Compressor operating pressure or link for Silverado service manual.
Would anyone happen to have a link to an online service manual for my 04 Silverado 5.3?
Or if you know the operating pressure I should look for on my compressor, high and low side.
Thanks.

Normal pressure ruling says 35-40 low, 200-250 high.
After replacing the seals and vacuuming, I hooked the manifold gauge up and put one can of freon into the system. (12 oz can) before my coolant leak sprung. I halted the operation and attended to the loose hose yesterday. Last night I tried to finish what I started, but the low side sat at 40 psi while the high side floated around 235-250. I put in a few ounces of PAG and tried to add another 12 oz can, but my compressor wouldn't kick on and allow the freon to feed into the system. (Yet it was working JUST FINE when I added the first can.) It's acting like the system is full and my clutch woule only engage when my buddy hopped inside and pressed the peddle to about 2k RPM. Felt the lines around the evaporator, low side felt cold and high side was warm. The compressor is engaging so I assume that's not my issue here.

ccot sytem the low pressure switch is designed to shut down the comp at 26psi. if that occurs it won't start back up till 46psi. that is factory spec.
put manifold gauges on report actual pressures; otherwise it guess work.
