First thing I check on these things is the hub/idler pulley gap for 20 mils, these hubs are pressed on and tend to press off. Then I hot wire the compressor clutch with a remote starter switch with gauges attached to check for proper operating pressures to make sure that is operating properly. Using the remote starter switch lets me quickly turn it off, don't want to run that compressor with low operating pressures, can damage it.
If real low, like zero on both sides, check the entire system for oil leaks, add some R-134a, EPA doesn't mind if you waste a pound for this then get out the electronic leak detector. Have to find the leak and repair it. If static pressure is good, but runs low, very typical for an R-134a to lose about 10% per year, ten years adds up if the system was never topped off before. If all looks okay, then checking the condenser and evaporator for debris and proper fan operation, you cannot properly charge a system by pressures with any debris in these systems. Believe this vehicle uses the variable displacement V-5 compressor, and these are exceptionally difficult to charge by pressures, should recover and charge by weight. These also run full time, don't cycle like the older ones did, more like how the real old ones worked back in the 60's with the POA valve.
Once the system is leakproof, and charged properly, and works great with the remote starter switch, rehook up the compressor connector, if it doesn't work then, that is when you dig into electrical problems.
When my stepdaughters AC quit working last summer with recent hand surgery, had to tell her to roll down the window, she survived. But getting under her car this year, the reason for AC not working was obvious, compressor outlet hose was rotted out. No need to put gauges on that. Good to start off with a good visual inspection off the system. All depends on how your system died, can be a normal slow leak with noticeable poorer and poorer performance, or a stone chip on the condenser. Kind of like it worked great one day and failed the next.
