How warm was the engine compartment? If the engine has been running--or even getting a heap of solar radiation--warming-up the underhood equipment, your pressures will reflect the temp of the system, not the ambient temp.I hooked up the gauges (following a video) with nothing running... ...Temp was about 85 F and 37% relative humidity.
Based on the 158-psi indication, the engine compartment must have been about 115 degrees. Seem reasonable?You must be registered for see images attach
Not my first choice, since it's got refrigerant and enough pressure to run the compressor. Find out why the compressor doesn't work.Flush the system next?
Yup. High side at 158, low-side needle pegged 'cause the gauge doesn't go to 160.perfectly normal for the gauges to read the same pressure when the system has been sitting static
Nope. When running on a hot day, the high-side can go over 300 psi.That's not too much pressure to try and run the system?
Probably on the accumulator / receiver-dryer. Didn't you replace that? Did you transfer the low pressure cutout switch from the old one? (Or am I thinking of another person with A/C issues?)Where is the LP switch connector?
Thanks for that. I've saved that chart for future reference.Not when ambient temps are high, use the chart posted here,

Hi guys, I just finished redoing my AC. In my 99 2 door Tahoe with no rear AC. I went with a Delphi compressor, ACdelco dryer, hoses and a rockauto condenser and a 4 seasons orifice tube. Everything went smooth..added 32 oz of Freon and it’s blowing really good. Only issue I am having is the...www.gmt400.com
