When your fan only blasts on high or drops out on the lower settings, a failed 1998-2002 Mazda 626 blower motor resistor may be the cause — and the Standard Ignition HVAC Blower Motor Resistor RU-317 (also written RU317) is built to replace it. It's a direct-fit application for the 1998-2002 Mazda 626 (see the Buyer's Guide tab for full application details).
This resistor steps the voltage sent to the blower motor so the fan can run at its different speeds instead of a single setting.
If a failed resistor is the cause of your missing blower speeds, this unit replaces it.
Interchange: RU1012 · JA1168 · BR222 · GD7A61B15 · GD7A61B15A
This part cross-references / interchanges with the following part numbers:
What vehicle does the RU-317 blower motor resistor fit?
It's a direct-fit application for the 1998-2002 Mazda 626. Check the Buyer's Guide tab to confirm it matches your vehicle.
What does a blower motor resistor do?
It steps down the voltage sent to the blower motor, allowing the HVAC fan to run at its different lower speeds instead of only one setting.
What are signs this resistor may need replacing?
Common signs include losing one or more fan speeds or the blower only working on high. Have the cause diagnosed, as other components can produce similar symptoms.
What connectors does the RU-317 use?
It uses premium copper electrical connectors, which help deliver precise resistance values for improved performance and longer part life.
What numbers does the RU-317 interchange with?
It cross-references RU1012, JA1168, BR222, GD7A61B15 and GD7A61B15A.
