2002 Saturn SC2 1.9L compressor clutch VIN: 1G8ZY127X2
only one of the three replies i recieved agreed with me, in that BCM to PCM module comunication is the problem, and that the BCM is the most likely culprit! at $480 cdn for a BCM, it made sense to spend a little more of my time and try swaping a BCM out of ano...
