Hi KHLow2008,
Thanks for the reply. I was able to borrow a set of R134 gauges and took some readings.
Ambient air temperature 80
Gauges connected, engine on, compressor off:
Both low and high side 105.
With compressor on, idling 1200 RPM:
Low side 32-35, High side 230-232
With a storm front coming through, the temperature was lower than the level the failure normally occurs at. I had parked in the shade, but it was hot (low 90's) before the front came through. When I first tried to take the readings, the compressor would not start. I ran the engine for 3-4 min. @ Idle and the pressure equalized 105 on both the high and low sides before the compressor finally came on. I was pressing the A/C switch on & off inside the vehicle during the period before the compressor started.
I'm stumped.
