Radiator Cooling Fan Control Module for Hyundai Azera Sonata 2006-2009
Restore precise airflow and engine temperature regulation with this direct-fit radiator cooling fan control module, engineered specifically for Hyundai Azera and Sonata models from 2006 to 2009.
When your original control unit degrades, fans frequently run unconditionally, fail to engage, or cycle unevenly—leading to cabin discomfort and preventable heat stress under load. This replacement unit accepts digital signals without independent power draw, replicating factory voltage thresholds to trigger accurate fan speed transitions based on coolant temperature and refrigerant pressure. Compatible with OE references 25385-3K280, 253853K280, and 902424, it plugs directly into your existing harness and eliminates the electrical dead zones that cause recurring cooling complaints.
Benefits & Tips
- Verify OBD-II diagnostic codes first; this module clears constant-fan runtime, intermittent cooling loss, and HVAC sync errors.
- Secure the connector pins firmly before powering the system to prevent arcing and ensure stable signal transmission to the fan motor.
- Run an OBD-II scan reset after installation to purge residual adaptation values and confirm normal idle temperatures.
