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.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
