes has little.)

2) Suggested or best approach to troubleshoot this circuit?

3) Other suggestions or circuits that may be triggering this code?


ANSWER: I dont have diagrams for it either to old.
Find the relay  and see what u have   With key one U should have 2 powers and one ground and on wire going to the compressor it self.

QUESTION: Kevin:

Thanks for response.  

Compressor has two wires going to clutch.  
Assume by your comment both are power (white and black) and ground is chassis ground from Compressor body.  Odd wire color for power since black normally ground.

Any idea if there is an A/C relay and where located if  independent of compressor internals?

---------------
In Tucson, AZ so Atlanta a little hike for this problem.  Hope your water situation is improving.  This is big issue
here continually.


Answer
one would be power and one would be ground no chassis ground. I have Mitchel on demand but cant take pics off there and post them. There should be a connector that the 2 wires go into go there and the colors should change to a better suited match. One always ground  and one power only when the clutch is to be active.
