Four Seasons HVAC Blower Motor Resistor P/N:20477
Four Seasons HVAC Blower Motor Resistor P/N:20477
$29.99

Keep every blower fan speed working with the Four Seasons HVAC Blower Motor Resistor 20477. It drops in as a direct-fit replacement for the 2004-2009 Mazda 3 and the 2009 Mazda 3 Sport [All], controlling current to the blower motor so the fan runs at each of its lower settings instead of only high. When a failed resistor is the cause of your climate fan working on just one speed, this replaces the worn unit.

  • OE-style connector: rectangular, 4-terminal female connector for a plug-in fit.
  • Fixed 3-speed resistor: meters current through the blower circuit to set the lower fan speeds.
  • Vehicle-specific application: precision-engineered for the listed Mazda applications.
  • Backed by Four Seasons: engineered and tested for years of trouble-free operation from over 50 years of mobile A/C experience.

Made in Taiwan. If your blower only blows on the highest setting, or one or more speeds have stopped working, the resistor is a common cause worth diagnosing before replacing.

Frequently Asked Questions

What does this blower motor resistor do?

It adds resistance to the blower motor circuit so the heater/AC fan can run at its lower speed settings rather than only high.

Which vehicles does the 20477 fit?

It's a direct-fit replacement for the 2004-2009 Mazda 3 and the 2009 Mazda 3 Sport [All]. See the Buyer's Guide tab to confirm your vehicle.

My blower only works on high speed — is this the part?

A failed resistor is a common cause of that symptom. Diagnose the resistor and circuit first; if it's faulty, this unit replaces it.

What connector does it have?

It uses an OE-style rectangular, 4-terminal female connector for a plug-in installation.

Where is this resistor made?

Country of origin is Taiwan. It's backed by Four Seasons and its 50-plus years of mobile A/C experience.
