Beck/Arnley HVAC Blower Motor Resistor P/N:204-0021
Keep the fan spinning through every setting with the Beck/Arnley Blower Motor Resistor 204-0039 — a Toyota 4RUNNER blower motor resistor that also serves the Land Cruiser. It drops in as a direct replacement for the 1996-2002 Toyota 4Runner and the 1998-2007 Toyota Land Cruiser (see the Buyer's Guide tab for engine-level fitment). This is the REAR-position resistor, so it manages the rear HVAC blower's speed circuit.
A blower motor resistor sets the different fan speeds by adding resistance to the blower motor circuit; when it fails, the fan often works on high only or drops certain speeds. If a failed resistor is the cause of those symptoms, this unit replaces it.

This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It adds resistance to the blower motor circuit to set the different fan speeds. When it fails, the blower often runs on high only or loses some speeds.
Does the 204-0039 fit a Toyota 4Runner?
Yes. It is a direct replacement for the 1996-2002 Toyota 4Runner and the 1998-2007 Toyota Land Cruiser. Check the Buyer's Guide tab for engine-level fitment.
Is this a front or rear resistor?
This is the REAR-position blower motor resistor, controlling the rear HVAC blower's speed circuit for the listed applications.
Where is the Toyota 4Runner blower motor resistor located?
It mounts in the HVAC housing on the blower circuit. Location varies by model, so consult the vehicle service information to find and access it.
Will replacing this fix my fan that only works on high?
If a failed resistor is the cause, replacing it restores the missing speeds. Other issues like the switch or wiring can cause the same symptom, so diagnose first.
