    hey man, i see you're very knowledgeable on A/C stuff. wondering if you can help me out:

    I'm dealing with this issue now, but it only happens once I get to about 2000-2500 rpms, and no matter what I charge it up to (I've tried 35, 40, 45, 55 psi), it continues to to cycle on and off every 5 seconds or so. When I have the guage on it, I can watch it drop as the RPMs increase and as soon as it drops below 25 psi (into the white on the gauge) the cycling starts.



    BTW - when I got the truck the compressor was dead, so I've put on a new compressor, dryer, evaporator, orifice tube, flushed and vacuumed the system, and charged with 134.

    Someone mentioned to me that maybe the pressure switch should be changed to one with a lower cut off, since 134 runs at a lower pressure that r12?

    Any advice?

    Hello again. I seen the dash bezel,gauge cluster and wiring harness. How much all together? My 87s got no air and the same gauges, and redneck wiring. Drives nuts, I replace sections when I have absolutely nothing else to do lol. PO didn't believe in wire ends or heat shrink.
