Thought would update for others that might have this issue
Symptom - No cold AC, compressor clutch does not engage
Troubleshooting
1) Test compressor clutch engages (unplug compressor and jump from battery)
2) Use gauges to check refrigerant pressure
Engine and AC off (static - is refrigerant in system, pressure dependent on temp and humidity)
Engine running and AC on, check numbers per service manual)
Needed to unplug compressor and jump from battery
Numbers were close to service manual recommendations (ran 5 - 10 mins)
At this point appeared to be electrical in nature....
3) Check pressure switch on condenser (used continuity tester), next checked for pressure switch voltage, tested good (need ignition switch on).
NOTE: per the schematic it shows a 'dual pressure (high/low) switch'
NOTE: Page 756 of 15 series service manual
Since blower, AC button appeared to work decided to verify the anti-freezing sensor (left side, 2 wire plug, part of evaporator in roof), checked out good
4) Engine running, blower motor set to 2, AC on, checked for power on compressor relay plug (labelled E1 and is blue/white wire), no power. Removed and tested per service manual (used example page 775) and found continuity bad.
5) Replaced compressor relay and AC blowing cold air....

(So far.... LOL)
