Last night I did some more work and proved beyond a doubt that my compressor is indeed shot. Using procedures I gleaned from Sanden's website, I saw that the pressure between the high and low side would equalize in only 20 seconds after being turned off. The spec is at least 2 minutes. I then recovered enough Freon so that the compressor would cycle normally, 7 sec on, 9 sec off. I went on a test drive and everything worked well for about 5 minutes, then quit. Returning home and connecting my gauges, I saw that the pressure in both the high and low sides was 80 psi. I believe the compressor is toasted. I'll update after I install a new one. Many thank to all who have replied!
