مروحة تبريد البطارية الهجينة معيبة

The fan that is most of the traction battery's cooling system, misbehaving — and "faulty" here means choked more often than broken. The fan breathes cabin air through a floor-level intake that inhales dust, fibre and pet hair for years, so the classic finding is a rotor packed with felt, dragging far below design speed while measuring electrically fine. Cleaning precedes condemnation, and a replacement fitted behind a blocked intake fails the same way.

The stakes are asymmetric: the fan is a modest part, but heat is what ages battery packs, so a fan quietly underperforming for two summers can cost a four-figure pack. That is why the fan codes deserve more urgency than their symptom-free presentation suggests — and why a battery deterioration verdict should always prompt the question of whether the fan ever got cleaned.
