Thanks for you help with my issue. I recharged the system using the Pressure chart you provided and the system is cooling well ... Pressure-Temperature Guide for A/C. Key: Green (in of Hg) = Vacuum. Black (psig) = Saturated Vapor (calculate superheat). Bold (psig) = Saturated Liquid ... Does anyone have the chart from the service manual or at least the low/high side a/c pressure ranges for the different ambient temps? Â At least twenty-five PSI of static pressure is required, or the cycle switch may disable the compressor. What is normal automotive air conditioner pressure? Low side pressure should sit right at 30psi at all times the compressor is on, within a couple psi is OK. High side pressure will change ... emzone A/C Temperature/Pressure Chart. TEMPERATURE.
