- PRESS and HOLD the DOWN arrow for 10-15 seconds to re-initialize the system.
- Once complete, the switch should display “027” (Figure 5).
- Once both sets of control boxes are reset, remove the programable hand switch and install the switch that came with your system.
Thus, Which actuator controls the front 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.
Additionally Does a blend door actuator need to be calibrated? Your blend doors should be calibrated, especially after having work done on them.
Which actuator controls the defrost? What does the actuator do? The blend door actuator decides whether the air is going to come through the mid-vent, floor vents, and control defrost, and so on. Some cars have a dual blend door actuator that enables the driver to control the climate in different time zones.
Where is the blend door actuator located? Where is the blend door actuator located? Remove the glove box and under-dash trim panels to find and replace the door actuator.
How do I test my blend door actuator?
Is blend door open or closed for heat?
There are just flaps inside the ducts, called blend doors, operated by vacuum motors, that open and close to allow heat or stop heat from coming through the vents into the passenger compartment.
How many actuators does a car have?
Typically, vehicles have 3 or 4 actuators. Vehicles with rear controlled HVAC will often have additional actuators to control the auxiliary unit, bringing the total per vehicle to as many as 6. DID YOU KNOW?
What controls the blend door actuator?
Most vehicles use an electric motor actuator to control the position of the blend door (though, some use a mechanical cable instead). Depending on the system design, there may be just one blend door actuator or multiple blend doors and actuators.
How do I know if my blend door is stuck?
How much does it cost to replace blend door actuator?

Is blend door actuator and mode door actuator the same?
The blend door actuator is typically located closer to the heater core and evaporator than the mode door. Mode Door Actuator: The mode door actuator controls which vent(s) air blows through. The door on this actuator has two positions: closed and open.
What happens when a blend door actuator goes bad?
The most common symptom of the A/C Actuator going bad or when the Blend Door is stuck is when you feel inconsistent air flow coming in. The desired air you want whether it be hot or cold, is being diverted incorrectly, so you are not getting a consistent temperature out of the A/C system.
