I just went through that process. damn!! i replaced the entire unit. i used the drilled hole technique. i learned that the brace through which the holes is drilled is bolted to the transmission tunnel. it was tough getting my assembly out so i unbolted that brace and bent it out slightly so i could get the assembly back in. its helped. i also unbolted my front seat and pushed it back. that helps tremendously!! the arm positions are (from the bottom arm going to top) down, up, down, up. rubber bands help. once everything is lined up it literally pops in. you'll know it when it does. regarding the bottom servo position....other videos have indicated there's an arrow and holes that have to be aligned. mine did not want to work that way. i had the dealer calibrate mine just to be sure it was in the correct place. let it line up where it wanted to line up. it worked. you can look at the gears and see there's a gap on the black gear on bottom servo. i think that marks the point at which it registers itself. keep in mind the servos work in independently of one another. I know way more about tundra blend door actuators than i ever intended.
Thanks for the video, about to embark on this on my '07 Tundra, and was just quoted 7 hours labor at the local shop, and they were reading off the book where as they remove the entire dash and steering column. $900 in labor alone, so I thin I will break out the tools and a sweat rag now that I see it can be done without removing everything but the carpet!
Just curious what code everyone got before replacing “Damper Servo Sub-Assembly”. I am getting B1446 on my 2010 Toyota Sequoia. I think this is the part I need to replace. Any thoughts ?
Great video, I am assuming this is what I need to replace on my 2014. My driver's side heat doesn't blow hot in "sync" mode, just warm. The passenger side is very hot, but the driver's is luke warm. Does that sound like a symptom this part would fix?
@@timzauto Wow, thanks for the super fast reply..and for the advice on how to set the vents and mode before taking off :) I hope that saves some headaches.
I’m trying to do this on a 2013 Toyota Sequoia, but I can’t figure out how to remove that long black trim piece. You sorta skipped over that process in your video
Do you have to initialize this ? I don't know anything about these but watched another video about initializing these of they may not work at all after installed.
No codes,and one of the actuators was bad,so I replaced the whole unit on this model,some you just replace one actuator at a time but on these you do the double ones with the servo kit,the symptoms of course would be blend or mode not working .Do you have a Toyota not working right?
@@timzauto I do. My 2010 Sequoia has a 45 second delay before heat/ac controls come on. It has the B1445 (Cool Air Bypass Damper Control (Passenger Side)) code by scan tool. Other than the 45 second delay, everything seems to be working ok. Not sure if swapping out this same module would address the code as it appears it has for others with similar servo related codes. All the gears appear aligned and moving properly so not sure what the code is all about.
@@jefffitzgerald2024 The cool air bypass servo motor sends pulse signals, This activates the motor based on the signals to move the cool air bypass servo motor to any position.If you have a delay it is not getting a signal at that time,I would replace the servo unit.
@@timzauto Thank you! Just to confirm, you are suggesting to replace the same unit you replaced in this video. I'm asking because my code references passenger side.
Yes I know,it's a bitch,make sure you move the middle gear towards you,it takes a couple of tries.Also make sure u have the new unit plugged in and set the ac on all the way cool on and straight on face vent.
I have a 15 sienna, in recirculate it pulls in outside air. The passenger side does not regulate. When it is moist I see fog from the defrost area. And it goes in and out like the door is floating. Dealer said nothing is wrong. 🙄. Let me know. Looking for parts.
@@timzauto for the record, i spent away more time than that but then i didn't know what the hell i was doing. i also took out a lot more stuff than you did. now i know. i hope never to have to do it again!!
@@shcaskey yes, it was fun, but all u really have to do is drill that one hole I showed you and line up everything, if u have the climate settings on a/c and face vents before u take it off it will be calibrated like that, thanks for watching.

All I can say is good luck,because getting it back on all lined up will test your patience,lol.

Yes that is for that code,if you're not having issues with your HVAC system don't worry about it,if it is having issues replace it,have fun,lol.

I didn’t remove it,I drilled a hole in that metal piece,u don’t have to remove it.
Do you have to initialize this ? I don't know anything about these but watched another video about initializing these of they may not work at all after installed.
No,they will re-calibrate on their own,or you can disconnect the neg battery and they will.
Great video
What code(s) did you read out and/or how was it diagnosed that this part needed replacing? Thanks!

@@jefffitzgerald2024 Yes,it's for the passenger side,the part is on the drivers side,lol.
I can’t get the middle gear to Aline. The one with the whole that has to match and opinions?

You need to change the part that I did in the video.It controls all three things.
@@timzauto Thanks Will do.!
How long did the whole job take you? I have been quoted that it will take 10 hours.
Between 2 and 3 hours for everything,mainly because it's very cramped under there and u have to line them up just right.
