GMC Acadia: Hot On Driver Side / Cold On Passenger Side
Вставка
- Опубліковано 25 сер 2024
- In this video I show you the process I use to diagnose the HVAC unit on a GMC Acadia. The customer complaint is that it blows HOT air on the driver side vents and cold air on the passenger side vents.

im gonna move to Avoca so I can have you fix my cars lol. "test not guess" taken seriously and to a whole new level
I'm from northern Ontario, Canada. If my travels take me anywhere near Avoca and my vehicle needs repair, he's got my business!
Yep. Never did like throwing parts at a vehicle until I discovered the problem. That gets expensive. Most all computer problems started about 1982 with the electronic throttle body replacing carburetors. Hard to believe it's been that long...38 years and still have issues come up. Miss the days, in this case, of just shooting a little oil onto a heater control cable.
@@robj2704 Late 80s early 90s Chevrolet and GMC perfect example pickup coil in the distributor, the wires would break causing loss of fuel pump or spark or both. Throw a fuel pump at it and still be pissed when it quit again.
im in buffalo and considering making the drive for any of my vehicle needs.
I'd enjoy him working on my car..........however we moved from NY to Tennessee 8 years ago. Beautiful state, but I'm not moving back. Cuomo can keep it!
Ah yes the old "on the go life style" lol! Actually made me chuckle.
sounds like ron popiel more every day. just waiting for billy mays" but wait - theres more" lol
As always, I appreciate your gut (order the actuator) but that you truly diagnose and confirm the issue before firing a part at the problem. Well done.
Patdon me Rick, but I long for the days when cars heater controls worked with cables, instead of burnt out chinese actuators, made out of plastic.....keep up the good work, and explanations of proper troubleshooting procedures..
..
Waaaat? You assume that's what it is?

That's one upside to being a full-time mechanic, you see so many vehicles with the same problems that you almost know without having to test them what they are.
But you also test first - you 'da man!
Great video. Thank you!!!👌to anyone that has a similar issue, I replaced the actuator at first but it wasn't working, (doesn't matter drivers or passenger side same thing.) but my driver side was only stuck on hot. After I replaced it, it really didn't do much. I don't have the fancy machine so I had to recalibrate the temperature manually, you have to set the temperature to either hot or cold, (see the actuator turn) I set it to cold so now the electrics/actuator is set to cold. Now have to manually turn the thermostat all the way to cold so this way the electric actuator and the thermostat are aligned together to cold. From there I couldn't get the actuator to sit nicely to screw in so I turned the temp up on the dash a little until the screw holes lined up. The point of these instructions is so you don't ruin your new actuator by turning it manually and to calibrate it. Lastly I unplugged the 15 Amp HVAC fuse under passenger side to recalibrate it that way as well.
Eric is a dang mind reader also lol. I've been sitting here skipping around videos looking for something good to watch and up pops a new SMA vid. Thanks Mr.O
Try Mustie1. Always has something good going too!
@@youraveragejoe7644 lol I was on his channel before coming here :)
don't we all these days!
1. Camera shot up your nose ain't flattering...just saying. Especially after that rona smeeze.
Nothing like a good SMA goodnight story. Thanks Eric. Turn off the light on your way out.
He checked the edits, approved it for upload... Then hit the upload, added some text, and headed home... It probably finished uploading as he pulled in his driveway.
Fantastic under dash camera work here. Send the man an Emmy.
In my days, we had a Mr. Wizzard for learning things that were interesting, and aided in some school work. Now we have you to make up for this.. Education and logic, so much of that GOOD logic board that you posessis.. Thank you for that and your humor a great addition for we seniors.. Mrs. "O" adds so much to the enviorment...of SMAR Thanks again for the education and humor.. Alan
Hey Mr O just wanted to say thank for posting videos. You saved my sister $1,400 this week. Her ac was blowing warm and the dealer told her she needed a new compressor. But nope it was just aux/condenser fan was not working. $95 fan and she is back with ice cold ac. Thanks again Mr. O
Thank you for this. We just got my girlfriend’s 2011 GMC Acadia back from having the dealership work on the “transmission shifter module assembly” because the gear shift wouldn’t shift all the way into park, release the trigger on the gear shift knob, and let you turn the key all the way off and take it out of the ignition (a video on how to fix this problem without having to take it to the dealership next time would be glorious).
The vehicle was/is also having the exact problem you solved in this* video, but after the dealership told us, “...for the ac concern, the ac compressor is locked up and rear evap is leaking so both need to be replaced, cost of this repair is $2,516.81,” we told them to hold off on messing with the AC. I personally can’t afford an arm, leg, left testicle, and first-born child to “fix” the ac compressor when the passenger side blows cold air just fine. I think I’ll just order a $77 AC Delco or certified original GM parts actuator and see if that doesn’t just fix the problem.
Much appreciated; keep up the good work!
In a case where the fault isn't obvious (like a part that's physically broken), testing is never a waste of time. It's what separates the good shops from the hacks
(Holds cough) "Not trying to get the rona all over the masks" 🤣🤣🤣🤣 Some of the best commentary on all of youtube comes from this channel
Even though I am not a mechanic or auto tech, I still enjoy watching your vids because I LIKE YOUR STYLE.
Eric, you're an honest mechanic that only changes parts that are broken...There's plenty incompetent techs out there that just blast the parts cannon in hopes they solve the problem...Meanwhile the poor customer has a repair that is greater than a new car payment...Good Work!
I really like it when you also show the wiring diagram on your videos as well. It helps out tremendously on how to read it and find the issues from there. Nice video.
When my 05 Sierra did this, it was as simple as re calibrating it. The only problem was that I lived with it like this for several years. I found a way to re calibrate it from YT video, and it worked great afterwards.
I am fortunate enough to live a little over an hour away from SMA and I was just about ready to give them a call for a fix but with the help from some you tube videos, that Eric made I think I have solved my mysterious problem with my 2009 Nissan Frontier A/C issue. The blower fan worked but the A/C cut out on speeds #3 and #4. After testing my system the way Eric did on another Frontier that he published, I hit the books; Schematics, tested the circuits, relays, fuses, blower motor, Fan control switch ,etc. After all tests I took one last chance before driving to Avoca and installed a new blower resistor pack. It seems to be fixed now and I even found a loose set of contacts in the Blower relay socket in the IPDM engine room while I was testing. Thanks Eric for sharing your knowledge with the world, I would not hesitate to drive the 75 minutes to have "the Master" work on my vehicles for these weird issues. Thanks again. I hope it really is fixed. i did not check the amp draw on the blower motor however. I have been watching SMA videos for a few years that is the first place I go to research a problem and get a little entertainment thrown in as well. Love ya, E.
Thanks for taking time out of what has become a super busy time for you at the shop, to make a video and share with us.
Tis is a good day when South Main uploads a video.
9am here in Ireland hello world, another great post Eric wish it was that warm over here it's absolutely pouring down with rain and not very warm either and you wonder why Ireland is green it's because it's always raining
I had a instructor at the GM training center tell me years ago that they're not called "Trouble Lights", they're called "Concern Lights".
Great video as always. Keep up the good work.....
They're called money lights, they turn on when someone needs a boat payment.
@@youtubeuniversity6892 money light is on the instrument cluster and the concern light is what you used to find the money under the dash....
Thanks for your video. It helped me with my research, which fixed the same issue, and now everyone is happy 😊
Great video Eric. Can't wait till the day you do a toolbox tour video or a video on all the diagnostic equipment you have.
It'll be a one week special.
I'm a member of that "On the go lifestyle" thanks to that second cup of coffee. Great job Eric.
That GM design is not too bad, surprisingly. On Toyotas, you have to take the whole stupid dash apart to get to the actuator(s).
I had this problem and fixed it myself by doing a reset. turns out it was just the computer confused and had the blender door stuck, after reset , had to do it a few times (5 times) it now works better than ever. saved myself hundreds. Thank you UA-cam
Great video! Evidently the failed actuator is a common GM issue. Had three of them test bad in my Silverado for different control positions. There are a lot of YT videos about them.
With all due respect Eric, "Damn you!"
When you said, "That's as handy as a tee shirt with two pockets," I was just going to let it slide. But what you said got me thinking. I have bought many "regular" tee shirts with no pockets. I have bought a lot of "one pocket" tee shirts though not as many as "regular" tee shirts. Then I start racking my brain, I don't ever remember buying a tee shirt with two pockets! And, I am thinking, why, yes, two pockets would be handy but I can't find out why t-shirts have only one pocket at most.! Why, Eric, why? But you weren't done!! You showed the mini ratchet set and said, "You can stick it on your belt. Its good for those people with that on-the-go life style." Now, you got me wondering if I am one of those people with the on-the-go life style! So thank you for your "South Main Auto Repair LLC" fashion edition episode!!! My sleep patterns will be messed up with me thinking about this stuff!
Thanks for sharing, works well...drivers side is a whole lot easier than the passenger.
It's 5AM, SMA + coffee time! ☕
Same here but 5PM for me.
This man knows what the hell he's doing he's the best I've watched on this I've watched 12 of them he's very impressive any garage would be very lucky to have him be a technician for them big thumbs up to you and I've been around it a lot too but for him to diagnose that he's been around it all a lot more
I just repaired my A/C automatic blend motor assembly by disassembling the unit, inspected the gears, inspected the large final drive gear and its copper fingers that slide on the variable resistor pad. I put more tension on the copper fingers and used the surplus lube from inside and applied it to the gears. Reinstalled the unit and started my 2012 GMC Sierra with the A/C on, varied the temp setting cold to hot and back again, IT WORKS! Just my time and no parts.
The beauty of no car payments. I have a 97 gmc pickup that needed one of those actuators on the blend door. Had one screw that was behind a brace that was impossible yo get to. Ended up drilling a half inch hole thru the brace to get the screw out. Trying to get to the orfice tube. The line nuts are sized up. They just rounded off. Now the truck needs an evaporator.
"In the name of the Motor, the Transmission, and the Holy Distributor, grant unto this 97 GMC pickup its peaceful rest, Amen."
Saying Avoca: Ahh-VOH-ka or AH-voh-ka? I always thought it was the former. 😁. Eric, you can even make replacing an actuator entertaining and fun. Thanks as always.
I live about an hour north of Eric and up here when I see them mentioned on the news they pronounce it Ahh-VOH-ka. He may have "mispronounced" it just for the fun of it.
It's the first way.
Awesome! Like the Trouble Light in the Acadia, my 1977 Datsun 280Z had a Trouble Light in the Engine Compartment. I never used it!
Well done Mr. O. Proper diagnostic theory is never overkill.
Testing properly is far better than replacing a bunch of parts. Good job Eric.
Wera and Wiha are probably my favorite brands for screwdrivers, ratchets and sockets. Then it's Knipex for pliers all day long.
Bi-directional tools, so helpful. Thanks Dr. O!
I also like watching will it taco! My fave is when they try to find the places in the world where the food comes from.
Great job Eric it is so good to see your videos...
This issue is exactly what started with my wife’s ‘12 Acadia just yesterday. I will proceed with ordering a new actuator.
I JUST DID ONE ON A 2011 GMC THE OTHER TESTING YOU DID I DID NOT DO I GUESS IT THIS TIME I WAS RIGHT, BUT THE TESTING YOU SHOWED ME WILL HELP TO MAKE SURE THE NEXT TIME I DO IT RIGHT. THANKS YOUR GREAT HELP.
Nice diag process good way to verify your suspicion of the bad part @SouthMainAutoRepairLLC
Best UA-cam car repair video ever.... The detail is fantastic! It helps that I have that same problem on my 2012 Acadia
you are really good been watching for a year or so , i think you must be one of the most clever people in the town cheers Dom
Temps in the 80's sounds LOVELY. Try 118 in Phoenix for the past 3 months. 😞
But you can keep your 80's, I'll keep my rust free cars 😝
You forgot about the poisonous snakes and scorpions in Arizona.

Welcome to the wonderful world of Wera! It's the only screwdriver bits and hand screwdrivers I use they make outstanding hand tools and aren't stupidly priced either. Been using them for over 10yrs still have my original bits.
It’s always nice to know your products you work on and there common issues.
I love Wera.Their screwdrivers, ratchets and wrenches feel good and are comfortable in your hand.
I really appreciate what you are doing here. As a professional I sometimes have issue with the lengths that you go to to prove a problem. I still like the videos and I appreciate your time to show people how it works. I think you are the best automotive channel on the YT. I also think you should remove the aux hvac blower module and check the aux evap core for signs of refrigerant leaking. I replace them all the time, and I don't believe the tsb about copper dust from the aux blower motor either. Thanks for the video bud!
Im learning AC troubleshooting right now and I've definitely seen this issue on an equinox (bad actuator was already diagnosed by another tech).
That’s interesting, that model Acadia uses the same blend doors as my 2005 GMT800 Silverado.
I just had the pleasure of doing 3 of the blend doors this past spring. 2 are under the dash, one of which is at the base of the windshield. Oh what fun I had.......
Passenger side takes 3 minutes. It’s just beside the center console in the passenger footwell.
Rockauto has these from $21 to $70. Easy DIY job and at that price, trying it out (using the parts cannon once) sounds like a good idea.
That's how you earn customers loyalty and you fix it once and done unless you get a faulty part but diagnosing is always best to make sure
Your right to do the testing
To many garages just assume they know just changing a part will solve an issue
Many times a bit of diagnoses can save a customer a lot of money
Cheers Dude
All the part numbers are in the pan. That was cute the other day.
Got a 2012 traverse I'm looking at right now. I'm a Toyota tech but I like to learn knew systems, especially lately. I have codes for left door, right door and recirculation motor! Another tech looked at it and tried the HVAC control with no success. I'm looking at the diagram tonight and gonna do some testing tomorrow, but I think he got fooled on the no command from module due to the codes being set. Anyway thx for the video you always make it look really easy when honestly modern electrical systems can throw a lot of ppl through a loop, including me! If they are actually trying to read a diagram and diagnose that is. Great vid as always. Making hard stuff simple and to the point. Keep up the good work bruh.
As always excellent diag video master!
Love the Wera Toolcheck! Not only compact and pretty complete, but top tier quality... That little ratchet can take some serious torque too!
Changed three of those actuator on my Buick Enclave so far
How many does it have?
Your approache of this defect is absolutely correct, kudo's.
I would love to see you film your walkthrough for a New York State inspection. Me as a fellow NYS Inspector I would love to get some tips on how to properly look over a vehicle especially to see the difference from Long Island to Upstate NY. love the videos keep it up!
Nope we both follow the same rules 😊 believe it or not where I live is still in the same state as where you live
I have bought several WERA products. They are very well designed. I use them everyday...
Unless the motor is bad in the actuator, I've had pretty good luck taking them apart, cleaning the contacts and adding fresh dielectric grease. Problem is, if you do that, you can't guarantee it to the customer, so it works if you're doing your own vehicle : )
usually on these vehicles the reistor burns up on the board. I was kinda hoping he would pop it appart
@@daveyio87 he'd have to change his middle name or nick name to Ivan ;)
I have a problem with my driver window motor. Every few years I have to remove the panel, wacky the motor & put it back together! I have a new unit, but I'm only gonna change it if the old one explodes!
If the actuator is going "click...click...click", they you're outta luck. Most likely a broken gear tooth.
@@miketeeveedub5779 That's exactly what I found when I replaced an actuator on my Dodge last year. At least the Mopar part is made in the US.
2:58 bless you
Much better this video than the last one.
Dude, the amount of knowledge in that cranium of yours is incredible! Who says the trades are easy? If we could convert your knowledge and common sense to a measureable index it would be greater than a law degree or a doctorate in phylosophy. Sorry, that might not be a compliment now that I think about it. Anyway, it amazes me how much you know and how creative your brain is so you can troubleshoot so many things. Thanks for the enjoyment.
Legend has it, if you are early enough, EricO puts down the multimeter pins and replies...
Did ya know Eric and his family don't have Internet at their house? The cable lines are miles away from their house. They do have Internet at the shop ... which isn't open at midnight.
David Null Should we be worried that you know this?
@@jonf1812 --- he had mentioned it in videos a while back.
lol
Plus he works a million hours a week, has preceptor technicians, a wife and a bunch of kiddos and doglets. He's a busy dude.
Thanks for the walk-thru and diagnosis procedure. Always great to start the day off right with a SMA video. Thanks Eric!
Doesn’t that hot and cold thing depend on which spouse is sitting on which side?
Never overkill,always best to back up ideas. Great videos
How many spouses do you have? :)
guss whu lmao
Those Wera Zyklop Mini ratchets really are a lovely thing. They really are "mini" - as in ~3.5" long, hide in the palm of the hand dinky. Had one in my tool bag for a few years now and it is a joy to use.
Sorry if that sounds like a shill - it's not, just a happy customer.
I have the same 2012 Acadia. Just changed the actuator that directs air flow to bottom middle or top. Was on the passenger side and what a PITA to get to. But got er done. Didn't have to recalibrate. Plugged in the new one before mounting and adjusted the gear to the same position as the old one then installed.
I've replaced 5 of these so far, the front three on my Traverse and a couple on a friend's Enclave, so far none have been for the rear AC/heat. The two on the right side are bit of a PITA, and so is the fuse you have to pull to have it recalibrate if you don't have a scan tool. On all of them that I've replaced it was a through-hole resistor that crapped itself all over the mostly-bare PCB, so in theory you could just change that if you have the time.
Probably not seeing rear unit actuator failures because they are seldom used.
Breakfast with Eric O. Another great day!
Fun tip with the autel scanner. If you push and hold the camera icon it'll take a screenshot
Thanks SMA!!!!... I've been trying to learn how to diagnose these 5 wire actionaters, to no avail... Even though my truck is dual zone manual, the testing should be the same... I owe you one... Stay awesome... Peace...
i wish i had a shop down the street like yours . GOOD JOB
Thanks Eric...I have a lady car that dose the same thing...same vehicle but the car is 2010..she supposed to bring it back in later this month..now I have direction to go to now..Your video r great..keep them coming
Wera, another great German toolcompany, thx for the tip on this piece of equipement!
I’ve never gotten in on an SMA video so early
I knew what this was as soon as I saw it. I had this happen in my Ford Fusion. The cool thing is you prove it with diagnostics. On mine you’re supposed to disassemble the whole dash to change it because it’s in a horrible place up high in the dash to the right of the steering wheel. I ended up changing it with a 3 foot Phillips head from the side of the dash on one screw and a thumb wheel socket on the other. Total nightmare.
Loved belt buckle for people with on the go lifestyle!!
Belt clip!
I have a smaller bitholder and I don't use it often but when it is needed I love the thing. I like that kit though as who doesn't lose bits all the time. I hope you put that on your amazon store cause I think you just sold one! Another great vid please keep it up! Thanks
Had to change this on my '03 Silverado last month. Drivers side went hot as could be in South Louisiana humid heat. Also had to change the mode door actuator a couple years back as it would only work on defrost or the floor. Cheap fixes, but a little snug to get to. That Wera tool kit would've been nice to have!
Thank YOU for the lesson, never give up! Great video, always interesting..
It was very informative for those of ho love to do-it-yourself
Like the gm blend door actuator that tell you when bad. The clack at you like an old hen.
Always informative always fun...thanks for watching? Thank you!
Very good good information you really know what you're doing I've watched many of these two guys know what they're doing the others I wouldn't give him a screwdriver thumbs up to you
U da man!!! And just remember viewers, if he can do it, we most likely can't, because we don't have all the tools, scanners, testers, CPUs, and fun toys that he has!
Another fine repair, as always.... 👍
Glad to see you finally got an easy one, well at least you made it look easy.
Did a mode door actuator on a 05 subie legacy today. Had to break all the screw drivers, you don't need one stubby you need like 5 all different lengths. That's what she said.
I just changed one on my impala yesterday...and guess what it was stickered made in china.(globally sourced parts- genuine Chevrolet ).and of.course it.was the hardest one to get to...and like you-i just happened to have one handy..lol... common issue they fail...thanks for.the v-jay
Keepin it cool at South Main.
G'day and greetings from Tasmania Australia, it's amazing how you check the vehicle by plugging in scan tool that goes through the cars computer and gives you a very good idea what's wrong with it. I'm showing my age but I remember the big red diagnostic cabinet with all the leads and now you can hold the led read out in your hands amazing technology regards John
New camera works good. My eyes Itched when you cleaned off. the corrosion and sprayed the brake clean.
