What are the proper High and Low AC pressures for 2001 Cadillac Deville? I have a chart attached from a member's posting.. Can anyone verifythe pressures ar correct from the FMS? What is what is in the FSM? I am going to get a copy soon but have not received it yet.. I am trying to add refrigerant to my caddy to stop the warm air coming out of the drivers side AC outlets. The low pressure was at 30 psi and I added R-134a to 40 psi, helped but did not stop the warm air, but I then got the chart below and in Florida where we are at 85-90 degrees it apparently should more like 50 psi on the low side..Hellllp.
