If a failed resistor is why your heater and A/C fan only works on one setting, the Standard Ignition RU-510 blower motor resistor for the 2000 Volvo S40 is designed to bring variable fan speeds back. It is a direct-fit replacement for the 2000 Volvo S40; see the Buyer's Guide tab for engine details. The resistor regulates the power that reaches the blower motor, which lets the HVAC controls select different fan speeds for heating and cooling.

  • Copper electrical connectors: Premium copper connectors are used to achieve more precise resistance values. They are intended to improve resistor performance and support a longer part life.
  • Designed for HVAC integration: Standard Ignition's research and design process aims for seamless integration with the vehicle's HVAC system.
  • Variable speed control: Designed to restore variable speed control to the A/C and heater blower motor, helping HVAC performance and passenger comfort.
  • Extensively tested: Undergoes extensive testing at Standard Ignition's facility to confirm correct performance across operating conditions.

Signs an HVAC blower motor resistor may need replacing include a blower that runs only on its highest setting, lower fan speeds that no longer work, or a fan that does not respond to the speed control. A faulty switch, blower motor, or wiring connector can cause similar symptoms, so diagnose the cause before you replace the part.

Frequently Asked Questions

Will the Standard Ignition RU-510 fit my 2000 Volvo S40?

Yes. The RU-510 is listed for the 2000 Volvo S40. Check the Buyer's Guide tab for engine details before ordering.

What does a blower motor resistor do?

It regulates the power reaching the blower motor, so the heater and A/C controls can select different fan speeds.

What are the signs the resistor may need replacing?

Common signs are a blower that runs only on high, or one or more fan speeds that stop working. A bad switch, motor, or wiring connector can cause the same symptoms, so diagnose the cause first.

What part numbers does the RU-510 interchange with?

It cross-references RU1203, JA1701, BR413, 30872797, 30873431, 30875042 and 308750420.

Why does the RU-510 use copper connectors?

Standard Ignition uses premium copper electrical connectors for more precise resistance values. They are intended to improve resistor performance and support a longer part life.
