How does the blend door actuator work?

To blow heat into the cabin, the blower motor sends air through the heater core and on through the dash vents. But when heat is not desired, the blend door actuators direct that airflow away from the heater core. There are also actuators to direct air to the dash vents, floor vents and windshield vents depending which setting is selected.

What are the symptoms related to a bad blend door actuator?

The symptoms of a bad blend door actuator include a lack of heat or air conditioning, or failure of air to blow through some or all of the vents. The actuator motors may also make a noise if they've failed, but this isn't always the case.

The technician will test each vent position and temperature range. The amount of air and its temperature will be noted for each setting. If there's no change between settings, the blend doors are a strong possibility. When these components are suspected, testing the circuit and observing them while they're working are the only ways to test them. The electrical wires or vacuum lines will be inspected to ensure the proper amount of power is being delivered. From there, the parts can be bench tested to pin down the problem.

RepairPal recommendations for blend door actuator issues

We don't recommend using DIY universal blend door correction kits, as these kits involve cutting into the HVAC ducts and replacing OEM components with generic components.
