Beck/Arnley HVAC Blower Motor Resistor P/N:204-0021
Keep every fan speed working with the Beck/Arnley Blower Motor Resistor 204-0145 — a direct-fit Mazda 3 blower motor resistor for the 2010-2013 Mazda 3. This resistor sits in the HVAC blower circuit and provides the resistance that steps the blower motor's voltage up and down, giving you the different fan speeds selected at the climate control. If a failed resistor is the cause of your lost fan speeds, this replaces it.
Beck/Arnley parts are designed as direct replacements for Original Equipment applications across foreign nameplates, with special attention to form, fit and function. A common sign the original resistor has failed is a blower that runs only on high (or only certain speeds) while others go dead — diagnose the cause before replacing, since wiring, the switch, or the blower motor can produce similar symptoms.
Fitment: 2010-2013 Mazda 3. See the Buyer's Guide tab for the full application details.

This part cross-references / interchanges with the following part numbers:
What vehicle does the Beck/Arnley 204-0145 fit?
It is a direct-fit blower motor resistor for the 2010-2013 Mazda 3. Check the Buyer's Guide tab to confirm it matches your specific vehicle.
What does a blower motor resistor do?
It provides the resistance that steps the blower motor's voltage up and down, producing the different fan speeds you select at the climate controls. Only the highest speed typically bypasses the resistor.
Where is the Mazda 3 blower motor resistor location?
Blower motor resistors mount in the HVAC blower housing or air duct so passing airflow helps cool them. Refer to the vehicle service information for the exact location on your Mazda 3.
What are signs my blower motor resistor may need replacing?
A common sign is a blower that works on only one speed (often high) while other speeds are dead. Diagnose first, since the switch, wiring, or blower motor can cause similar issues.
What interchange numbers does this resistor replace?
It cross-references 2400635296, RU1595, BBM461B15, RU906, WP332560OES, and 4P1711.
