Heater Blower Resistor for the air conditioning climate control system. It regulates the speed of the blower motor, controlling the force of the airflow delivered through the dashboard vents.

The resistor is carried on a thermal-sink aluminium mounting plate that dissipates circuit heat to keep operation stable over its service life. Fitted to 200Tdi and V8 applications equipped with air conditioning.

Vehicle Model Land Rover Discovery 1 1989-1998 (L318)
Range Rover Classic up to 1994

Fitment Notes DISCOVERY 1 — 200Tdi with air conditioning.
RANGE ROVER CLASSIC 1986-1994 — 200Tdi or V8 with air conditioning; retailers narrow this to 1990-1994.
Heater blower motor resistor kit, replacing genuine PRC8010. Air-conditioned vehicles only.

Frequently asked questions

What does the heater blower resistor do?

The heater blower resistor regulates the speed of the blower motor, controlling how much airflow the dashboard vents deliver. It steps the fan between its speed settings on the heating and air conditioning system. It's fitted to air-conditioned Discovery 1 and Range Rover Classic models.

Why does the heater blower resistor fail?

The heater blower resistor typically fails from constant heat cycling through its resistance coils. The usual symptom is losing the lower fan speeds while full speed still works, or the blower stopping altogether. It's mounted on an aluminium heat-sink plate that helps dissipate that heat during normal operation.

Where is the heater blower resistor located?

The heater blower resistor sits in the heating and air conditioning system, typically in or near the heater blower housing so passing airflow keeps it cool. It's carried on an aluminium thermal-sink mounting plate. This part fits 200Tdi and V8 Discovery 1 and Range Rover Classic vehicles with factory air conditioning.

How do I confirm this heater blower resistor fits my vehicle?

This heater blower resistor fits Discovery 1 (1989-1998) and Range Rover Classic (up to 1994) equipped with factory air conditioning. It's specific to air-conditioned vehicles, so confirm yours has A/C before ordering. It carries a 2 year guarantee.
