Description

Help bring back full fan-speed control for your BMW's heater and air conditioning with the Standard Ignition HVAC Blower Motor Resistor RU-818. This blower motor resistor steps down voltage to the blower motor so the fan runs at each of its lower settings; if a failed resistor is why your fan only works on high (or drops certain speeds), this drops in as a direct-fit replacement for many BMW models, including the 2016-2018 BMW M2, 2015-2018 BMW M3 and 2015-2020 BMW M4 — see the "Vehicles it fits" section for the full list.

Premium copper connectors: deliver more precise resistance values for improved resistor performance and longer part life.
Kanthal D resistor wire: provides greater flexibility, durability and tensile strength in the wiring on higher-watt resistors.
Designed to restore variable speed control: helps return A/C and heater blower variable speed operation to help optimize HVAC performance and passenger comfort.
BMW-specific design: engineered for seamless integration with the vehicle's HVAC system and extensively tested for correct performance.

Buyer's Q&A

Frequently Asked Questions

What does the RU-818 blower motor resistor do?

It regulates voltage to the HVAC blower motor so the fan can run at its lower speed settings, giving you variable heater and A/C airflow control.

My blower only works on the highest setting. Is this the fix?

A failed resistor can cause the loss of the lower fan speeds. If the resistor is the cause, replacing it with the RU-818 restores those speeds; diagnose first, as wiring or the switch can also be at fault.

Does this fit my BMW?

It is a direct-fit replacement for many BMW models, among them the 2016-2018 BMW M2, 2015-2018 BMW M3 and 2015-2020 BMW M4. Check the "Vehicles it fits" section to confirm your exact year and model.

What numbers does the RU-818 interchange with?

It cross-references 64119231742, 64119270254, 64119276112, RU1507, JA1967 and BR718.

What is the resistor wire made from?

It uses Kanthal D resistor wire, which offers greater flexibility, durability and tensile strength for the higher-watt resistor circuits.
