A/C Compressor Control
The climate control unit sends an A/C signal to the PCM via the main fuse block and
instrument cluster (PJB and instrument cluster) based on signals sent from the A/C
switch, fan switch and evaporator temperature sensor.
The PCM controls the A/C relay and IAC valve based on the input signal from the
climate control unit and refrigerant pressure switch.
