Standard Ignition HVAC Blower Motor Resistor P/N:RU-729

$128.99

Description

If the heater or A/C fan in your BMW has lost some of its speeds, the Standard Ignition RU-729 front Blower Motor Resistor is designed to bring back variable blower speed control. It is a direct-fit replacement for the listed applications, including the 2006-2011 BMW 323I, 2007-2013 BMW 328I, 2007-2013 BMW 335I, 2007-2017 BMW X5 and 2011-2018 BMW X3.

Copper electrical connectors: Premium copper connectors are used for more precise resistance values, which helps resistor performance and is intended to extend part life.
Built for BMW: Specifically designed for BMW applications. Standard's research and design process targets seamless 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 in-house: Goes through extensive testing at Standard's facility to verify correct performance across operating conditions.

The resistor controls blower motor speed at each fan setting. Signs it may need replacing include a fan that runs only on its highest setting, missing fan speeds, or a blower that won't run on certain settings. Other faults can cause similar symptoms, so diagnose the cause first. If a failed resistor is the cause, this unit replaces it.

Fitment: 2006-2011 BMW 323I, 2006 BMW 325I, 2006 BMW 325XI, 2006-2007 BMW 330I, 2006 BMW 330XI, 2007-2013 BMW 328I, 2007-2008 BMW 328XI, 2007-2013 BMW 335I, 2007-2008 BMW 335XI, 2007-2017 BMW X5, 2008-2013 BMW 128I, 2008-2013 BMW 135I, 2008-2013 BMW M3, 2008-2015 BMW X6, 2009-2013 BMW 328I XDRIVE, 2009-2011 BMW 335D, 2009-2012 BMW 335I XDRIVE, 2009-2016 BMW Z4, 2010-2015 BMW X1, 2011 BMW 1 SERIES M, 2011-2013 BMW 335IS, 2011-2018 BMW X3, 2013 BMW 135IS, 2015-2018 BMW X4, 2018 BMW X2.

Frequently Asked Questions

What does an HVAC blower motor resistor do?

It controls the speed of the blower motor that moves air through the heater and A/C vents. That lets the fan run at the different settings you select.

What are signs the blower motor resistor may need replacing?

Common signs include a fan that runs only on high, missing fan speeds, or no blower on some settings. Other faults can cause similar symptoms, so diagnose before replacing.

Which vehicles does the RU-729 fit?

It fits 25 BMW applications, including the 2007-2013 BMW 328I, 2008-2015 BMW X6 and 2009-2016 BMW Z4. See the Buyer's Guide tab for the full list and engine details.

Why does the RU-729 use copper connectors?

Standard uses premium copper electrical connectors to achieve more precise resistance values. This helps resistor performance and part life.
