Wholesale Supply Information

Global buyers can request pricing with part reference, quantity, destination and packaging preference.

Typical delivery is 30–45 days depending on quantity and destination; current timing is confirmed in the quotation.

System Function and Diagnosis

As an application-specific electronic unit, it should be identified by OE reference, housing, connector and pin layout rather than appearance alone.

Electronic components should not be replaced solely from visual appearance or a single symptom.

A fan that runs continuously or not at all can result from wiring, temperature inputs, A/C pressure data, motor faults or control logic beyond the module.

Buyer Questions

Why should the fan motor be tested first?

A seized or high-current motor can overload the control circuit and damage replacement electronics.

Is professional diagnosis recommended?

Yes. Cooling-fan controllers operate in high-current, vehicle-specific electrical systems.

Does a non-running fan prove the module is faulty?

No. Test power, ground, wiring, sensors, relays and fan motor condition before replacement.

Can similar-looking modules be interchanged?

Not safely without verified OE and circuit compatibility; internal calibration or pin functions may differ.
