Operating Context

The motor provides rotational force for the cooling fan after receiving the vehicle control command through the correct electrical circuit.

Unusual noise can come from motor bearings, a cracked blade, loose mounting or foreign material in the fan area.

Overheating does not by itself prove motor failure; coolant flow, radiator condition, sensors and broader fan controls also require inspection.
