My brother brought his Chrysler Sebring over this morning so I could put the gauges on it to see what it was doing, because the a/c cools the car good when it's on recirculate, but doesn't on regular a/c. I hooked up the low pressure gauge and was attempting to hook up the high pressure gauge when I broke a fitting to it so I didn't get a high pressure reading. With the a/c in normal operation the low side pressure was running about 60 PSI, but when we put it on recirculate it dropped down to near where it should have been about 47 PSI by my gauge. The compressor was running in both modes and the lines were cold and sweating. Does anyone have any ideas what would cause the high pressure during normal operation and not on recirculate?
