Several fuses supply power for the Automatic Temperature Control (ATC) system. When the ignition switch is in the RUN position, it connects circuit A2 from fuse 13 in the Power Distribution Center (PDC) to circuit A22. Circuit A22 powers circuit F71 through fuse 17 in the fuse block. Circuit F71 connects to the ATC module and the recirculation door motor.

When the ignition switch is in the START or RUN position, it connects circuit A1 from PDC fuse 12 to circuit A21. Circuit A2l powers circuit F83 through fuse 5 in the PDC. Circuit F83 powers the coil side of the A/C compressor clutch relay and the A/C low pressure switch.

Circuit A19 from fuse 11 in the PDC connects to the blower power module and to the coil and contact side of the high speed blower motor relay.

Circuit A4 from fuse 1 in the PDC powers circuit F6O through fuse 8 in the fuse block. Circuit F60 connects to the ATC module.
