- There are other videos on how to remove the EATC unit, and describing the replacement but I didn't see one that showed how to repair the actual unit clearly, when I mention silicone in the video, I mean dielectric grease. These are the parts you need from McMaster Carr or Amazon links below:

You need to replace all 4- O-Rings in the EATC unit, and after the repair and re installation, the car must be running to test functionality (It needs vacuum assist to operate).
You're the only one who did it this way, you didn't take the entire housing, spring, spacer etc. apart. Many newer videos they are doing those extra steps that don't need to be done.
I just did this repair on a 2004 Crown Vic. First I examined the vacuum lines in the engine compartment. Next I tested the vacuum reserve tank on the drivers side inner fender. It was fine. I then inspected all of the vacuum lines under the dash as well as I could see them. All looked fine. I ordered the O-rings from McMaster-Carr for approximately $3.00 for a bag of 25. They came in two (2) days.I took my time taking the dash piece off and removing the unit so nothing broke.The repair went just as described.Less than two (2) hours start to finish. The system is now functioning perfectly.Very glad I did this.
The O-ring part # is: 9396K12
I don't create to many videos, but this was definitely needed. I'm so glad it is helping a lot of people !
Took a few videos and troubleshooting to find out why it was defaulting to defrost and floor vents. Great video, went and checked to see if the unit had vacuum and the accumulator door. Both were fine and the heat and ac function worked great. Cant safely drive in the south with ac fogging up the windshield. The Hvac unit is in good working order and the car is a 2006 crown vic with 66k miles. Just got my O-Rings in and will be replacing them ASAP. Again thanks for the video.
This fixed my HVAC Controls. 2006 Crown Victoria LX. Blend door actuator was working and the HVAC controls had a vacuum.
Thank you for your additional troubleshooting experiences. I'm glad your issue is resolved !
Hey thanks! Just did this to my 2005 Grand Marquis and it worked. Wasn't switching from vents to anything else, now it seems to work. I can hear that good old school clunking when I change to the floor vents, and MAX AC is back in full force.
Mark,
Sweet ! Glad it worked for you also, how much did it cost to replace the components ? How much time was involved ? Just for everyone else's curiosity.
Big thanks, worked for me too on my 2006 Grand Marquis. I noticed that you are asking about other ways to get the rings. Well I saw this on a Saturday and needed immediate satisfaction so I went to my local auto parts store and they had the 007 o-rings (that's what they're called). I paid about .80 cents each and $1.50 for silicone grease. $6.00 at the end of the day and I'm so please. AC and heat blowing where it should now.
So glad it helped you out.
Hi kingpcb... I just wanted to say THANK YOU. After watching your video a few times, waiting about a month or two, I got the courage to try this and it worked ! The A/C and vents work properly now. You just saved me from having to give Ford about a thousand bucks. If you were nearby, I would buy you lunch. Thanks for taking the time and effort to post this video.
Thank you for the comment, I'm so glad it also helped you !
Thanks for the extra indepth. Have had 3 Grand Marquis since 1996 and somewhat the home mechanic on them. This issue : well spent lots of time on troubleshooting and still same issue and then came across your video. Ordered the O-rings : installed in about 30 minutes: works great. appreciate the help. Issue is solved. was dreading dropping the console to replace the panel door motor but had found out it was working well. Eventually pointed to the control module and well the orings were weathered out, one really dry and crumbly. I do go to fordforums and put my two cents in when i can. again thanks. you have inspired me to make a video of something I may know that others dont.
123skyvision , part number please , links in the description open to same product
I will look for the package in the garage and see what it might say on it. May get back to you later on today or tomorrow.

ARTHUR LEAL thank you very much for the effort dear , i am in saudi arabia and need to fix my eatc , the part number 9396K12 doesnt show any result over amazon
The original O-rings that came with the car are outdated. They are made of silicone, and silicone isn't the strongest O -Ring. They are prone to tearing and failing prematurely. My advice is, buy the one's that are "nitrile." I know that Harbor Frieght carries a set of 205 pcs. They are all different sizes, but comes with the size you'll need for your panther platform. It's the F1014x labeled in the box. The item number is 67644. .
The box will say, "HNBR O-Ring Assortment. HNBR stands for "hydrogenated nitrile butadiene rubber," which is far superior to silicone and withstanding extreme temps. So when you look for new O-Rings, don't buy the silicone ones, get the HNBR ones.
If you don't live in an area where there is a Harbor Frieght then check out their website.
Great video-Just did mine this weekend. 2004 Grand Marquis. I did not have an issue but just being proactive. 2 O-rings questionable and 2 were so so. Changed all 4 to silicone . Should be good for another 11 years, lol!
Smh. Proactive
thanks a lot. this solved my problem perfectly. works great.
did my 04 crown vic last week. took about 45 minutes. 100 ct. silicone 007 0 rings on ebay for 6.50 shipped.
Just do a search for "EATC REPAIR" on youtube. Several videos there about testing and the problem.
Thanks for the video! Does a parts store offer the o-rings without waiting on Amazon? Advance auto, auto zone, oriellys ?
I wonder why other videos show people removing that entire assembly bracket. It looks like all you did was remove the plunger without removing the plunger housing . Is that correct?
I believe that is correct, I had to remove part of the housing. There are probably different variations of manufacture. The idea is to access and replace the O-rings, inspect the plastic tubing to ensure no other possible vacuum leaks. Just use your creativity, view all the videos you can and once you get it out I'm sure you'll determine what is best in your application.
Did this turned out black plastic vacuum line broken at firewall
Any broken vacuum lines or a leak in the system could contribute to this problem, this video does not take this into account. This video only repairs decayed O-rings at the head unit HVAC control.
I tried this on my 2003 Harley Truck and now it only defaults to defrost, before it would work through vent. I used o-rings but not the brand you had could it make a difference? On the ends of the coils what is the purpose of the rubber? On mine it was more like a sponge type material. For the time being I rigged the vacuum to bypass the controller so I can get flow through the vents.
The ends of the coils is a spongy material as you describe, I'm not sure of the purpose exactly but I believe it is a venting type material which allows the pressure to equalize ? If you didn't use o-rings that were the correct size, it could make a difference as vacuum would escape around the o-rings. Did you also use the lubricant grease ? I would recommend double checking the sizing of the o-rings and perhaps purchase the ones I recommended.

I've replaced the o rings in my 2008 Merc Marquis and it works for a while and then the same problem occurs. I got the 007 silicone O rings 100 pack but can't figure out why it only last for a day or so. Last time I did the fix I just keep the air condition running cause I know after I turn it off and get in my car later and try to run the AC it's back to hot air and Floor and Defrost. any advice or help would be very much appreciated. Thanks!
Make sure you are using the Dielectric grease to lubricate the O-rings, and if that does not work you could have another vacuum leak. Check all the vacuum lines you can access.
nice video..
but, what are the problems that require this perform?
because my air conditioner has problem with the pathway of the air !!
sometimes it change to floor , DEF or may doesn`t pass !!
See this video for more information for the problems this may fix:This fixed a problem where the blend door was not operating correctly (not changing to floor / defrost or panel vents).Basically the o-rings are bad, and leak so that there is not enough vacuum to operate the blend door.@watch?v=hAqE-oYnvlQ
My question is; Does the silicone grease still allow the solenoids to function At -20F. ?
The operating temperature for the silicone grease is -65 to 400 F images-na.ssl-images-amazon.com/images/I/61oevGGtMdS.pdf
I did this on my 2008 crown vic and it's still blowing cold air on my windshield. Is there anything else it could be?
Search for "EATC REPAIR" on youtube, there you may find steps to run a diagnostic which will give you a code to search. If there is no code, you may have done the repair wrong or one of the o-rings may have split.
I can't even get to the o-rings because my EATC module isn't bolted down, it looks like it's spot welded. Any idea on what to do?
Eric Castro Do you mean the EATC module is welded to the car, and not screwed in? All the videos I have looked at on youtube are screwed in. I don't know your particular application, it may be different or you are looking at the wrong unit?
kingpcb the assembly itself. Sorry, I confused the parts. Whereas yours has 8mm screws holding it down, mine has been spot welded in place. If that clarifies it any.
Eric Castro Perhaps you could drill out the welds, repair the EATC unit, then put some retainer clips (sometimes called "speed clips" in that would be placed instead of the weld?
It's up to you, that is my opinion. If your not comfortable doing that, time to call a professional.
kingpcb that's actually what I was thinking about. Luckily, I work at an auto shop, so I can have my coworkers look at it. Thanks for the help though.
drill welds..bracket comes off from around plastic. hooks..
A 1995 Explorer and they just don't slide out. They are spot welded together and are to hard to repair. Don't try to fix it if you don't have a drill press and lots of time!
now will this solve the problem of not being able to turn the a/c off at all
+Chris Taylor There is a diagnostic you can run on the EATC unit . For me, this fixed the problem with the blower doors / direction of airflow.
See this link for a video someone else did for the diagnostic (I have not verified if this will diagnose your issue).

amazon is out of these orings, now where will I find the right ones?
amzn.to/2l8aguk
ok cool thank you
Does this work on Ford rangers
You'll have to pull the unit, if it has vacuum lines connected then most likely it could have the same issue.
Find and dandy but you didn't show if it works in the vehicle once you put everything back together.
That's called Trust, I hope you can learn to use it.
Orings have to be silicone?
Silicone O-rings are more durable, and the additional cost is not really prohibitive. Silicone O-rings have a higher Tg rating (hot / cold endurance). If you want to do it again in a few years, get cheaper O-rings.
anybody know if it matters that I damaged the foam on the ends?
I'm not sure what the function of the foam is, I would imagine it is a type of filter for the vacuum. Depending on the damage you incurred, perhaps you could find a similar material and replace it.
I also destroyed my foam when I did this and I used the foam off of a foam paint brush and just cut it down to the right size... I have no idea if it's actually functioning inside there or if it's just causing a whole bunch of damage but it seems to be working for now so that is tomorrow's problem LOL
where can i buy the silicoln o'rings?
Phuk You please see the original notes. there are links to the products there

I went to the junk yard found a 1998 Lincoln continental broke it down the O-rings look new so I took the whole actuator , put it with my 2006 grand marquis eatc and some dieletric grease an it work ! 98 Lincoln system is not the same as the grand marquis but the actuator are so hope this help someone !!!
It's an o-ring, not a grommet
You found the easter egg ! Congrats !
