  2. Out-of-date software updates.
  3. Uneven air distribution.

How do you test an air blend door actuator?

Here’s how. Consult the repair manual to identify which actuators control the defrost-vent-floor “mode door” and the temperature-regulating “blend door.” Then peer under the dash and locate the suspect actuator on the heater box. Have a friend switch between modes or temperatures while you watch the actuator.

What controls the blend door actuator?

The blend door, which the actuator controls, is what diverts and controls the flow of air. There should be controlled by some plastic gears that are responsible for moving the blend door where the actuator sends the correct signals. The blend door is called a door because it really is just a flat panel of plastic.

What actuator controls the vents?

The mode door actuator controls which vent(s) air blows through. The door on this actuator has two positions: closed and open. Today, most actuators are controlled electronically. As actuators wear over time, the plastic gears inside may be stripped or broken, causing them to fail.

What does a blend door actuator do?

Blend door actuators, also called HVAC actuators, control the position of the vents that control the flow of air into your vehicle’s passenger area. The actuators are small electric motors that move the vent doors, mixing hot air with cold air to achieve the temperature that you desire.
