Detailed Product Information

URO part number 64116923204 is an HVAC blower motor resistor designed for BMW climate control systems that have lost one or more fan speeds or stopped responding correctly. This resistor is used in BMW X3 and X5 applications, along with select BMW 325Ci, 330Ci, M3, 525i, 530i, 540i, and M5 models. It also cross-references Standard Ignition RU-652 for the same application.

By regulating blower motor voltage, this component helps return consistent cabin airflow for defrost, heat, and air conditioning operation. The OE-style design supports straightforward replacement in vehicles that use the original connector and mounting layout.

Common Symptoms It Can Address

• Blower motor works only on certain fan speeds
• No airflow from the vents at some speed settings
• Intermittent HVAC fan operation
• Reduced heating or air conditioning output
• Burned or heat-damaged blower resistor failure

Installation Notes

Verify the vehicle’s HVAC system type before ordering, especially on BMW 325Ci, 330Ci, and M3 applications that require Valeo HVAC systems. Confirm the part number 64116923204 against the original resistor and match the connector style before installation. Access is typically through the HVAC housing area, so inspect the blower motor connector and surrounding wiring for heat damage or corrosion during replacement.

Quality Assurance

This URO blower motor resistor is factory tested for proper performance and backed by a 24 Month Unlimited Mileage Warranty.
