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.

Hi Random,
Does your Titan have the Rockford Fosgate stereo?
For mine, I'm just not getting the clear line of sight that you have in your video behind the bracket. And that is because there is a module directly behind the bracket. Unless I'm missing something. Thanks for posting the video.
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!
Very nice well done video, my dad and I been looking for hours and this just saved us, Appreciate the great job you made!
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.
Great video
So many bad videos out there I was surprised to see a good one and had to comment
Is this for "mode door" actuator or "blend door" actuator?
your system does not take into account the stereo amp that can be mounted behind the BCM. Not a great help. For instance you mention removing a panel if you drop the screws but do not tell how. Don't assume somebody watching the video knows anything.
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, , ,
I believe that's mode door actuator
It looks like you removed something to get in there, what was it? How is a full grown human supposed to get in there?
I have a 2008 Titan w/automatic a/c that doesn’t blow and clicks for 25 sec. when pushing the buttons that show horizontal air flow to the body. I checked the only fuse that I could see that would be for the a/c – 10 amp HVAC – and it look like it was ok. Are there 2 separate problems or does one effect the other?
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.
That's not the "blend door" actuator that's the "mode door" actuator just in case you don't know the difference.
I believe you changed the 'MODE door' actuator, not the blend door.
Very good video. Excellent camera angles. That isn't typical of repair help videos.
Oh yeah, I got the Rockford Fosgate in a 04 LE will be watching dash removel video's. thanks for the video all the same.
Excellent video and excellent explanation..,… that's exactly what my Armada needs.
I’m working on a 06 QX56 with the amplifier option so the only way I’ve been able to get it out is to remove the amplifier in order to get to the top screw.
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!
I'm having an issue where I've replaced the actuator and now the ticking is gone but the climate control isn't working. No air temp changes. Having trouble finding this specific issue, most I find is heat related not both.
That knocking noise can get annoying,but I have that knocking noise coming from the passenger side as well.
Well my blend door actuator to control the temp. Is on the upper passenger side on top of the hvac box near the firewall. Scraped up the arms to get to it. But I got it. Can only imagine what the shop would of charged
Mode door or blend door? Ur turning the mode door knob
Muchas gracias por tu vídeo fue muy fácil con tus intrusiones gracias (thanks for you video )
One minute you called it the mode actuator and then you called it a blend door actuator?
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.
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.
I have the exact same setup as you. I attempted this fix, but the white plastic piece the actuator fits into fell out of position as I tried to fit the actuator in it. Any tips on how to get that back into proper position? Great video- best one on YouTube for this fix.
Oh this was a pain to get changed out. Dropped screws in between the carpet and the flooring multiple times and the white plastic piece that the actuator plugs into at the gear fell out. So just a time consuming thing after time consuming thing. I know now that doing mechanic work is 55% mechanical knowledge and 45% contortionist.
My titan has warm air coming through vents when I have the "hot/cold" dial set all the way to cold, this is without the AC on.. when I turn AC on its cold.. could this be issue with actuator in middle of dash?
