2001 - 2004 Toyota Tacoma Replace Air Mix Servo, Blend Door Actuator, AC Noise Fix, No Heat Fix

This video shows the removal and bench testing of the "Air Mix Servomotor" for the '01 to '04 Toyota Tacoma, part #87106-04010. Sometimes this motor fails, and causes a rapid "clicking" sound when you turn the climate control knobs.
This also causes your AC to "get stuck" and won't allow you to change to the heater mode. It is easy to remove and replace, and sometimes you can even repair it and save money.
Thanks for watching. Good luck with your repair!

Does the motor control the knob with the blue, red and white colors? or does it control the knob with the icons for face and feet air, windshield air, etc? my problem is no outside air coming in, only warm air. I want to be sure i am removing the right part/motor. Thank you

[@SDsailor7]

Is it ok to spray the "needles"/contacts with electrical solvent ie. Deoxit? or should we just leave them alone? Thank you

[@SDsailor7]

When you do the installation of the motor does it matter in what position you install it? or not? Sorry to ask so many questions it might not even be my problem since your description says "AC Noise fix" and "No heat fix" but i like to learn in case this ever happens to me. My problem like i said before is no outside air ventilation, only getting warm air and when i turn on the AC i do get AC but not enough cooling due to the heating air. I did check the hot water valve that is connected on the back of the fire wall and it is working {it opens and closes} Thank you

[@SDsailor7]

You should be a teacher! great presentation!

[@L35inColorado]

@@SDsailor7 This is a good question, and I don't know the answer -- I would first try "reusing" the existing grease, for example moving it back if is has piled up in one area; the reason for that approach is simply because I'm not sure what kind of grease would be appropriate for that connection (the original grease almost looks like some kind of dielectric in consistency). Deoxit would clean it up, but would it lubricate it? I'm not sure, but you can try and then just check resistance in a few combinations from the record to the terminals.

This servo you are showing is for the vent door/ flap control and not for cold & heat mixing i.e. climate control. The servo that controls the cool & hot air mixture is a different unit and for my 2004 Landcruiser Sahara is located behind the the blower & vent door ducting. To get to this particular servo you need to remove the entire dash board & i do mean everything. It is a nightmare of a job. Allocate a day and half but it is the only way to get the climate control to operate properly.

[@L35inColorado]

No, this video is for the '01 Tacoma's HVAC system, not the '04 Landcruiser, and the servo shown is the Air Mix servo on the '01 Tacoma. It is a well-known fault on the Tacoma. Your Landcruiser will have different servos, and servos in different locations because the HVAC system on the Landcruiser is much more complicated than the Tacoma's, and the system has automatic features that the Tacoma doesn't have, which means more motors and more complication. I haven't done that job on a Landcruiser, but I have done servo jobs Mercedes (MB's have very complicated HVAC systems) and I know what you mean -- MB puts those servos deep inside the dash and you must remove the entire dash to service them. It is a huge pain, like you said. From what you're saying, it sounds like Toyota did the same thing for the Landcruiser, which is really a hassle! I'm sorry that you're having that problem with your Landcruiser. Those servo's are cheap, either ($$). Good luck with your repair -- I know how you feel : )

Control arm*

[@L35inColorado]

I don't have a motor on hand, but I remember having to press the little white tab that holds the arm keyed to the shaft, and then used a flat pry under the arm to give it a little encouragement to move up. You don't have to remove the arm to open the case and inspect/replace parts inside -- you can leave it in place and just pop open the black tabs on the sides of the case. You do have to be VERY careful, though, for all the parts because as you know they are plastic, and they are also old, so things get brittle. Good luck!

The confusion on the warm/cool is due to the double arrow. they are showing that to go to warm the arrow goes from bottom to top CW, and to switch to cool it will go down CC. understand ??

[@L35inColorado]

I'm sorry I missed your comment - I made this video a couple years ago, so I reviewed that part at 03:15 upon seeing your comment: I'm still not clear with why the FSM labeled the second image with the double-ended arrow and used the perforated outline of the arm at the lower/8 o'clock position on that second image. I'm not clear with what the second image is trying to communicate, but, yes - as you said, the clockwise movement ends at the "warm" position at about 11 o'clock, and the counterclockwise movement ends at the "cool" position at about 8 o'clock. When I sent the motor out in the "cool" position (8 o'clock/lower position), the installer was able to slip it into place on an lever that was set at the cool position. Thanks for watching!

I am having trouble with this.

If I remember correctly, you can see it without removing anything - you have to look under the dash on the passenger side, towards the center. There might be a trim piece to pop out on some models, but there wasn't a trim piece on the '01 Tacoma. I hope that helps - good luck!

Are both 87106-04010 and 87106-04020 compatible with 2003 4Runner? Seems like they should be the same as in a Tacoma. Hearing the clicking from the driver’s side, but dont want to risk replacing one part to find out that the other has also died.

[@L35inColorado]

I would call your dealer and verify, but no, according to what is shown on the Toyota parts site, neither of those parts fit the '03 4Runner. Instead, the HVAC motors are shown as part number 87106-35150 for the lower motor (by the blower motor), shown here: parts.toyota.com/p/Toyota_2003_4Runner/HVAC-Blend-Door-Lower-DAMPER-DAMPERFOR-BLOWER/63395818/8710635150.html And then 87106-35120 as the upper motor, shown here: parts.toyota.com/p/Toyota_2003_4Runner/HVAC-Air-Inlet-Door-Actuator/63472602/8710635120.html If the motors themselves are the same, you can swap out the arms, as mentioned in the video.

[@L35inColorado]

I'm sorry that's happening -- it is possible that if the blend motor motor is going out, and if that's the case, then the motor won't close the door all the way when you want full-blast AC (and the motor does sometimes make a weird noise when it starts failing, but typically its a clicking noise). You can check that our yourself by looking at the motor from the passenger side, as shown in the video: put your setting and full HOT, and look at the position of the white arm. Then change it to full COLD (or better yet, have someone else change it while you're looking at it, or use your cell phone camera), and take note if the arm moves. You might also want to check out this video about the blower motor making sounds and how to fix that (just note in that video, when he says "condenser", he means "evaporator"): kzbin.info/www/bejne/q5nFpKupj76Sa8U If you don't see anything wrong with the blend door motor or blower, then I would take it back to the AC mechanic. Good luck!

Oh man, that's too bad -- if you have junkyards in your area, see if there are any '98 to '04 Tacomas. Alternatively, do you think you can glue or epoxy the arm to the shaft?

[@apeterson239]

I gorilla glued it but I didn’t really need to. It was a snug fit on the new actuator. I just replaced the part by following your video and now my truck has heat again! Thank you!

@@apeterson239 Good job, nice!

[@SDsailor7]

My motor is not clicking it is just not doing anything no movement at all. So the water heater valve wont open.

[@TRD_Cueto]

Did you really have to remove all those dash components for this? I need to swap mine in my 02 Tacoma

[@L35inColorado]

No, the Tacoma shown at the beginning was in a junkyard, and that is why so many dash parts were missing. You can look under the passenger side dash and see the motor without removing much, perhaps just one panel (maybe not even that). I hope that helps - good luck!

[@huntercolpitts4532]

Did you have to remove the whole dash just to get to this or can you drop the glove box and get to it?

[@L35inColorado]

I'm sorry I missed your comment -- no, you don't have to remove the entire dash -- just look under from the passenger footwell area, and you'll see it. You just need a flashlight and small screwdriver. You can see it in this video here: kzbin.info/www/bejne/fniYnGewpc-ojbM Good luck!

[@SDsailor7]

So is this blend door actuator controling the heater water valve cable? Anyone know? Thank you

[@bujabal76]

What do these codes mean B1443 & B1447 for Toyota Land Cruiser Prado

[@SDsailor7]

Is there a relay or a fuse that controls that actuator motor? Anyone know? Thank you.

@L35 in Colorado i just recently changes this part out and got my heat back, but now im having issues with my a/c and heat switching on and off on its own? Any ideas? Thanks in advance.

[@L35inColorado]

I'm sorry that's happening -- if you mean that the air is suddenly blowing, then not blowing, it might be the blower motor: www.tacomaforum.com/threads/2001-taco-air-blower-shuts-off-on.9541/ I had a blower motor issue in another Toyota where a squirrel had hid nuts in the blower motor! It would run, then stop (jammed by the nuts!), then run: in that case, cleaning the blower motor fixed the problem. Here's another youtuber's video on the issues: kzbin.info/www/bejne/q5nFpKupj76Sa8U I hope that helps -- good luck! : )

[@cesarcardenasfigueroa1862]

@@L35inColorado thanks for the reply! I meant like il be driving and the a/c will be on and then suddenly it switches to heat on it own, usually i just turn the a/c/heat knob back and forth and then it’ll reset and eventually it’ll do it again.

[@GotchaplumberGotchahvac]

Is the thing that will make clicking noise & not allow heat to blow?

[@L35inColorado]

Yes, some people describe a clicking noise when this motor fails. I hope that helps!

[@GotchaplumberGotchahvac]

Mine sounds like a clicking.

[@jron5113]

link to buy just the motor?

[@charliekelley7213]

Would you think this servo motor is the problem if when using a/c and all of a sudden the heat comes on hence the heater valve is opened and once I turn temp selector to hot and back to cold it closes the heater valve and it gets cold again?

[@L35inColorado]

Possibly, but I would suspect the door itself for that issue, or a linkage between the door and the motor, or the HVAC control module before the motor itself. (Please understand that the following is speculation because I don't have this truck to look at.) Perhaps you can check it like this: set the AC as you do, then get under the passenger side dash (or use your phone/mirror) and watch the linkage by the arm and wait till the problem occurs and the heat comes on. There are two possible observations: either the arm moves when the problem occurs, or the arm does not move. If the arm on the motor moves when the problem occurs, then I would think that the problem is either a bad command from the control unit (telling the motor to turn to heat when it shouldn't), or the motor internally has an issue. In the second case (internal motor issues), then replacing the motor would fix the issue, but not for the first case. If the arm doesn't move, then I would eliminate the motor as a cause and instead consider possibly a loose linkage between the arm and the door. It might be that the door is skipping off a linkage intermittently, causing the AC airflow to close the door, or that the door hinge points have an issue. In that case then when you reset the knob, the motor moves the arm and catches the linkage for the door again (temporarily). Again, please understand that this is all speculation because I do not have this truck to look at and I don't even have an HVAC diagram for it, but rather I'm speculating based on what I've seen on other like-year Toyotas with non-cable drive HVAC systems such as the Tacoma. I hope this helps! Good luck!

[@charliekelley7213]

@@L35inColorado Thanks, it is one of those things that might only happen a couple of times a week or maybe even a month between times. I have taken the cable off the heater valve a while back but as you know cold temps are right around the corner.

[@charliekelley7213]

I am going to assume that since the motor is opening the heater valve via the cable that it is either the motor or the temp control

[@bulldograu1]

Charlie, did you ever solve this problem? My 2002 4runner does the exact same thing. But it does it every few minutes while driving. Not fun having to turn it to hot on 110 degree day and then back to cold hoping it will reset itself ha thanks for the update.

[@ivanlm743]

My 2002 Tacoma is doing the exact same thing, replaced the part in the video with no results

[@JeffreyWillis800]

Is it same area for the 2005 Highlander? Need to replace mine or pay mechanic $520.

[@L35inColorado]

I don't know about the Highlander: in some models, the motor is much harder to reach, which might explain the price for that job (the motor itself is also expensive). Perhaps check out the toyotanation.com forum for your Highlander. Good luck!
