If you are searching for a BMW 525i blower resistor, BMW 535i blower resistor, or BMW M5 HVAC blower motor resistor, this part number provides a direct reference point.

This part cross-references OE number 64118391699 for the same application.

What It Helps Fix

• Blower motor works only on one speed
• Fan speeds are intermittent or inconsistent
• Cabin airflow is weak because speed control is failing
• HVAC fan does not respond to the control switch as expected
• Loss of proper heater and A/C blower operation in BMW E34 models

Installation Notes

Verify the vehicle year, model, and HVAC configuration before installation. Compare the original resistor and connector style to SW11232C, and inspect the blower motor and related wiring for heat damage or corrosion before replacing the part. For best results, confirm fitment against the listed BMW applications: 1988 BMW 535i and 535is; 1989-1995 BMW 525i; 1989-1993 BMW 535i; 1991-1993 BMW M5; 1993 BMW 525iT; 1994-1995 BMW 530i; and 1994-1995 BMW 540i.
