Where's the EPR (evaporator pressure regulator) on a 3.0L V6 '91 Caravan. It has the 6C17 compressor, variable displacement type. Is it one of the valves that is held in by snap rings on the compressor? If so how do you adjust it? Remove the snap ring and turn it? Or just turn the screw head on the top, is there any locking device to hold it in?
