Frequently asked questions

What does the LR031677G heater resistor control unit do?
The LR031677G heater resistor control unit regulates the heater blower motor's fan speed within the HVAC system on the Discovery 4 and Range Rover Sport L320. It modulates the current supplied to the blower motor to set each speed selected at the climate controls, and mounts within the heater/blower housing.
Where is the heater resistor fitted on a Discovery 4?
The heater resistor control unit sits within the heater/blower housing in the heating and ventilation system. It's typically located near the blower motor under the passenger side of the dashboard, wired inline between the climate control and the blower motor.
What are the signs the heater blower control unit is failing?
A failing heater resistor control unit typically shows as the blower working on only one speed, usually full, or cutting out intermittently. On the Discovery 4 and Range Rover Sport L320 this unit handles all fan speeds, so a fault often leaves the fan stuck or dead rather than variable.
How do I confirm this fits my Discovery 4 or Range Rover Sport?
This fits the Land Rover Discovery 4 and Range Rover Sport L320, both from VIN AA000001. Use your VIN to confirm the build falls at or after that point. The official Land Rover reference is LR031677, with alternative PCE500010.
