What does air inlet actuator do?
The AC actuator moves air distribution doors to two or more positions to direct air flow for heating and A/C vents. The motors can move the doors into many different positions, or just two. There are three methods used in the automotive industry to operate the HVAC doors or flaps for distributing cars in cabin air.
How to remove the actuator for valve repair?
Removing the Actuator for Valve Repair To remove the actuator: 1- Using the proper tools, remove the mounting hardware bolts from both the top (Actuator) and bottom (Valve) sides of the mounting bracket. 2- Carefully remove the actuator and place it in a clean area.
How does the intake valve actuation system work?
The Intake Valve Actuation system (IVA) uses pressurized engine oil to delay the closing of the intake valves. The system is controlled by the Engine Control Module (ECM). The system contains the following components: Check Valve (53) – Pressurized engine oil flows to a rail inside the valve cover base.
Where are the actuators located on a cat engine?
The ECM sends a signal to the coil in order to fully open the spool. The oil is released into the space underneath the valve cover and the rail pressure is reduced. Actuator (54) – The actuators are located under the valve covers. Pressurized engine oil flows from the rail to each actuator.
How does an idle air control valve work?
The IACV valve is operated by a step motor. This motor has winding phases and is actuated by the output signals of ECM. Each time the IACV opens or closes to change air quantity, the ECM sends a pulse signal to the motor. A certain voltage signal is issued so that the valve remains at a particular opening.
Where can I find a replacement actuator for my car?
These repairs can take a little longer because more parts need to be removed to gain access to the actuator. You can use a repair resource such as Mitchell1, a paper manual found on Amazon or a resource like Google images to locate the particular area in which the actuator needs to be replacement.
Where is the temperature actuator on an Impala?
Look up near the top of the glove box door, you will see how to drop the glovebox all the way. There are two of the actuators they are easily accessible from the glove box. I believe the temperature svtuator is on the left, and the inlet actuator is further back on the right side.

Do you need to replace the blend door actuator?
Hmmm replace now, do it again in 4 years….. or disconnect them and somehow “lock” the doors. Sure is an irratating thing to deal with.:gaah: Click to expand… The only one you would want to lock toils be the the air inlet door to the outside air setting. Two of them control your temperature settings, and you wouldn’t want to do that.
