Take back control of cabin airflow with the Standard blower motor resistor, part number RU-906. It is designed to restore variable speed control to your A/C and heater blower motor, and it is a direct-fit replacement for the 2010-2013 Mazda 3 and the 2012-2013 Mazda 3 Sport.
The HVAC blower motor resistor regulates how much current reaches the blower motor, which produces the different fan speed settings on your climate controls. Signs this part may need replacing include a fan that runs only on its highest setting, speed settings that no longer respond, or a blower that won't run at all. If a failed blower motor resistor is behind the problem, RU-906 replaces it.
See the Buyer's Guide tab for complete application details.

This part cross-references / interchanges with the following part numbers:
What does a blower motor resistor do?
It controls how much current reaches the blower motor, which gives the A/C and heater fan its different speed settings. RU-906 is designed to restore that variable speed control on the listed Mazda applications.
Is RU-906 the right blower motor resistor for a 2010-2013 Mazda 3?
Yes. RU-906 is listed for the 2010-2013 Mazda 3 and the 2012-2013 Mazda 3 Sport; see the Buyer's Guide tab for complete application details.
Where is the blower motor resistor located?
The exact mounting location and access steps vary by vehicle, so consult the vehicle service information for your vehicle before removing the original resistor.
What are signs my blower motor resistor may need replacing?
Common signs include a fan that works only on its highest setting, missing speed settings, or a blower that won't run. Other faults can cause these symptoms, so diagnose the cause before replacing.
What sets the Standard RU-906 apart?
It uses premium copper electrical connectors for more precise resistance values, is designed specifically for Mazda applications, and undergoes extensive testing at Standard's facility.
