If a failed resistor has left your heater and A/C fan stuck on one speed or dead on some settings, the Standard Ignition Blower Motor Resistor RU-381 is designed to restore variable fan-speed control. It fits many vehicles, among them the 2002-2006 Ford Explorer, 2003-2006 Ford Expedition and 2007 Ford Explorer Sport Trac, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
This HVAC blower motor resistor works in the blower motor circuit, supplying different resistance values so the fan can run at the speed you select. When a resistor fails, some fan speeds can drop out or the blower may stop working altogether. It is cataloged for front and rear positions.

This part cross-references / interchanges with the following part numbers:
Will this work as a Ford Expedition blower motor resistor?
Yes. It's a direct-fit replacement for the 2003-2006 Ford Expedition. See the Buyer's Guide tab for engine details.
Is this the right 2006 Ford Explorer blower motor resistor?
Yes. It's listed for the 2002-2006 Ford Explorer and also fits the 2007 Ford Explorer Sport Trac.
What does a blower motor resistor do?
It supplies different resistance values in the blower motor circuit so the heater and A/C fan can run at the different speeds you select.
What are signs a blower motor resistor may need replacing?
A fan that works on only some speeds, runs only on high, or won't run at all can be a sign. Check the switch, motor and wiring too, since they can cause similar symptoms.
What sets the Standard RU-381 apart?
It uses premium copper electrical connectors for more precise resistance values, and it is extensively tested at Standard's facility for correct performance.
