Standard Ignition HVAC Blower Motor Resistor P/N:RU-235
Standard Ignition HVAC Blower Motor Resistor P/N:RU-235
$47.99

Keep your heater and A/C fan stepping through its speeds with the Standard Ignition Blower Motor Resistor RU-235, a direct-fit Mazda B2200 blower motor resistor for 1987-1993 models that also fits the 1987-1993 Mazda B2600 and 1986-1987 Mazda B2000.

The resistor sits in the blower circuit and varies the current sent to the blower motor, which gives the lower fan settings their slower speeds. When it fails, the blower may run only on high or skip some settings entirely. These are signs this part may need replacing, but a faulty switch or wiring can cause the same symptoms, so diagnose the circuit first.

  • Copper electrical connectors: Standard Ignition uses premium copper connectors, designed to deliver more precise resistance values for better resistor performance and a longer part life.
  • HVAC integration: Standard Ignition's research and design process aims for seamless integration with the vehicle's HVAC system.
  • Variable speed control: If a failed resistor is behind your fan-speed problem, this unit is designed to restore variable speed control of the A/C and heater blower motor. It helps support HVAC performance and passenger comfort.
  • Mazda-specific design: This resistor is designed specifically for Mazda applications. Standard Ignition puts it through extensive testing at its facility to check for correct performance.

Frequently Asked Questions

Will the RU-235 fit my 1987-1993 Mazda B2200?

It is listed as a direct-fit replacement for the 1987-1993 Mazda B2200. Check the Buyer's Guide tab to confirm the engine details for your vehicle.

What does an HVAC blower motor resistor do?

It varies the current reaching the blower motor so the heater and A/C fan can run at different speeds. When the resistor fails, some or all of the lower speed settings may stop working.

What are signs the blower motor resistor may need replacing?

Common signs include a blower that runs only on its highest setting or skips some speeds. A faulty switch or wiring can cause similar symptoms, so diagnose the circuit before replacing parts.

What sets this Standard Ignition resistor apart?

Standard Ignition uses premium copper electrical connectors, designed for more precise resistance values. It also tests the part extensively at its facility to check for correct performance.

Which part numbers does the RU-235 replace?

It cross-references RU935, BMRA240, BR145, 1468105860 and UB9361B15.
