(1997 Ranger XLT 2.3 w/ Factory AC) So I got a manifold gauge set and pulled a vacuum on my system, then put some R134 with lubricant in it into the system.
System reads 50 psi on the low side, and 100 psi on the high side at engine idle, but then the compressor kicks on and they go down to about 30/50 psi.
The compressor is short-cycling and coming on really hard. By that I mean that it cycles for 3 seconds, rests for about 10, and cycles again, and after about 4 iterations of this, it is almost stalling the engine when it kicks on.
The system held vacuum while I was checking it, and still was charged from the other day when I tried just pushing R134 in on a not-vacuumed system.
What am I missing? I followed the charge procedure after replacing the Drier/Accumulator (some idiot put a thermal blanket thing on it trying to prevent condensation, but all that did was trap the condensation and rust out the drier ). I did a little bit of looking over the Auto AC forum and can't seem to find any answers (I admittedly suck at searching, so there's that).
I'm starting to think there may be something electrical like a sensor (yes, I plugged them back in) or a relay. Could there be something wrong with the compressor itself?
