With the ignition switch in the ON position, system voltage is applied to the A/C 1 relay (compressor clutch) through the HEATER fuse. The A/C 1 relay (compressor clutch) is energized when the A/C compressor control module grounds the coil of the relay. With the A/C 1 relay (compressor clutch) energized, voltage is applied through the A/C fuse and the closed contacts of the A/C 1 relay (compressor clutch) to the coil of the A/C 2 relay (condenser fan). Since the A/C 2 relay (condenser fan) is permanently grounded at G102, the relay energizes, the contacts close, and voltage is applied to the A/C condenser fan motor. Because the A/C condenser fan motor is permanently grounded at G103, the cooling fan operates as soon as voltage is applied.
