Land Rover Part Number: LR041273 - Heater Air Mix Stepper Motor - Left-Hand Temperature Control
LR041273 is a Heater Air Mix Stepper Motor - Left-Hand Temperature Control. Fitted to the heater box, this stepper motor positions the left-hand temperature actuator to adjust the mix of warm and cool air delivered to the left seating zone. It converts small electrical control steps into precise angular movement of the temperature flap to enable accurate single- or dual-zone temperature regulation and balance between driver and passenger sides. If the motor fails, left-side temperature control can become unresponsive or remain stuck in a single position; replacement restores normal climate control operation.
