P0692 on Jeep by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Engine temperature gauge rising above normal in traffic
- Cooling fans audibly not running or running slowly at idle
- A/C compressor cuts out unexpectedly in hot weather
- Overheating warning message on instrument cluster
- Check engine light with fan control related fault codes
How to Fix
Replace the integrated fan control module (FCM) mounted near the radiator assembly. Updated module part numbers have been released by Mopar to address thermal reliability. Inspect cooling fan wiring harness for chafing near the module connector, as wiring damage can mimic module failure. Coolant system inspection and flush recommended simultaneously.

Frequently asked questions
What does P0692 mean on a Jeep?
P0692 stands for "Fan 1 Control Circuit High." This code means the engine computer detected high voltage (or an open circuit) in the control circuit for cooling fan 1. The PCM commands the fan through a relay and watches the circuit voltage; a high reading usually indicates an open or a relay/wiring fault. If the fan fails to run, the engine can overheat at idle or in slow traffic. On Jeep it is documented across 1 model: Grand Wagoneer.
What are the most common causes of P0692?
The most common causes of P0692 are: Faulty cooling fan relay, Open circuit in the fan control wiring, Failed cooling fan motor, Corroded or disconnected fan connector, Blown fuse feeding the fan circuit, PCM control driver fault. The specific cause varies by vehicle.
How much does it cost to fix P0692 on a Jeep?
Published repair estimates on Jeep range from $450 to $1,600 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
