Re: 2000 S-10 4.3L V6 AC Replacement Questions

OK, I re-verified gauge readings as of right now.

Outside temp: 78, RH = 82%

@ Idle, 600 RPM, gauges read: 40psi, low, 210psi high

@1800 RPM, low = 29psi, 260psi high

Again, this is with paper clip jumpering the low-side pigtail.... if I plug pigtail back into the low-side switch, system runs for around 10 minutes and then shuts off (and may randomly start again, may not). If you shut off car, and turn back on, compressor comes right back on.... If engine is on and it cuts off, it may come back on if I "jiggle" the pigtail a bit.

Leak? or bad switch? System was pressurized at 6pm last night.... about 16 hours ago, or so....
