Standard Ignition HVAC Blower Motor Resistor P/N:RU-58
Keep every heater and A/C fan speed under control with the Standard Ignition 1995-1998 Mazda Protege blower motor resistor (P/N RU-333). This blower motor resistor drops in as a direct-fit replacement for the 1995-1998 Mazda Protege, controlling the current sent to the HVAC blower motor so you can select the range of fan speeds on your heater and air conditioning. When a resistor fails, one or more fan settings often stop working while others still run.
Precise resistance values: premium copper electrical connectors are used for more accurate resistance, which improves resistor performance and offers a longer part life.
Seamless HVAC integration: the research and design process leads to smooth integration with the vehicle's HVAC system.
Variable-speed control: designed to restore A/C and heater blower motor variable-speed control, helping optimize HVAC performance and passenger comfort.
Tested for reliability: undergoes extensive testing to help ensure correct performance in a range of conditions.
Specifically designed for Mazda applications. If a failed blower motor resistor is the cause of your missing fan speeds, this replaces it; diagnose the cause before ordering.
Interchange: RU1021 · JA1157 · BR231 · BC1M61B15 · BC5E61B15
This part cross-references / interchanges with the following part numbers:
Does this fit my 1995-1998 Mazda Protege?
Yes. The Standard Ignition RU-333 is a direct-fit replacement for the 1995-1998 Mazda Protege. See the "Vehicles it fits" section to confirm your exact vehicle.
What does a blower motor resistor do?
It controls the current sent to the HVAC blower motor, allowing you to select the different fan speeds for the heater and air conditioning.
Why are only some of my fan speeds working?
A failed blower motor resistor commonly leaves one or more fan settings inoperative while others still work. If the resistor is the cause, this part replaces it.
What other part numbers does the RU-333 replace?
It interchanges with RU1021, JA1157, BR231, BC1M61B15 and BC5E61B15.
What are the connectors made of?
It uses premium copper electrical connectors for more precise resistance values, which improves performance and offers a longer part life.
