P0480 on Jeep
Cooling Fan 1 Control Circuit
P0480 on Jeep vehicles indicates cooling fan 1 control circuit. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. P0480 indicates a fault in the engine control module's circuit that operates cooling fan 1 (or the fan relay it drives). The computer detected an open, short, or out-of-range condition in the fan control output. Because the cooling fan helps prevent the engine from overheating — especially at idle, low speeds, or with the A/C on — a fan that won't run can lead to high coolant temperatures. It is worth addressing fairly promptly to avoid overheating, particularly in hot weather or stop-and-go traffic. Typical repair costs on Jeep range from $450 to $1,600, depending on the specific model and root cause.
Common Causes of P0480
- •Faulty cooling fan relay
- •Failed cooling fan motor
- •Wiring damage, shorts, or corroded connectors in the fan circuit
- •Blown fuse or fusible link for the fan
- •Poor ground for the fan motor or relay
- •Faulty fan control module (where used)
- •PCM driver circuit fault (less common)

- Cooling Fan Module Failure / Overheating Warning2021-2023
The electric cooling fan module on the Grand Wagoneer has been documented to fail, causing the dual electric radiator fans to run at reduced speed or stop entirely, resulting in engine coolant temperature spikes especially at low speeds and in traffic. The fan control module can develop internal MOSFET failures due to heat cycling, and Stellantis issued related service guidance through their dealer network. Owners report the temperature gauge rising into the red zone during stop-and-go driving and the A/C compressor cutting out as a secondary symptom.
