Get your fan speeds back under control with the Standard Ignition HVAC Blower Motor Resistor RU-317, a direct-fit replacement for the 1998-2002 Mazda 626. This resistor sets the resistance in the blower circuit that steps the fan motor through its lower and medium speed settings — when it fails, you often lose those intermediate speeds while only high may still work, or the fan quits entirely.
Precise resistance values: premium copper electrical connectors are used to hold more precise resistance values, which improves resistor performance and offers longer part life.
Seamless integration: Standard's research and design process is aimed at seamless integration with the vehicle's HVAC system.
Variable-speed control: restores A/C and heater blower motor variable speed control, helping to optimize HVAC performance and passenger comfort.
Tested performance: undergoes extensive testing at the facility to help ensure correct performance in all conditions.
If a failed blower resistor is the cause of your missing fan speeds, this part replaces it. See the Buyer's Guide tab for engine-specific fitment.
Interchange: RU1012 · JA1168 · BR222 · GD7A61B15 · GD7A61B15A

Frequently Asked Questions
What does this blower motor resistor do?
It sets the resistance in the blower circuit that steps the fan motor through its lower and medium speed settings, controlling how fast the HVAC fan runs at each position.
What vehicles does the RU-317 fit?
It is a direct-fit replacement for the 1998-2002 Mazda 626. Check the Buyer's Guide tab to confirm the application for your vehicle.
Why do only some of my fan speeds work?
A failed blower resistor often knocks out the lower and medium speeds while high may still work. If the resistor is the cause, this part replaces it; diagnose the circuit first.
What interchange numbers does it replace?
It cross-references RU1012, JA1168, BR222, GD7A61B15, and GD7A61B15A.
What are the electrical connectors made of?
Premium copper electrical connectors are used to help hold more precise resistance values, which improves performance and offers longer part life.
