BMW 1 / 3 / 4 Series HVAC Air Conditioning System Blend Door Actuator Servo Motor | Part No. 64119321034 | E & F Chassis - E8X E9X E6X F3X

If your BMW’s air conditioning is blowing weakly, only cooling on one side, or sending air through the wrong vents (like the windshield when you select face-level), it’s likely a failing HVAC air door actuator motor.

Over time, the factory servo motor can burn out, preventing the internal air flaps from opening and closing correctly. This disrupts airflow direction and causes inconsistent cooling — a common issue on many BMW models.

Replace your faulty unit with this direct-fit OEM-style replacement, designed to restore proper airflow throughout the cabin. No coding or programming required — just remove the old motor and install this one.

Key Benefits:

• Restores air direction control (vents blow correctly when selected)
• Fixes cool air blowing on one side only
• Improves airflow strength and overall HVAC system performance
• Direct plug-and-play fitment — installs like factory part
• No coding or calibration needed
