How Many Blend Door Actuator In Chevrolet Silverado – Complete Guide

Do you know? The blend door actuator controls the temperature plus airflow of the Chevy HVAC program. They greatly influence your vehicle, but have you checked how many blend door actuators are in the Chevrolet Silverado 2023 model? 

It depends on the model of your vehicle, but typically, you’ll have two blend door actuators located under the dash on your driver’s side and above the foot panel on the passenger’s side. Also, the previous models used to have one actuator.

Before everything, you need to know the location of the door to ensure how many doors are available in your model Chevy Silverado. Therefore, the entire article will reveal more notable facts about door actuators, like their jobs, issues, or how you should fix them. However, let’s explore what’s cooking inside the content.

Purpose of Blend Door Actuator in Chevrolet Silverado

Not everyone knows the job of a door actuator, so we would like to introduce the system first. Generally, the actuator controls everything, including how much air blend door moves through the car’s heater core.

Your air mix or blend door moves between clean air and recirculated modes, cold and warm airflow, and defrost modes, similar to an electric motor that operates forward and reverses the motion. Unfortunately, if this system fails, the AC system will be triggered, and either heated or cool air become blocked.

How Does a Blend Door Work on a Chevy Silverado?

Do you know how the actuator on your Chevy operates? Typically, the actuator or electric motor maintains your air door rotational job. However, check below to know how this system works.

• The actuator is an HVAC motor that operates with your vehicle’s temperature sensors to run the environment control program.
• The door actuator location will get a signal when sending any cool or hot air.
• After receiving the indication and the signal, actuators will determine if the air passes through the floor vent, mid-vent, or defrosters.

How many Blend Door Actuators are in Chevrolet Silverado?

We noticed some automobiles included multiple climate system controls to let the back seat passenger maintain the environment. The latest Chevrolet Silverado features double temperature control and dual door actuators.

As previously stated, one actuator will manage the temperature in your front seats, whereas the other is developed with the rear passengers in mind. Older vehicles, such as the Chevrolet Silverado 2007 and 2008 models, only used to have 1 door actuator. However, models made in 2009 and beyond have two actuators.

What’s the Chevy Silverado Blend Door Actuator Location?

Depending on the model, the actuator for your car can be located differently. We don’t want to go back to check the past models, but the common previous models we use should come into the business. So we took the query “Where is the blend door actuator on a 2007 Chevy Silverado?” as an example.

The phasing door actuators are generally far away from the heater core and an evaporator than the door actuator. Or, if you’re interested in knowing where the 2011 Chevy Silverado blend door actuator is located, It will be beneath the glove box, close to the passenger’s foot.

What Happens When Blend Door Actuator Fails?

Commonly, failure of the blend actuator can cause difficulties with the HVAC program. What upset the Chevy is that the temperature control system will not function, leading to improper heating and cooling, odd noises, and poor air circulation. Aside from this, we have more symptoms that say a bad door actuator requires fixing.

Silverado Chevy Blend Door Problems – Troubleshooting Actuator

The actuator on your Chevrolet will not always keep everything in proper control. So your car will have difficulties, like overheating, light issues, airflow trouble, etc. Though it’s complex to identify when your blend actuator is in trouble, you can check the common signs we are sharing below to understand whether replacement or repair is required.

• Inappropriate temperature
• Various or Two temperature
• Uncontrollable Temp
• Light clicking sound under the dashboard
• Knocking noise
• Inaccurate airflow
• The blend door will not close and open
• A burning smell.

Inappropriate Temperature

The first sign is a faulty actuator, delivering the wrong temperature data. You can verify its functioning by blowing warm air from the heater or cool air from the AC unit. In any case, if you prefer hot air and it comes out cold or cool air, and it comes out hot, the blend door actuation system is damaged.

Various or Two Temperature

Another sign that a defective actuator is present involves two or more temperatures. A car with a dual temperature control system where the climate control is not operating indicates that the actuator needs to be repaired.

Climate control may become jammed on one side and operate on the other. This will result in your vehicle being cool on one side and warm or hot on the other.

Uncontrollable Temp

A faulty blend door actuator becomes more challenging to regulate. For example, if you set the temperature to warm, the automobile cannot lock the door while remaining cool.

Light Clicking Sound

A clicking noise from the dashboard is another symptom of a broken door actuator. It continuously indicates that your vehicle’s HVAC system is in threat. Additionally, the clicking noise becomes more observable when you switch on the air conditioning unit or intensify when you turn it on to set the temperature.

Knocking Noise

If you turn on your Silverado’s AC system, you will likely experience squeaky noises from the dashboard. Not only squeaky or clicking noises but also the knocking noise will come from the dashboard. Whenever you hear such noises, it signals you to check your blend door actuator.

Inaccurate Airflow

When the blend door actuator fails, the blend door will move back and forth. This allows the air to be misdirected, resulting in uneven airflow in the cabinet. The accident happened as a result of a broken door actuator.

Blend Door Will Not Close And Open

Sometimes, the blend door behaves like a broken system, refusing to open or close. As a result, you must ensure that all of the connections to the blend door actuation are securely attached. If you still encounter a problem, verify your blend door actuation system.

A Burning Smell

Chevy Silverado’s faulty actuator often produces a burning smell when you turn on the AC. It commonly occurs when the actuator is burning and needs your attention immediately.

Silverado Blend Door Actuator Test

Finding troubles can be ensured by doing some tests. If you discover problems within your Chevy vehicle, for instance, a lack of heat, try the following tests.

• Typically, a blend door actuation system utilizes electrical motors to adjust the temperature and airflow. Therefore, disconnect the battery first to avoid any risk of short circuits or accidents.
• A burnt blend actuator generally causes the heater to blow cold air. Recalibration is a way to shift the temperature effectively.
• You must ensure that the heater hoses are warm. Most likely, replacing or repairing the actuator will resolve your issue. The only item required to install a new actuator is a ¼” driver socket set plus screwdrivers. Check the manual for the troubleshooting concept just before you begin.
• Another important test is determining which actuator controls the blend door. Also, look beneath the dashboard for the actuator, which is close to the heating box.
• While checking the actuator, you will need the assistance of a second person to change the temperature and mode settings. The fact that the actuator is not moving indicates an issue with the blend actuator.
