How does the cooling fan work on a Dodge Challenger?

During high speed mode, the cooling fan motor and resistor operate in parallel to one another, with each receiving a separate 12 Volt source. During low speed mode: The PCM grounds the (N201) Fan Relay Control circuit, closing the relay to connect the (A16) Cooling Fan 12 Volt Supply circuit to the (N23) Cooling Fan Motor 1 Output circuit.

What is the ground circuit on a Dodge Challenger?

The (Z903) Ground circuit provides the ground path for the Cooling Fan series circuit. During High speed mode: The PCM grounds the (N201) Fan Relay Control circuit and the (N112) Fan Relay Control circuit, closing all three Cooling Fan Relays.

Can a short Fry a Dodge Challenger controller?

Why is the radiator fan not working on my Dodge Charger?

Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp. Your Charger’s radiator fan will not kick on. If you do have low coolant, don’t fill it up until the engine has cooled off.
