Ford Electronic Fan Cooling Speed Control Resistor Module XS6H9A819BB 1364715 Cooling System Durable Part

Ford electronic fan cooling speed resistor module (OEM: 1364715 / original XS6H9A819BB) integrated into the cooling fan assembly; automatically adjusts fan speed based on engine temperature to precisely control cooling intensity. Fits Ford Focus, Mondeo and most Ford models; installation requires removing the fan shroud and attention to wiring harness orientation; labor about 30-45 minutes. If air conditioning cooling drops, coolant temperature runs high, or the fan only has high-speed with no low-speed, the internal resistor module is likely damaged and should be replaced.
