Blend door actuator replacement instructions please?

I would call the dealer if your mileage is correct. That is real close on warranty, they may repair it as a goodwill item.

If you do not want to do that the actuator for the drivers side (left) is right above and to the rear of the gas pedal on the side of the HVAC housing, secured with two screws.

I have done a few of the earlier ones but not a 2014. On the earlier ones you just remove the lower trim cover and stuff your hand up in to get to the part.

Reading the book on the 2014 and up looks like it may take a lot more because of the new knee airbags and reinforcements for them. Basically it says you need to remove the sound panel under the dash, then the center console, then the dash trim pad and the knee bolster on both sides. Then the knee airbags and finally you can get to the actuator.
Personally I would remove the trim and see if you can see the actuator itself. If you can and you can get to the screws you could try the old method.

Once installed you need to re-calibrate the actuators. That involves removing the HVAC control fuse for twenty seconds, then putting it back in and starting the engine and waiting a minute for the motors to re-calibrate.

Good morning,

Did you calibrate the actuator after installing it? If you did not, then you may have ruined the new one.

Are you sure it is the same actuator?

Actuator Re-calibration

Calibration Procedure

Use the following steps to perform the calibration update:

1. Install a scan tool.

2. Turn ON the ignition, with the engine OFF.

3. Select HVAC Control Module

4. Select Special Functions

5. Select recalibrate All Motors

6. Select ON, wait 60 seconds.

The fact that it is making noise tells me the new one may be damaged.

When you replace it, just follow the instructions.

Roy

No, install the actuator and then do the calibration.

Roy

Good afternoon.

It would stay on either heat or cold and would no longer be able to change.

What brand actuators did you use?

Roy

What you would need to do is remove the actuator and turn the mode door by hand until you get cold air and then leave it there.

As shown in the picture, it is under the right side of the dash.

Hello,

I does sounds like a blend door actuator is to blame which is common. Here is a guide to help you see what you are in for when doing the job and the location of the actuators in your car with the A/C system wiring diagrams and fuse locations:

It looks like there are four fuses that run the system this guide will help you check them.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Hello,

The controller must be going bad because it should shut down not allowing the blend door actuators to move. Here are the HVAC wiring diagrams and the blend door actuators location along with how to replace the controller in the diagrams below.

HVAC System Control Module Programming and Setup

Each of the following service procedures may require programming or setup procedures to be performed on the HVAC control module or HVAC actuators.

HVAC Control Module Replacement

If the HVAC manual or HVAC automatic control modules are replaced, an automatic re-calibration of all the actuators will occur. Be sure to check Service Programming System (SPS) (See: Vehicle > Programming and Relearning > Service Programming System (SPS)) for the latest calibration software. For the best re-calibration results, start and run the engine for at least one minute after installing the new module. Do not adjust any controls on the HVAC control module during the re-calibration procedure. If interrupted, improper HVAC performance may result. No additional procedures are necessary.

HVAC Control Module Reprogramming

Do not reprogram the HVAC control module unless directed by a service procedure or a service bulletin.

Reprogram HVAC Control Module-Refer to Service Programming System (SPS) (See: Vehicle > Programming and Relearning > Service Programming System (SPS)).

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

1 - Mode Actuator
2 - Air Temperature Sensor - Upper (C68)
3 - Air Temperature Actuator
4 - Recirculation Actuator
5 - Air Temperature Sensor - Lower (C68)

Yes the blend door actuator sounds like it is out here is the locations so you can see which one needs replacement. Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.
