Blend Door Actuator Replacement | Nissan Titan, Armada, Infinity QX56

The blend door actuator is a common failure point that causes an awful clicking noise under the dash on multiple vehicles including 2004-2009 Nissan Quest, 2004-2015 Nissan Titan, 2007-2015 Nissan Armada, and 2004-2010 Infiniti QX56. In this video, I demonstrate how to replace the AC/heater direction control actuator on my 2007 Nissan Titan SE. Your particular vehicle may be slightly different, depending on model/trim package.

Dorman replacement actuator:

Great camera work and clear instructions. I appreciate the time and effort you put into this repair. Your video for this repair is second to none.

Thank you very much for the perfect video. I appreciate the production value. Pro tip for anyone that reads this, when you install the replacement actuator and the gear is not clocked around to accept it. You can take apart the old actuator, remove the gear and use it like a tool to to move the dampers into the correct place so the splines match up and the new actuator just slides right on.

Man I'm glad I found your channel this morning. My 2006 did this until the AT went out and I got a used 2012 that does the same thing. I figured out how to fix my ignition tune key issue and this today.

Excellent video. Great instructions. Great camera work. Thanks for making this. My truck has exactly the same issue with the “clicking” and no Defrost. A+++

[alexlui]

I appreciate the video! How come other folks are having such a hard time doing this job compared to you? One guy even took the whole dash apart!

[BroncoMan]

Amazing Video and Instruction. Thank you for that. I was able to gather proper tools and replace and test within 30 mins on my 2007 Titan and only removed the kick panel. I was able to work around the module/amp that is mounted on the 2 brackets. No more tapping ! Thanks again.

AYYY YOOOO!!!! I am having the same issue with my armada. Before I landed on your video I had replaced the blower motor to no success. After trouble shooting and figuring what the name of the part that was going out I came accross your video. I am ordering my part tonight cna't wait to follow this video again. My kids call my truck the "hot box" cause the ac isn't blowing out of the front faacing vents. Only if they knew what "hot box" truly meant.

Dude!! I can't believe I did it myself. Thanks for showing everything needed. The only things I did differently than you was removing the drivers seat (I'm on the larger side and it was easier for me to lay on my back and look up at it) and my replacement actuator included an extra key I was able to use for clocking the actuator plate.
Thanks again, bruh.

I used this to guide me through the replacement of this actuator on my 2005 Titan. Mine is a base model that doesn't have the high-end stereo. I bought the new actuator off eBay for about $16. I was not as lucky as you in this video and knocked loose the cam plate that controls the two levers. But it only took a few minutes to get it back into its proper place after removing the cover over it. What I especially liked about your video is that you explained which functions this particular actuator controls. I looked at some exploded diagrams of the Titan's HVAC system and it has like 5 actuators on it. My Titan would only blow air out into the footwells, not out the dash vents like you need in the summertime.

Ahhh the things you find on YouTube. I just ordered the replacement actuator. I was actually doing research for speaker replacement when I came upon your video. It will be nice to have the blend door working properly again. Nice video!

Having now completed this job successfully, I first want to say thanks. Excellent video! You saved my rear. And second, how in the name of God did you get a camera and light in that awkward tiny space???!!!

[mekanicgames]

Very good video. Excellent camera angles. That isn't typical of repair help videos.

[donaldcurrence]

Hooray, best video I've seen on this, just replaced mine using this video. Finally noise is gone after putting up with it for years. Thanks!

[Dynamike]

This helped me do the job, took about 1 hour and a lot of bad words. For the 7 mm screw right by the bracket you'll need a wrench as opposed to a ratchet. A ratchet won't fit between that mount and the screw. Also, big thing to add. Your new actuator will come with the teeth "opening" pointing up, but the actuator you take off your vehicle may have the teeth in a different orientation (pointing left or right), you'll need to take your new actuator apart so that the "opening" is in the exact same position as the one you're replacing or it won't fit. It's very easy to take apart and just turn the teeth to where it should be to match your old actuator.

Best video on this replacement I have seen.

[mrjones]

Great video. Bout time someone gets straight to the point. Thanks

[glendathomas]

Great instructions and camera work, the clicking noise is on both sides, so I'm replacing them one at a time, thanks.

[alanj.bernal]

Very nice well done video, my dad and I been looking for hours and this just saved us, Appreciate the great job you made!

I bought a used 2005 Titan and noticed this "clicking" noise on day one. After watching many Youtube videos and having mechanical skills I decided to replace the actuator on the drivers side. The part I ordered was not the same as the one I took out. The replacement part had the "gear' type drive and my actuator had a "double D" type drive. I did hours of research on this and through a friend got connected to the local Nissan dealers parts department where I found out that some early 2005 production units have the "double D" type drive. The "double D" type drive can be found from various sources, , ,

Excellent video and excellent explanation.., ... that's exactly what my Armada needs.
