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.
