A/C CLUTCH WILL NOT ENGAGE

1998 Plymouth Voyager

Air Conditioning problem
1998 Plymouth Voyager 6 cyl Two Wheel Drive Automatic 74000 miles

My 98 Plymouth Gran Voyager A/C clutch will not engage. The system has adequate refergerant. Trouble shooting has revealed that the A/C clutch relay solenoid does not have a ground. The Plymouth service manual states that the PCM operates the clutch relay ground circuit. I am assuming that I need to replace the PCM, but before I buy one I would like to have a second opinion that it is the PCM.

Thanks,

When the PCM grounds the coil side of the AC clutch relay it powers the magnetic clutch to engage the compressor
