This is a critical part for the First Gen Ford Escape Hybrid (and its twin, the Mercury Mariner Hybrid). If this fan fails, the High Voltage (HV) battery will overheat, leading to poor fuel economy, "Triangle of Death" warning lights, or the car refusing to stay in EV mode.
Location: This blower is located inside the HV battery pack in the rear cargo area. It draws air through the driver-side rear quarter window vent.
Function: It cools the NiMH battery cells. 2005–2008 models usually have two fans; 2009–2010 models transitioned to a slightly different internal cooling setup, but the blowers remain the most common failure point.
