Chart C12 - Fan Control Circuit: Notes

The ECM controlled A/C fan relay, when energized, grounds circuit 335 and fan control relay terminal B. This energizes the fan control relay, closing its contacts and supplying battery voltage to the fan motor. If the ignition switch is turned "OFF" and the fan temperature switch is closed, the fan timer relay will continue to supply battery voltage to the cooling fan circuit 903 and the low speed resistor. The fan will run on low speed for about 5 minutes if the temperature switch remains closed and the ignition is "OFF".
