Common Symptoms

In addition to improper temperature and/or air flow output from the dash vents, you may also hear a clicking noise from behind the dashboard.

Best Practices

Depending on the vehicle the replacement of the Blend Door Actuator will require the removal of the dashboard. This adds considerable labor costs, increasing the overall price of this repair. 

Part Explanation

In a vehicles heating and cooling system, the blend door actuators help control the air temperature from the vents, as well as direct air to selected vents.

How Part Works

To blow heat into the cabin, the heater blower motor blows air through the heater core and through the dash vents. When heat is not desired, the blend door actuators direct airflow away from the heater core. There are also actuators to direct air to the dash vents, floor vents, and windshield vents as desired by the occupants.


Blend door actuator motors may become noisy when they are no longer able to move the blend doors. They also may be silent if the actuator motor has failed completely. Vacuum type actuators should never make any noise. When the blend door actuator has failed, certain functions of the air conditioner or heater may cease to function. This may be failure to change airflow to a separate vent, or failure to change air temperature from the vents.

Failure Urgency

Driving with blend door actuator failure may not be comfortable, but it will not harm the vehicle. The air conditioning ducts are not part of any other system, and will not change vehicle performance.

Replacement Interval

Blend door actuators fail frequently on some vehicles, but not in others. Therefore, the rate of failure will depend on the vehicle make, model, and year.
