The auxiliary cooling fan, if equipped, provides additional cooling under the following conditions:

In cases of extreme coolant temperatures, the fan runs after engine shutdown. The auxiliary cooling fan is behind the grille on the right side of the vehicle.

The auxiliary cooling fan circuit consists of the following components:

Once the VCM determines that the fan activation is appropriate (a function of coolant temperature, vehicle speed, and A/C system status), the VCM completes the ground side of the circuit to the relay coil. This energizes the relay, providing 12 volts to the auxiliary fan.

When the VCM determines that the fan operation is no longer required, the relay is de-energized, and voltage is no longer applied to the fan. Refer to Engine Controls for circuit schematic and diagnostic procedures.
