Engine Cooling Fans
WARNING: This page is about a different car, the 2002 Saturn LW300 and 2002 Saturn L300. However, it is still accessible from the selected car via links, so may be relevant.
A fan control module is used by the ECM to control engine cooling fan operation. The engine cooling fans are turned On or Off by the ECM dependent upon engine coolant temperature or A/C system pressure.
Under high ambient conditions, the cooling fans and heater water pump may run for several minutes after the key is turned Off.
