Chrysler Pacifica - Updated Active Grille Shutter Wiring
ฝัง
- เผยแพร่เมื่อ 5 ก.พ. 2025
- In this video I stay late at the shop to look at a '18 Chrysler Pacifica for one of my used car dealers. They installed a new active grille shutter (AGS) and claim it doesn't work. So they installed a new factory harness and it still doesn't work! Let's have a look and see what we find.
-Enjoy!

This is one of only two TH-cam channels where I hit the like button before I watch the video.
They're all good.
The other is Pine Hollow Diagnostics. The two best car diagnostic/ repair channels on YT.
Me too !
Like videos made
Lol me too
Its 8:45pm in Australia and im outside watching this with my fiance. The first thing out of her mouth is "Theres your problem lady!". You know you found the right girl when she can quote Eric while reading her book.
Anyways, Eric, thanks for not only being informative, entertaining and just funny as all heck. Youve provided me with countless hours of teaching but more importantly.....you give everyone confidence.
Confidence in that if you can do it.....we can do it. Dont be afraid when a light comes on. Educate yourself, try to fix it and save money!! But always with a slice of humble pie and know when youre over your head so when it needs a big fix by a professional, you didnt give them a rats nest of "shouldn't have done that"
Wish you and the family the best.
DO NOT let that girl go!
@jamescaron6465 you have no idea the joy in my heart when we were stateside and drove by a NAPA and she said " NAT A SPONSAAAA"
@@frompdiggity LOL! That's Brilliant!
Hilarious.
What's it like to be in the future? Do we have flying cars yet?
My dad, who was a lifelong mechanic always said "If this was easy, everybody would be doing it!" You are always proving his point!
Gotta love the mid year engineering change.
Mazda had a period back in the 80's where you had to order parts on VIN number ánd year and month of production, as the mounting holes on parts like fenders seemed to shift a few millimeters almost every month........ how stupid can it get? You buy the part, hold it in place and it seems to line up just fine, have the part painted and when you try to mount it, the bolts just don't fit.
probably a supplier change, and someone started making the shutters wrong.
or there was an actual legit reason to change it.
That has been kicking my but for two weeks solid on a multitude of cars. Why on earth did Chrysler think it was a great idea to put so many options on 300 and Charger brakes? Even with the VIN it only narrowed it down to four. Then the rear control arms on them is about the same story.
All automakers do it all the time. If there is a serious enough issue or a design revision. It goes smack dab into the production line. Nothing wrong with that approach. Just have to pay attention
I work for Toyota and we have to deal with a lot of used cars. Infact that's all I mess with. If I ever have an issue I always hit your channel up first for research. Fix many cars due to your channel. Appreciate the detail in the research you do and informing others and techs of the issues that are not specified or mentioned in tsb's. Many thanks guy.
I'm a mechanic down in Tennessee and have run into that exact problem! I appreciate your time
"Extra care in engineering, Chrysler Corporation Cars, Chrysler Corporation Cares."
For you youngsters, that is a musical tune that was in a Chrysler ad campaign from days past. Many days past. So many days past they have obviously forgotten the tune.
I remember that. I am two quarters, two dimes, and a penny old.
It hasn’t been that Chrysler since the 1998 takeover that SHOULD have been stopped in its tracks by the FTC.
it hasnt been true since the 60's
so old in fact they forgot how to spell it...? S-t-e-l-l-a-n-t-i-s..??wheres the "H"?
Right... because not a single manufacture has ever changed wiring, or components.
Gotta hand it to Eric. He made me the mechanic I am today. Him and some of my other buds on TH-cam like scanner danner and Ivan. Lots of wisdom and experience going on in their videos
The is an old saying to the effect that knowledge is wasted unless shared.
All great dudes to learn from. I also like watching Hayes Mobile Auto Repair as well
Good stuff Eric! What they should do is include a male-female adapter that changes the wiring using a connector that connects between factory wiring and the new part to change the wire layout so if it's needed, it's included. But that would require thinking and we all know OE's... Cheap and "no thinking" at all!
I was going to reply with the same comment! Why in the world would they not include either instructions on the possible need to repin along with the blank plug, or include a short inline adapter? Either one should have been included with the new AGS, especially if they no longer mfgr the AGS with the old pinout!
@@RickOSidhe Two words: bean counters
$30, for a new harness. $32, for an adaptor..
Thanks! Another great video. Always learn something new.
I noticed your "wearing" your readers. Good move. Please accept this small donation towards buying a pair with magnetic nose bridge. I found them to be more comfortable and less likely to snag on anything. For that sophisticated mechanic's look 😊
One of my friends has the magnetic ones. His are the only ones I've ever seen.
* you're.
Heck ya! We got the old school opening! I sure missed the " Hey there viewers! Welcome back to south main auto channel."
I always hear "self made auto channel" and to me that name seems to fit.
@@jhonditch4269I always joke and say “self made” when he intros. Haha!
Chryslers what a POS car company 😂
$$$$$$...that's why.
His first videos he called himself Dr O. Watch one for a few minutes. He was shorta nervious and less grey too.
Great video! To answer the question: chrysler screwed up. This was an oopsie!lol! When they moved from the manufacturer in India to the cheaper one in Pakistan in 2018, they got what they paid for...
Grilled shutter. Active Overheating System. Mr. O never doubt the manufactures ability to not say anything about changing the product.
Fail open. Nice try.
I love watching your channel and videos. I think it's great what you do. I have been a mechanic for 30 plus years And have worked for a family owned business for the last 27 years. I really hope to 1 day open my own shop. I love knowing what I know and I Can't get enough of learning more. Keep up the great work!!
With respect Mr O, you would have found that without service data - because you'd have kept going until you understood the problem. Thanks for the videos.
Eric O, that was a great case study highlighting the power of service information (SI). It's puzzling to me why some shops still today don't invest in service information (SI), considering how valuable they can be. Just think of the time and money it would've saved this used-car guy if he had SI. We're all concerned about how quickly we can get the part and how fast we can install it, but often overlook the importance of verifying the repair.
Trouble is SI costs $$$$ and sometimes SI is brand specific so you spend $$$ for GM, $$$ for Toyota, $$$ for etc. You have got to consider that is the $$$ worth the use you will get out of it? Used cars are generally polish the turd and sell it. Do the obvious and ship it. They will not take the time to diagnose and use service data.
On vacation in Poland, and I still can't miss S.Main Auto episode👍🏻
Is it any-wonder SMA is the only utube vehicle mechanical repair site I subscribe to.
Hi Eric , this channel is better than a sherlock holms movie you use great logic! Awesome mechanic! I fixed the wifes sedona oil leak You are the man!
Thank you for going thru this. I was just going thru this and you helped tremendously in finding i needed an updated plug that our parts supplier had no clue existed. Thank you for posting problem childs.
Been watching for a couple years and this is absolutely one of my favorite channels! Thanks for sharing; I’ve learned quite a lot!
It's Chrysler. Probably their grill shutter supplier was replaced mid year and the new low ball one pinned it wrong so Chrysler, wanting to do the right thing but being out voted by the bean counters said "Ship it wrong. We'll change the harness with a bunch of cuts and splices to save 8 cents a unit". And that's what they did.
You had me at grille shutter , amazing technology from the 1920’s
Indeed Rolls-Royce did with simple bi-metal strip thermostat.
@@andrewwmacfadyen6958 We can't have that! it is too simple and reliable!
🤣
I had one on my John Deere "B" tractor from 1948. No water pump, thermosyphon only -- so no thermostat, just the manual grille shutter.
Yes...I believe they used those shutters on the older cars such as Rolls Royce in the day prior to the invention of the coolant thermostat and pressurized cooling systems.
Excellent figure it out repair. Massive prompts. Thanks for the video.
I’m believing your a electrical wizard. 🧙♂️
In my 38 years in HVAC, this happens because the OEM supplier makes a change without prior approval of the manufacturer! In some cases all associated cost may be charged back to supplier, but that responsibility chain ends at some point and here we are! If the OEM supplier had to pay every shop bill everywhere ! Things would change! It’s always amazing to me “they” have a reason for the change that of course benefits them! Too many people conveniently forget the person that bought the product, after all they aren’t important! Until the pink slips show up and plant closes! It’s all of our responsibility to lookout for the end user!
Good communication needs to be addressed at engineering. Oh, they just let go of their engineers! No joke!!!
I don’t think I will ever buy another stellantis product. One was good but the newer ones seem to be just junk!
I wonder how many other SMA viewers have their very own collection of Rock Auto magnets. Just spotted your locker and busted out laughing because I was talking about parts the other day and made reference to the Rock. My pal with the parts house has a fridge completely covered with them. When you gotsta have it and the normal channels aren't producing---ROCK ME!
Note to self. "just because it's new, doesn't mean it's right."
I've learned so much technical stuff on this channel, thanks Eric.O & Co. I hope you get to a Million subs soon.
"scared the puddin' outta me!" 🤣🤣🤣
Had a guy stop yesterday with a 09 youkon. He is a retired shop owner. His wife woke up went to leave for work and no headlights. She took his truck and told him to have it fixed when she got home. He stopped at my shop and told me 60 dollar bulbs replaced 3 months ago blah blah blah. I said did ya check the bulbs. He had a spare so we plugged it in. Wala let there be light. I explained to him those vintage gm eat bulbs and the fancy pants bright bulbs don't last as long. Also that good and new are 2 different words. Old dogs can learn new tricks.
What do you mean "they don't last as long." Why, I have a set that has the little fans on them that cool them to insure they last longer. They lasted all of a year. They did put out some serious light but you are correct they don't last as long.
My neighbor has a Subaru in which you have to peel back the bumper cover to replace bulbs. After she bought "fancy" bulbs from the auto parts stores for $50 for the pair, I got tired of replacing them after they went out a few times. I bought HD bulbs from the Rock for like $4 a bulb. Its been fine ever since. And I polished up the plastic headlights so she could actually see at night. 🙃
Y'all are learning the difference between upgraded and better
@@mph5896I have also problems with milky headlights. In Germany it's actually not allowed to do this but I don't care. On the other cars they never get milky
It is voila a French word, not wala lol
As soon as your said they sold him the shutter & new wiring harness I knew it was going to be the harness. This has happened to me more than once working on cars. Some things on cars they shouldn’t change. If it’s not broke don’t fix it. I’m sure it was to save “them” $ not us.
Thanks for the video. Enjoy the figuring out wiring problems. Those are the ones I hate to work on.😮
Happy Easter to SMA! Waiting to watch kid search for eggs. And now watching a SMA production! Better then the Easter Bunny, Eric O. Keeps going and going! Thank you!
At 7:55, "I would assume it would have come with this paperwork; they can't be selling these things and NOT telling people." Why just the other day I was asked at the dealership for my VIN for my vehicle. I keep it conveniently located in my wallet. I also try to keep in mind some specific knowledge about my vehicle. For example, I have a Ford with a Saginaw steering box; you just never know when those parts guys are going to ask for that information. I would have never for one single second ever thought any company, especially a highly reputable company like Chrysler, would ever make running changes and not tell anyone. The best part: Eric was able to keep a straight face while making that statement. GREAT VIDEO!
Christ Ler is no longer what it once was. and jeeps are worser than evar
Paperwork does come with new shutters. Unfortunately people toss them thinking its install directions. I do these all the time for body shops and keep a ton of these connectors on hand and the replacement has all 4 pin locations open. No splicing needed as its just a repin. If you have a good parts guy they will sell it or at least ask if you need it.
You're a rare breed. As a parts guy most people have no clue of even what make of car they drive or the year. I get hit on a daily basis with people that do not know the year of the car, engine size or Sub model. Then they get mad because you can not look up the parts.
@@andyd9900 At most parts suppliers in the UK, all you need to know is the vehicle registration number (= license plate number), as they have access to the central database of vehicle manufacturers' specifications for each individual car.
There is always something very valuable shared here! So happy to have gotten rid of cable tv and watch you tube and actually have socially redeeming content. I subscribe to some of those you also watch, they too are very skilled.
Had something similar with a fuel tank pressure sensor on an Expedition. Would have had to drop the (full) gas tank to access the sensor and re-wire the pigtail. So I cut the harness open at the PCM and swapped the wires there!
I had the same issue with aftermarket side mirrors on a 07 F150, the came wired incorrectly for my truck, swapped the wire connectors to match the factory plug and alls good. Keep up the good work, and thank you for the entertainment.
Bruh. Boom. Thanks for being here man ...
Who says you can’t teach an old dog new tricks. I always learn from your videos. Some of the other you tube “ mechanics “ are solely for entertainment, your videos are always educational where I learn from. I am retired now but still have a few customers that became good friends over the years and I do stuff for them and their families. I come from the older version where all the data you have access to was not available. Like you say at the end , without that data it would have been nearly impossible to locate and repair that issue. I wish there were more guys like you coast to coast where repairing things is the norm instead of parts replacement is the norm. One of your more famous sayings at the end of your videos is “ if I can do it , you can do it” doesn’t ring true here.
Great Saturday morning. Another SMA video. Always entertaining and informative.
In the intro, Eric O says, "not all auction cars are junk, but all junk cars are at the auction." The truth of this statement is that the "Used Car Guy" has been sending his purchases to SMA for over a decade to my _certain_ knowledge. Remember Viewers if the Used Car Guy is still in business after ten years then he is a good businessman. The Used Car Guy _knows_ Eric will fix his cars so he can confidently give his customers a guarantee.
Yeah FCA has been doing that lately. I had a jeep patriot 2.4 L a couple months ago the customer changed the throttle body on then it wouldnt start. He used an oem throttle body from chrysler and it came with a new connector and paperwork as well. He wired it in one wire at a time not realizing chrysler changed the pinouts on the new throttle bodies. He called me so i went out and troubleshot it, and wound up comparing the oe wiring diagram to the diagram on the paperwork he got and found 3 of the wires got changed around. Once i fixed it and wired it in proper, it started and all codes cleared when i cleared it and did the throttle learn.
I literally just went through this exact job today. Too bad Mitchell didn't list anything about this that I could find. Shuffled the pins around and works again. Good stuff! 👍
Nice work!
I was floored when I ran into this a year ago, I just checked my schematic and compared it to a newer one and found the discrepancy. I was glad to have my si that day.
Nice to see you’ve discovered the power of the headlamp! It puts the light where you’re looking! And that’s all you need…
Like as always Mr. O the first thing i learned with you as a teacher, is even looking at the car make a small case study on the problem. Use everything i can like interwebs, youtube, scan data, trying to make me a head before entering into the job. But sometimes i feel to impatient and want to wrench right away !!!!
Wow, great discovery, as I know dealers are not honest at all. Your customer is very blessed to have you there for him. Take care, thanks 😊
Hi Eric George here from Canada, Yes I agree with you on dealerships they just want our hard earned money, was talking to fried he had a ford explorer took it dealer because warranty wasready to expire he wanted oil change or just regular maintence he said , but he said he told them to do an inspection on it, because it was close to running out, they told him they could inspect it until he had a complete rotor and brake job, he ask what that would cost they told him 2000 dollars, he told them he wanted a second opinion, told them to just change the oil,/ so he comes home and takes it to a local shop here ,we only have two here,// they check his brakes and rotors and told him there was nothing wrong with his and they did not need to be changed, he said his warranty is gone so he will not be going to dealership anymore,/ as you have mentioned before they want to see you stuff you do not need, thanks Eric , always watch and find your videos very interesting, and you explain everything out with lots of details, keep up the good work, if you were running a shop near me i would be a customer of yours
Hey Eric, you forgot to beep the horn on the 3rd restart
Contact!
"Hey, it's THAT guy!" One of my faves, always makes me laugh my ass off.
Isn't it amazing how things get changed from one version to another with no apparent logic, rhyme or reasoning. Happens in a bunch of trades Eric. My theory is that "engineers" need something to justify their existence sometimes. Just a theory because like you I'm "just" a Technician (ie screwdriver turner)..... LOL Thanks for sharing another great trouble shooting mess. Glad the lady found her problem.
dont beat yourself up ,eric. the day before i retired i was still learning about my job.
Your old instructions always prove themselves. Test and verify! Great video and showing the need for good information to verify. Thanks and have a great Easter
At the end of video ,do a recap say clearly steps start to finish..problem , steps to fix…Thanks Eric..U R # 1.
I saw this happen with the old Chrysler K-car series involving the taillight wiring. Good show😊😊
I remember one of the CDJ(Chrysler/Dodge/Jeep) promotional Slogans from the 90's "It's a Jeep thing, you wouldn't understand" that has stuck for me at least, & rings so true to many things they do... 😅
Like you have said service data is where it’s at . & MICHAEL IS GOLD 🔧⚒🛠💥🇺🇸👍
Good catch Eric!
Great channel. Quickly became one of my favorites. Keep up the excellent content. Awesome job. 😊
Nice work, Eric! Nothing like finding out the manufacturer's parts are garbage out of the box.
It is great how you figure out how to make these repairs. I guess you have become the garage of last resort. Great job. I am glad that folks (mates) in Australia are learning along with us.
Any day with a new SMA video is a good day. We know you have been pumping out a lot of vids, probably trying to get to a million subs. You’ll get there, you should have at least twice that. What’s more important is to keep it real. Your shop and customers are #1. We know you will always do the right thing. Thanks.
Very interesting. Somehow a couple of my shutters broke off on my Pacifica and that happened 50 thousand miles ago. It works perfectly. Love your show.
From Iowa and salty roads.
As a mechanic on the collision side, I have done these many times
The thumping behind the dash after turning it off is the recirculation door actuator. They fail all the time on those RU pacifica/voyagers. You can see it moving back and forth trying to find its home position with the glove compartment out. Also, chrysler loves to change connectors and pinouts. I think OEM charger/challenger/300 fuel pumps come with a connector kit and I've had to change to a completely different connector when replacing a fuel rail pressure sensor on an RU pacifica.
Love these whodunnit analyse and diagnose video's. That scope is such a handy little tool.
It's about time you got a fairly easy one.
Eric, I've been watching your channel for several years.....I must say sure wish we had many more technical mechanics like you all over the USA.....these days we have folks that just like to change parts....As Mickey Pipes from HVAC also from you tube channel also from the great State of New York, he tells his employees 'If you not testing your guessing. Keep up the great work with the videos.
Yay! You're wearing your most important tool!
Love the used car guy specials
Awesome job, and it shows a dedication to your customers staying late getting it done. Stay safe, and God bless
You’re my hero Eric O 🤠😆 simple solutions 😊
Hi Eric, Like most dealers they don't want to carry 2 different parts for the same option,so you spend your time and money to fix it! Can't build it right don't build it! Mid year changes should be taken care of at the time of the change by the manufacturer! My opinion. Fat chance of that happening!😵💫
Wow, the things that can cause problems. This was very informative. Maybe the used car guy will get lucky and find a Pacifica with this part on it at Wilbert's of Bath (somewhere in the Mopar rows), and be able to buy it for a fraction of the cost of an OEM part. Now the used car guy has to hope that he doesn't have to also replace the noisy blend doors in order to make this car saleable.
Thanks for all the content!
I bet you rock at playing "Clue". Keep up the great videos.
1957 Lincoln Premiere - Parts house said it was the only year Lincoln used that carburator, the front shocks, and the brake shoes. It cost more to fix it, cause everything had to be ordered in. But it got fixed.
Funny I asked you about this model a few years back. Glad I listened to you!!!
Reminds me of Ford turn signal switches for late 60s early 70s cars. They came without the wires plugged into the connector because they had to be fed down through a tube in the steering column. The instructions were to cut the original connector off and plug the wires on the new switch into the new connector using the original to follow the color code. Unfortunately the same color wires weren't connected in the same way on the new switches. When the brakes were applied the turn signal indicators in the dash would come on as well both front turn signals.
Thank you for posting a link to that uScope!
You are the diagnosing guru. Learning a lot from your videos. Thank you.
Great work Eric
Who knows, there may have been something in the box mentioning the update, just no one ever pays attention! The number of bricked $3500 GM radios I see shops installing because they don't read the bright yellow sticker on the box saying "DO NOT TURN THE CAR ON." ;)
On the off chance this Pacifica finds its way back to your shop with a non-op AGS and/or an AGS code, there's an AGS cycle counts reset under Special Functions in the PCM. Good practice to do it anytime the shutter is replaced; I've seen quite a few go wonky a week later. :)
I reset it before it left 😉

Your little scope was very helpfull! Why manufacturers choose to change a pin-out or wiring harnas between two modelyears (applying the same equipment parts) just pokes my brain.
I once bought a genuine Bosch replacement blower motor for a Volvo- correct Bosch P/N and all. It was wired backwards- made all the angry air noises, but almost no vent flow. That was a head scratcher, but an easy fix. There were only two wires.
Send the dealer to Wilberts for the correct connector 😀
Some shady used car dealers would just leave it patched up and ship it. Let the new owner pay for the proper harness when throws another code.
I would suggest some dielectric grease as well, or cutting a drain slot in that wire loom, that wire loom is bad about trapping water and moisture that travels upwards to that connector and will corrode the pins. Lots of Chrysler active air dams and grill shutters suffer from this in my experience.
I've had a little DSO Nano with BenF firmware and a Quad DSO for years.
They're a step up from a logic probe. For some reason it's easier for me to wrap my head around the waveform on a screen but I don't trust them for actual voltage and frequency measurements.
That scope is a 25 buck amazon special DSO-138 in a fancy box. not that it is a bad scope. I use one for my low volt electronic projects and it works great.
How you charge it up and is it good for the private use?
I was surprised that they are so low priced. I still have my 40 year old scope which I haven't used for years. Wish I would have taken that money and invested it in Google or Facebook's IPO. Then money I paid for it invested would have made me a wealthy individual. I think I paid $400 for it back then. Of course it does a lot more than these $36 jobs, but only in accuracy and frequency response.
Another excellent step by step problem solving video, couldnt he have returned the wiring harness and exchanged it for the correct one, it seems insane they sold him an old style harness with a new style shutter or voce versa.
Normally electrical stuff is not returnable once you open it.
Dealer sold ya the wrong part? Tough. Shops like SMA might get a bit of a break but nit the average guy.
Another wonderfully designed American car!
Great detective work. Praise be for All Data.
Thanks SMA for the video. I had always thought the used car guy went to State Line Auction near Waverly or the one in Rochester, I never did imagine he had a car auction that close to his lot, now that is convenient.
Creative, thank you
GM typically releases only updated parts for service- but has notes that state other required parts are needed when the parts dept. pulls up the screen. As far as the cavity number four being closed, we call that a "flashed over cavity". Because ALL OEMs buy their connectors from the same suppliers, each OEM may use only certain cavities in their application. During prototype stages, they plug the unused cavity's with seal plugs which are little rubber plugs- this prevents WATER from entering causing green crusties. Once the vehicle hits SALEABLE status, the supplier has flashed over- or plugged the cavity intentionally to prevent water. The reason is cost- no rubber plug to buy and no labor to put it in- and they wont get lost or damaged. That folks is why you see this- and now it makes sense.
This is why you are the man! Keep doing your thing!
Jeeze, auto shutters . Imagine how well that system will work after five winters in the salt belt .
For what do you need this junk anyway?
So engineers can exhibit their ability to design failure prone levels of complexity and the manufacturer can claim 0.001% better fuel economy with faster engine warm up ?@@imtheeastgermanguy5431
@@imtheeastgermanguy5431 It is to help the heater blow hotter in the wintertime.Closed shutters allows the water to get hotter.Its actually quite helpful in that respect.Imagine 10 below at 70mph shutters open as opposed to closed.Much warmer heat in the cabin shutters closed..
Yes or when ice forms on those plastic parts and the motor and linkage is trying to move them. LOL

Great find, I proly wuddah modified that plug
I would love it if you started to review older cars. Let us know which ones to buy and which to avoid.
I would love to see a video on cleaning Direct Injection intake valves.
In 04 I remember Ford charging truck owners 90$ for a crank sensor on 03 trucks that should have still been under warranty. They then almost a year later released a recall with an updated crank sensor and provisions to refund people that purchased the 90$ crank sensors (all but 4-5$) "IF" they had a receipt of buying the aforementioned part.
