MANY THANKS for the suggestion to remove the airbag! Did the job start to finish this afternoon. Works like new!
For anyone who's confused about these actuators, the driver side module behind the instrument cluster is the Main Panel-Floor actuator. The upper module on the passenger side is the Main Defrost actuator. The lower module on the passenger side is the Temperature Blend actuator, and the horizontal module all the way on the right is the Air Inlet actuator.
In my 2008 V6 base, the part number stamped on the original 2007-dated Defrost actuator was 6R33-19E616-BA. The new MotorCraft part is 6R3Z19E616-B. The package also says YH-1870. This is the same module that's used on the driver side for Panel-Floor. I bought mine today from a Ford dealer because of all the bad reviews on aftermarket units. Cost was about $40. It's installed now, and the clicking is gone. I opened up the old module, and two teeth were broken off one of the gears.
THANKS AGAIN!
Excellent comment, thanks!
Thank you so much sir I just replaced mine in about an hour, only thing I didn’t do was pull the fuses the removal of the air bag made all the difference in the world!!! Thank you again for the guidance! I owe ya one...
Glad to help.
The fuses made no difference?
Thank you So Much...I put this project off for 2 years ...ran across your video and now my problem is fixed
Glad to help
Fixed my mustang using this guide, thank you so much man 🤘🏽
Glad to help
Just fixed my AC with all these useful tips. Thanks!!!!!!!
Glad to help
Thank you! This fixed my car as well!!
Glad to help
Thanks for the video. For anyone preparing to do this, believe the comments about removing the airbag. I couldn’t get it done without doing so.
Glad to help
lol it was day time when he started
Thanks for this video. Funny, my 2008 defrost door actuator clicks for a few seconds when the controls are turned to Defrost, but everything works. Hot and cold temp, floor air, panel air, defrost air, everything like it should be. Guess that won't last long, huh? I can't even touch the upper actuator screw through the glove box opening. I was thinking the airbag might give access, now I know!
The clicks will result in a future failure. I recommend you replace before you have the failure. Got to love actuators.
@@chasingmustangs Yes, I replaced it a couple days ago (see below). The old actuator had two teeth broken out of one gear. One more, and it would have been dead in the water. Thanks again!
Good instructions!! Installed 3 different time because the arm relocated to the previous position. Hopefully pulling fuses will help me.
I had nightmares with this damn thing, big hands little space, upside down on floor, two years later. Round 2, here we go....
It's easier to pull a transmission than to replace the actuator. Pulling the airbag makes it a lot easier.
After removing the actuator from the passenger side the air won’t blow from the vents. The reason why I replaced it was because it made a clicking sound when moving the defrost. It’s working but it’s only working for the defrost…I installed back the old one and same thing, no air out of the vents just the defrost. Would anyone know what happened or how to solve this
having the same problem rn I think its most likely because we installed the actuator wrong but I could be wrong, did you ever figure out what it was?
Any updates?
@@itbelikethat8955updates?
damn thats a whole lotta work. lol i did not have to do all that but hey what works works!
Great video and I'll be tackling this soon. One other thing I may be doing is replacing the stock Shaker 500 with an aftermarket unit. When I have all that pulled out, would it make it any easier to replace the actuator or is that all blocked off from the stereo side?
Removing the stero will not help. The actuator is blocked by the dash support. The best thing to do is remove the airbag.
@@chasingmustangs thought that might be the case. Thank ya!
went with the airbag removal and installed everything and still having the issue with it only coming out of defrost venting. Did you test yours with the airbag out? I feel like it might not be in the track properly
@@code3ryder I reconnected the airbag bag. I the airbag not being connection should not cause you issue. I would make sure the actuator arm is connected to the vent arm.. I would also make sure the arm is moving when you change the environmental controls.
@@chasingmustangs Got her all fixed up and now she's blowing from all the vents she's supposed to. Thanks for your videos!
Hi, is it easier to see the actuator if you remove the airbag? I got my actuator out, but cannot seem to get the new one in cause I can't see to line up the arm on the actuator with the hole.
The bottom screw of the actuation is almost impossible to get to, without removing the airbag. I spent hours trying to get the new actuator installed. After removing the airbag, it took less than an hour. Also, when you remove the airbag, you should be able to see the vent arm. I found the easiest way to line everything up was to screw the actuator in half way then move the vent arm, to line up with actuator arm. These are a pain to replace. Only takes about five minutes to pull out the airbag.
I replaced the actuator with the gear on it and the arms of the other 2 actuators move when I switch from defrost to ac but defrost still won’t close . Any thoughts ? I have an 06 mustang GT
Did you do the reset instructions at the end of the video? If you don't reset the system, they will not work correctly.
Hey brother! Your video was beyond helpful so thank you! I do have a question though. I replaced the same actuator but now my car is stuck in defrost mode. Any ideas how to fix that?
And I tried two different actuators just in case I bought the wrong one. Still no luck
@@anthonyesposito4344 Did you make sure the actuator arm is connected to the vent arm? If it is connected, did you make sure the arm moved when you change environmental controls?
@@chasingmustangs thank you so much for the response! That’s exactly what the issue was. I plugged it back in but didn’t connect it to the vent Arm!
Now I have air coming out but it isn’t cold. It’s def hot when I put it in hot air but warm with cold air. I tried booking up a can of r134 with a gauge on it but the pressure gauge kept fluctuating all around for about 20 minutes and no refrigerant left the can. Had the car running and the ac on full blast. And put it on the low line with the L on the cap.
Take it to a shop to have it recharged.
Really great and detailed video however im in florida and dont need defrost and i struggled just to get the actuator off in miami sun. I took it off by removing glove compartment then reached in to pull the level manually which is like a flapper. I flipped it to the front now ac blowing through front vents. Is it the right way, Nope did it solve the issue of air blowing out front vents...absoutely. Again, i dont need defrost in florida so all is good...thanks for the video.
Where is this flapper you speak of? I’m also in Florida and just want the air blowing on me
Not easy to see behind center console actuator arm connected to door/flapper. Need to feel it out on complte removal of actuator. Worked for me and I'm no mechanic.
To remove the grey clip easily, press on the bottom back while pulling on it.
Thanks
I never plan on using the heat only possibly the AC from time to time. If left alone can this lead to major issues or just more of an annoyance?
Just an annoyance. You don't have to fix it. It amazing something so small, could be such a pain to fix.
Awesome video. If you disconnect the battery why do you need to take the fuses out for 30 seconds.? I'm just curious cuz there's no power in the car anyway.
When you pull the fuses (with the battery connected) you reset the environmental control system, which puts all the actuator at the same spot. If you don't do this and your new actuator is at the wrong position, you could break one of the vent levers or the actuator will be in the wrong position. After you pull the fuses, and turn on the AC, the system does nothing for about 5 seconds, because it is resetting all the actuators. I hope this helps.
@@chasingmustangs did you replace the upper actuator or the lower one? I could not get to the upper one without taking out the entire dashboard.
Did you replace the upper actuator or the lower one?
@@pwilki8631 I replaced the upper actuator. I could not get access to it, without removing the airbag.
@@pwilki8631 Upper
Quick question. When you say you pulled the 3rd fuse. Is it the #3 fuse(wiper power/blower motor relay) or the #6 fuse(accessory delay feeds) which is third fuse on the bottom or is it the #17 fuse? Thanks for your help.

These instructions should help you.
@@chasingmustangs Thank you!
This is the comment that saved me! Thanks Kozmos and Chasing Mustangs.
good evening!!! I have a question. I have a 2006 Ford Mustang and some air comes out of the windows and part of it is pulled towards the front glass of the car, which may be damaged?
The air vents facing the windows and the main one facing the windshield are part of the defrost vents. Sounds like it is your defrost actuator not working.
So did you pull the fuses just to install the new blend door actuator? Like when do I reinstall the single fuse you took out before you put in the new one ?
I pulled the fuses out, after I installed the new actuator. The system has to calibrate when I new actuator is installed. If this is not done, your new actuator arm may be in the wrong position.
Okay but during the video you had pulled out a single fuse when you replaced the new actuator did you put it in before starting the car or after you started the car ?
Also having trouble putting the actuator into the the vent lever I’m getting so frustrated lol
@@christianpinon3476 did you remove the airbag,
Chasing Mustangs yeah I did but I didn’t know you could move that little vent lever so I thought when I put the bolts in it was already aligned and now I think that arm move to where I can’t align it for some reason I gues that arm has moved when I plugged everything in
Which actuator do I replace if mine is not blowing any air at all but I hear ac compressor kick on I have replaced blower motor resistor
First, I would pull the fuses at the end of the video and see if it solves the problem. If it does not, use the following diagram. www.svtperformance.com/threads/a-c-blend-door-motor.916280/
If you change the temperature control from defrost to AC and the air comes out the correct vents, you know it is not the blend door actuators. That would leave you with the air circulation or defrost actuators. My guess is the defrost actuator is bad. These are the easier actuators to get to and replace. Hope this helps.
So my problem is that the defrost works, and the little tiny vents above the front vents work. But my front vents don't work at all. It sounds like the clicking is coming from behind the steering wheel. Do you think its the driver door actuator?
Sorry, I did not read this post before answer the second one you sent me. This points to the defrost actuator being broken, which is the top one on the passenger side. Especially if it is stuck on defrost. It is the actuator, I replace in this video. The noise could sound like it is coming from behind the steering wheel. You can always pull the glove both and touch the actuator before replacing. If it is pulsator and not moving, you know it is the defective one. The following link explains the location of each actuator and what they do www.svtperformance.com/threads/a-c-blend-door-motor.916280/. Hope this helps.
@@chasingmustangs Thank you thank you thank you. You just hopefully saved me a lot of trouble, I'll read up on it
I was told I had a bad blend door so I bought one online. It didn't solve the problem because there are 3 of them. So I bought 2 more of the same part and it turns out the they didn't work right because they were slightly different(the stock ones). But my AC still worked fine(when on) but when off warm air would come in the through the vents. I lived with this for about a year but now my AC only works through the defrost vents like your video shows. I wanna order 3 proper blend doors and fix it properly but don't know what to buy.
Its one of the Blend Door actuators that is bad. If you look at the following diagram, it shows the location of them. I have another video were I replace the main/blend door actuator. www.svtperformance.com/threads/a-c-blend-door-motor.916280/
Are you supposed to turn the mode on a specific setting before replacing the actuator? Such as no air, defrost, etc? I used to have cold air and it went out by only blowing through the defrost. I replaced the actuator and it now blows normal again but it’s not as cold nor strong. The reason I feel like it’s not the compressor is because I turn on the heater and it as well doesn’t blow as hot and when I switch it to defrost it blows cold. Help please
Because you disconnect the battery during actuator replacement, the mode doesn't mater. You just need to do the actuator reset instructions when done. I would double check the compressor fuse, that AC compressor is connected to the harness. If they are good, then you need to check the driver side template door actuator behind the cluster.
Chasing Mustangs but don’t I have to disconnect the battery since I have to remove the airbag to get to the actuator? Thanks for the help sir!
@@imfanzz1 yes, you have to disconnect the battery to remove the airbag.
Chasing Mustangs oh sorry I read that again and it made sense lol was confused
@@imfanzz1 no problem, best of luck. I also have a video shower driver side actuator replacement, if you need it.
Hi thanks for the video. I've installed a new actuator on the driver's side and the top actuator on the passenger's side since they were both clicking. I am getting ready to connect the battery but don't want to mess this up. You mentioned turning off environmental controls and pulling fuses 10 and 12. Do I need to pull any more fuses since I've replaced 2 of 4 actuators? Also just confirming the steps. 1. connect battery 2. pull fuses. 3. turn off controls for 30 seconds. 4. replace fuses. Does that sound right? Thanks again. Also had a trick for replacing the actuator on the drivers side without taking the car apart. I removed the easy bolt then broke out the old actuator made it so much easier to then remove the pain top bolt and replace with new actuator. I just used a screwdriver handle to prop up the air duct. It wasn't easy but easier than removing the dash.
You need to pull the fuses, so you don't ruin one of your actuators. Resting the actuators makes sure they are all in the same position. if you don't do this, you could break an actuator or one of the door arms. The steps you listed above are correct. Just make sure you pull the fuses for at least 1 minute, before putting them back in. Hope this helps.
i’m having the same problem with mine but i’m not sure which actuator motor it is. Because i know there is also one behind the instrument panel. There’s no clicking sound but the main vents don’t work only the floor vents and the defroster. Do you know which one it is?
www.svtperformance.com/threads/a-c-blend-door-motor.916280/
Sounds like defrost actuator, the one a replace in the video.
Defrost actuator is what I replaced. The manual I used called it a blend door actuator for defrost.
When you pulled fuse 10 and 12 was that before or after connecting the battery?
After
What about the key in the ignition? When and what do you do with that?
have no defrost, every thing else works, I need to replace the top-pass side like you did right??
Yes, the hardest one unfortunately.
@@chasingmustangs thanks
@@chasingmustangs did you pull the fuses and left the key on/off ???pulled then turn on for 30 sec or???????
Pull the fuses with the car/ignition off. Just make sure the battery is connected.
@@chasingmustangs thank you very much for the help sir.!!!!
Not sure what you changed but it did not look like the temp blend door. The mode door is on the other side and that is what controls were the air blows from.
I changed the name of the video after I learned it was the temperature defrost actuator.
Ok so i changed this one and the one behind the instrument cluster. But It still did not fix it. SO i tried taking the actuator out all together and i tried moving the arm manually and the air still did not switch from the defrost vents. I did this with both actuators and nothing. What do you think the issue could be if it is not the actuators
You moved the vent arms on both sides manually and still going out the defrost? If you are not hearing the thumb sound when manually moving the arms, then the arm is broken inside the dash.
@@chasingmustangsso it's ok to move the vent arms manually?
@mikeprice8307 yes, as long as you remove the actuator for the vent testing.
I've looked everywhere to find an install procedure for the defrost actuator on my 2014. I can see it from the glove compartment hole at the very top of the dash, much like this video. I had multiple people tell me that it is behind the guage cluster, but I don't think that is true for the '14. I can see the air inlet (recirc) actuator on the blower motor, the temp blend actuator on the left wall by the blower motor, the floor vent actuator right next to the temp blend on the left wall, and this defrost actuator at the very top of the wall, above the temp blend and floor vent actuators. I have a base model with manual controls. I believe the one they are talking about is for '05-'12, but am not sure because of the mixed answers.
Does anybody happen to know if this procedure is the same on '14 Mustangs?
Ok, the true actuator for the defrost is on the passenger side. There is an actuator on the drivers side behind the cluster. The drivers side one seldom goes bad and will not cause the vent to be stuck on defrost. Check it this diagram. www.svtperformance.com/threads/a-c-blend-door-motor.916280/. I have never owned a 2010 to 2014 Mustang, so I don't know if the instructions are different. The part number says it works for 05 to 14 Mustangs, so I am assuming the instructions are the same.
@@chasingmustangs Wow, I have been searching for this EXACT writeup for weeks. Thank you so much!!
You don't have to pull any fuses, when you hook the battery back up it will automatically recalibrate the actuators.
So my manual (not an official Ford manual), says you have to pull the fuses with the battery connected, to it put the new actuators in the correct alignment state. American Muscles web site says the same thing. If your have a Ford manual the states something different, please share it. I own a limited set of Ford shop manuals, because of the cost.
@@chasingmustangs I've done around a hundred of those,that's my manual.And what do you think you are doing when u pulled the fuse,nothing different and undoing the battery .
Old video, but have you replaced the driver side one behind the gauges? Seems to be no guide out there for that one.
There is a vid available
th-cam.com/video/j7C3JH9LOhY/w-d-xo.html
I have. Helps to have better tools and wedge a piece of wood or something between the vent duct to raise it up some.
my key fob won’t unlock my doors or lock or trunk will the actuator be the issue?
Did you change the battery? If you did and still have issues, then you need to link your car to your fob.
Water got inside my car under my glove box and radio everything works fine just can’t lock doors with fob and headlights stay on once I turn my key
Which actuator would i replace. If AC comes out colder on passenger side vents? My compressor is new, and freon levels are good as well. Anyone have a clue?
Check this link out, it explains all the actuators and what they do. www.svtperformance.com/threads/a-c-blend-door-motor.916280/
I did this and it still did not work. Do you think it is the one behind the instrument cluster?
Yes, there is one behind the instrument cluster and it will cause similar issues. I have a video on replacing the actuator behind the cluster.
What about if the defrost won’t activate at all? Everything on mine works except for the defrost and I definitely hear the infamous clicking
The actuator is stuck in the non defrost position. These instructions will work to replace the actuator.
Like A San said. I did not have to do all that to replace that actuator. Took me 15 minutes to replace. Its accessible via the glove box alone.
when i turn mine to defrost it blows air into the footwell? front vents and foot vents work fine but defrost is broken what actuator is that?
This points to the defrost actuator, which is the one replaced in this video. When the defrost actuator breaks, you are either stuck with everything coming out the defrost vents or everything coming out the front vendors. Attached is a link showing all the actuators and what they do www.svtperformance.com/threads/a-c-blend-door-motor.916280/.
Help me fix my mustang as well! Highly appreciated!!!
Glad to help
I'm sorry but why did you remove the defrost? Do you think I could try this with my defrost still working?
I would only use these instructions if you car is stuck on defrost. There is 5 actuators in the car that could be bad, depending on the issue you are having.
Yeah it's stuck on defrost currently but is there any way I can be able to do this with my defrost still working?
Thank you tho sir I greatly appreciate you for responding and sorry for being annoying I juss don't much about this but I'm trying to fix it cause I'ma sell my car
@@swaggyc4436 Sorry, the only way to fix this is to replace the actuator.
@@chasingmustangs thank you I appreciate your reply after all these years man
Good video but removing the top cover where the airbag is unnecessary in my opinion cuz it still doesn't give you the right angle or view.
I have short fat arms and had to remove the Airbag to get the access I need.
I'm so done with this fix, I've installed 1 actuator and it broke even after pulling the fuses. Got a replacement and same thing, installed, connected the battery, pulled the fuses, waited, reinstalled fuses, waited, turned car to ON (engine off), waited, tested the AC and still clicking. I'm afraid if I turn it to defrost it'll get stuck again. Got any tips? 08 mustang v6.
Try this, connect the actuator and don't install it. Mark the actuator arm location and then perform the reset instructions. If it is at a different location, then reinstall it. I have seen the need to perform the reset before installing the actuator in the car.
@@chasingmustangs i dont understand what you mean
What I am saying is connect the new actuator to the wire harness, but don't install. Perform the reset instructions and the install it. I have seen actuator go bad because they are not aligned for the install. They will break. Doing the reset before installation will prevent it.
@@chasingmustangs ah, so if its not aligned after rest open it up and turn the gears to straighten the arm?
@@sks220 a reset before installing should bring the arm on the actuator into spec.
Just replaced mine but it’s still only coming out of the defrost
Did you pull the fuses like I said in the video?
Dude the auto place I took to said they didnt know which of the 3 actuators it was and that they had to test all 3 and wanted 200 bucks just for that. I have this same problem thanks
What can break if you don't do the reset part by removing fuses 10 and 12?
You could brake the vent arm of the actuator you installed.
@@chasingmustangs Is that the arm of the actuator or the thing that plugs onto?
@@chasingmustangs How hard is that to fix if it happens?

How many actuators does a mustang have? I have a 2005 mustang

Chasing Mustangs but how many actuators does a mustang have? Lol
@@osvaldo_9653 LOL, tired and missed what you are asking. There are four actuators, specifics in a Mustang 2005-2009.
Chasing Mustangs fuck... the passenger and driver side air vents aren’t working right only the defrost vent is where the air is coming out so i need 2 actuators?
Chasing Mustangs i was only able to find 2 actuators on the passenger side and only 1 on the driver side i cant fins the 4th one... any advice?
I don’t have fuse 12 what do I do
Do you have a 2010-2014 Mustang? If you do I believe it is 15 and 26.
I already replaced it an set everything back and it works so much better than before and finally no more clicking
Damn, you're in a big rush!
My bastardly ACTUATOR was top right...Unless you take out Pass. seat, glove compartment door, Air Bag, cut excess plastic to into bolt closest to you and you have hands of a 6 year old and weigh 135 lb.DO NOT attempt this freaking replacement of the noisy actuator..I almost set my car on fire I was so pissed!
So after replacing the top actuator pulled the fuses and it’s still stuck in defrost. 🤷🏽♂️ only thing is I’m not exactly sure if I lined up the arm in the right place. Good god I can’t really see anything up there just going by feel.
Did you pull the air bag to help you see? The actuator has to be in the middle of the arm to work. I have fat hands and cant make it work without pulling airbags.
My ac is stuck on my feet in a 2006 mustang
Sounds like the main actuator is not working. See my video about replacing the drivers side actuator.
