Frequently asked questions

What does the LR031677 heater resistor control unit do?

The LR031677 heater resistor control unit regulates the blower motor speed in the heating and ventilation system. It modulates current to the fan so it runs at the speed set on the climate controls. It fits the Discovery 4 and Range Rover Sport L320.

Where is the heater resistor located on the vehicle?

The heater resistor control unit mounts inside the heater blower housing within the HVAC system, typically accessed behind the dashboard or in the footwell area. It sits in the fan's airflow, which helps dissipate the heat it generates while controlling speed.

What are the signs the heater resistor needs replacing?

A failing heater resistor typically shows up as a blower that only works on one or two fan speeds, or stops altogether. On the Discovery 4 and Range Rover Sport L320, losing the intermediate fan speeds is a common symptom of resistor failure.

How do I confirm this fits my vehicle?

This heater resistor fits the Land Rover Discovery 4 and Range Rover Sport L320. It's cross-referenced as PCE500010. Confirm your model against these before ordering, and use your VIN to verify the variant.
