I have similar problem with my 91 P/A No trouble codes. A/C compressor would engage in auto, then revert to econ. The clutch separted on the compressor so I replaced compressor, flushed components, new orifice, and recharged with R134a. Original problem still present. I can clear codes and press HI then compressor engages and operates for about 1 minute or less then kicks out. It will remain in ECON until I reset during self diagnostics. Low side drops to 25-35 and High side 170 to 230 any insight would be great. This has been expensive enough so far and I don't want to just shot gun unnecessary parts.
