So, I reviewed the images for the knee booster, and I do not know if I am seeing what you are seeing, but if I remove this knee booster will it allow me to get into the housing where the door actuator connects? I read somewhere on the net that the door actuator connects to another part that is inside this housing. That is what I can't seem to get to, and I need to connect the door actuator to it. Here is also a video that I came across with the issue that I am having: https://youtu.be/sG2JrEmvJ9A

My dilemma is not wanting to tear the housing apart the way this guy did in his video to get to the blend door actuator connected to that part that is inside that housing.
I really appreciate your experience and knowledge in helping me with this.

Okay, went back through your information. From your description it sounds like the actual blend door has failed. They are nothing but a plastic flap with a pivot pin molded on two corners. One of the pivots goes into a hole in the case and the actuator connects to it, the other sets into a blind hole on the opposite side of the air passage. I suspect you have the same issue as the video, the door pivot broke off. If it dropped into the case there is no real easy way to get to it to fish it out and get it back into place. If it broke as I suspect getting it back into place will not really help as it would not stay in place and work.
The options are to cut the housing open, replace the door and glue the housing back together or remove the entire dash to remove the case and replace the door. Not really any other way. If you cut it open you do not need to worry so much about strength, you can always glue a section of plastic over the cut area as a reinforcement.

Yes! Thanks for reviewing over the information. I am relieved now that I know what I have to do. I may just have to go the route the way the guy in the YouTube did. Thank you all for your help! And thank you, Steve, for reviewing over the information and keeping me from going back and forth.

Cheers! Bonnie

One thing you could do to make sure of what you have would be to buy one of the cheap bore cameras that hook to a smart phone and use the hole in the case to see what is wrong inside. You could see what is in the case and if you opt for cutting it would let you plan the lines better.

I have a 2012 camero RS that has cold air coming out of the passenger side and hot air coming out of the driver side. What’s the problem?

That would be the same actuator and blend door covered in the posting above. Either the actuator or door has failed.

Please help. I know this is 1 year later but the same problems still exist in the Gen5's.
I completed the entire task of replacing the broken blend door. Now, I'm confused. How do you remount the blend door motor to the new blend door making sure that it's time/synchronized correctly?
I've read so many different methods online and I really don't want to replace another blend door within a week due to not having it synchronized correctly. Any and all advise would be greatly appreciated right now.

Thank you in advance

If you mean you replaced the actuator and door and got it all together, the actuator will self calibrate it's location. If you don't have a high level scan tool you can follow this procedure.

Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.
1. Place the ignition switch to the OFF position.
2. Install the HVAC actuator.
3. Connect all previously disconnected components.

4. Remove the HVAC control module fuse for a minimum of 30 s.
5. Install the HVAC control module fuse.

6. Turn the ignition ON.
7. Wait 60 s for the HVAC control module to self-calibrate.

It will move all of the actuators to full open/closed and then set them to the points that match the settings.
