Dodge Radiator Fan Wiring Diagram
How Dodge Radiator Fan Wiring Diagram is set up
Some Dodge vehicles have a solid state radiator fan controller that varies the fan speeds by pulsing the ground to the radiator fan motor. But other Chrysler and Dodge vehicles use a more traditional radiator fan relay. This is the Dodge Radiator Fan Wiring Diagram for the traditional version.
How Dodge Radiator Fan Works
The powertrain control module (PCM) sends a reference voltage to the engine coolant temperature sensor and monitors the return voltage. When it determines the engine requires cooling, it grounds the control coil in the radiator fan relay. That energizes the coil and causes the relay contacts to close. Power then flows from the fuse in the integrated power module through the relay contacts and to the radiator fan motors.
