Cross-reference part numbers for the same application include 4P1769 and RU617.
Common Symptoms This Part Can Address
- Blower fan works only on certain speed settings
- Cabin airflow is stuck on one speed
- HVAC fan stops responding to the control switch
- Intermittent heater or A/C blower operation
- Poor cabin comfort due to inconsistent air delivery
Installation Notes
Confirm the vehicle is equipped with air conditioning and automatic temperature controls before ordering. Match the connector style, pole count, and physical dimensions to the original resistor. On BMW 318i, 318is, 323i, 323is, 328i, 328is, and M3 models, access is typically through the HVAC housing area, so inspect the blower motor and related wiring for heat damage or corrosion during replacement.
Quality Assurance
VEMO replacement parts are cataloged for OE-style fitment and application matching. Verify the part number V20-79-0004 against the original component and vehicle equipment details before installation.
