Jaguar, Land Rover, genuine stepper motor No: LR035739

LR035739 is a Heater Stepper Motor fitted within the heater main unit of Range Rover L405 models. The stepper motor converts electrical pulses into precise incremental rotary movement to position internal flaps and valves that control airflow routing and temperature blend within the climate control assembly. Accurate incremental control reduces audible stepping and helps the heater unit reach commanded settings from the vehicle control modules; when replacing the component, match the part number to ensure the motor's electrical connector and mounting align with the heater main unit on the specified model years.
