{"product_id":"heater-motor-resistor","title":"Heater Motor Resistor – DA4178RESISTOR","description":"\u003cp\u003eThe heater motor resistor controls the blower fan speed by varying electrical resistance across the motor circuit, enabling the driver to select different airflow levels through the cabin heating and ventilation system. A failed resistor typically results in the blower fan operating only on the highest speed setting, or failing to operate on certain speed positions entirely. Replacing the resistor with a correctly rated unit restores full multi-speed functionality to the heater system.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDirectly replaces the original resistor pack, restoring all fan speed settings\u003c\/li\u003e\n\u003cli\u003eDesigned to match the original electrical resistance values and connector configuration\u003c\/li\u003e\n\u003cli\u003eSupplied as a single unit to OEM specification for direct fitment\u003c\/li\u003e\n\u003cli\u003eWhen replacing the resistor, inspect the blower motor and wiring connector for heat damage, as a failing motor can cause resistor burnout\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003ePlease refer to the product title and check compatibility with your specific Land Rover model, model year, and engine variant before ordering.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
