Land Rover Part Number: JEC001040 - 12V Heater Box Assembly - Right-Hand Drive
JEC001040 is a 12V heater box assembly configured for right-hand drive Defender diesel models. This single-unit assembly contains the blower motor and a coolant-fed heater matrix to provide cabin heat and controlled airflow; warm engine coolant passes through the matrix while the blower forces air across it, which is then routed to the dash outlets and floor vents. The blower motor and heater matrix are not available as separate service items, so replacement of the complete heater box is required if either component fails. Confirm fitment against the vehicle's V.I.N. and right-hand drive configuration before ordering.

Frequently Asked Questions
JEC001040 is a combined blower motor and coolant-fed heater matrix assembly that supplies heated air to the cabin of right-hand drive Defender diesel models. Engine coolant flows through the heater matrix while the blower forces air across it; the warmed air is then routed to dash outlets and floor vents. Because the blower motor and heater matrix are not available separately, the complete heater box assembly must be replaced if either component fails.

Replace the heater box assembly when the blower motor fails, the heater matrix leaks, or there is a significant loss of cabin heating or airflow. As the blower motor and matrix are not supplied separately, the complete unit must be replaced in these cases; confirm fitment with your V.I.N. before ordering.
