Compressor Clutch: Testing and Inspection

COMPRESSOR CIRCUIT

CIRCUIT DESCRIPTION

The air conditioning amplifier outputs the magnetic clutch ON signal from the MPX terminal to the ECM which receives this signal. It then sends the
signal from the ACMG terminal and switches the magnetic clutch relay on, thus turning on the magnetic clutch.
