What is this part and why does it matter?

This actuator motor controls the position of the heater’s air flaps, which set temperature and airflow direction.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Air temperature isn’t controlled correctly
  • Unusual clicking or crunching noise when changing climate settings
  • A flap gets stuck in one position

Installation information

Mounts to the heater housing, wired into the connector, often followed by calibration.

Frequently asked questions

Often worn gears inside this specific motor, which is trying to turn the flap but is skipping teeth.
