Problem Child
96 Explorer, 4.0 Eddie Bauer, 101,000 Miles
AC compressor does not engage. Ambient Temp. 90DegF,Low port pressure 55 psi, High side 60 psi.
I shorted the low pres. cycling switch and the compressor engaged and went into short cycle mode ( cycling off the high pressure switch, even though gage never went above 60 psi), the low pres gage went to 60 psi compressor off to18 psi compressor on. I assumed this meant low on freon.
This evening as I prepared to add freon the compressor will not engage even with the low side cycling switch shorted. I have 13.5v at the cycling switch but nothing at the clutch. Are there any other system permissives that would interrupt voltage to the clutch.
Also, does this thing have an orfice valve or an expansion valve, as I understand an expansion valve is a dealer installed part i.e expensive.
