Four Seasons HVAC Blower Motor Resistor P/N:20181
Get your fan speeds working again with the Four Seasons HVAC Blower Motor Resistor (P/N 20685), a direct-fit Ford Focus blower motor resistor for the 2008-2011 Ford Focus. Wired into the blower motor circuit, this resistor sets the resistance that steps the fan through its lower speed settings — so when a failed resistor is the cause of a heater that only blows on high (or certain speeds cutting out entirely), this replaces it.
Signs this part may need replacing include a blower that runs only at full speed, missing intermediate fan speeds, or no airflow at all. Diagnose the cause before ordering, since these symptoms can also come from the switch, motor, or wiring.

This part cross-references / interchanges with the following part numbers:
What vehicle does this blower motor resistor fit?
It is a direct-fit replacement for the 2008-2011 Ford Focus. Check the "Vehicles it fits" section to confirm it matches your specific vehicle.
Is this the right part for a 2009 Ford Focus blower motor resistor?
Yes. This Four Seasons resistor (P/N 20685) fits the 2008-2011 Ford Focus, which includes the 2009 model year.
What does a blower motor resistor do?
It adds resistance to the blower motor circuit to set the lower fan speeds. Without it, the fan typically works only on its highest setting.
My Focus fan only blows on high — is this the fix?
That is a common sign of a failed resistor, so if the resistor is the cause this replaces it. Confirm the switch, motor, and wiring are good before replacing.
Does it use the factory connector?
It features OE-style connectors designed to mate with the factory harness, and quality contacts for proper conductivity for a straightforward install.
