Compressor Clutch: Description and Operation
With the ignition switch in START and the transmission control lever in park or neutral (automatic transmission), or the clutch pedal depressed (manual transmission), voltage is applied to the starter relay and the relay energizes. When you turn the ignition switch to ON with the engine running, the relay deenergizes and voltage is applied from the alternator to the heater and A/C relay through the normally closed contacts of the starter relay. The heater and A/C relay energizes, allowing voltage to be applied from FL-1 (MAIN) fusible link to the A/C switch, the A/C pressure switch, and the A/C compressor relay through fuse C-20. When the A/C switch is switched ON, voltage is applied to the coil of the A/C thermostat relay. Ground is provided to the coil of this relay through the electronic thermostat unit and the blower switch (provided the blower switch is not in the OFF position).
