A/C Control
With the ignition switch in ON, battery voltage is applied to the coil of the blower relay from fuse 12. With the blower switch in any position except
OFF, ground is provided to the coil of the blower relay through the blower switch. With the A/C switch in ON, the PCM will ground the coil of the A/C
relay after a short delay to adjust idle speed. Battery voltage will then be applied to the magnetic clutch of the compressor from A/C compressor fuse, to
make the A/C compressor run.
