The blend door on my grandpa's truck went out and this helped us fix it. Thank you so much!

Thanks man. This is already my second replacement. I had a shop do it about 5 yrs ago. Anyway, your vid saved me shop costs. Only took like 15 minutes tops.

Awesome vid man. I've been having this problem for a while now and it was driving me insane. I ordered a new actuator and took the old one out. I moved the "door" to the heat position for the time being until my replacement actuator come in. Thanks again man.

Awesome! Why did it take me so long to find this video? I've been dealing with this problem for years and I knew what the problem was. For whatever reason, every how-to vid I found led me toward pulling the whole dash and hours of work. Watched the video, clicked your link, ordered the part, Amazon delivered in 2 hrs!, pulled the cover and the old actuator, replaced with the new!! Got a whole day free ahead. Thanks! WPS!

THANK YOU! My '05 had just cold to the driver's side, which really sucked as the weather's geting colder (passenger side worked just fine). I ordered the AA Ignition part from your link on Friday, it showed up Saturday evening, and after about a half an hour on Sunday morning it's working perfectly. NOTE: I also had only two screws holding the old actuator in place...and mine were 6mm, not 7mm.

My Silverado has been doing this for a while. Pain in the ass! Then the HVAC blower motor resister went out, so now I’m gonna finally change it! Thanks!

Thanks for the video. I ended up having to re calibrate after replacing the actuator.

Awesome tutorial man thanks! Took me 20 mins, mostly spent trying to locate my socket set! Also, tip for anyone with an 03, the screws holding in the actuator on mine needed a 7/16 instead of the 7mm

Thanks for posting this video. I ordered the part of Amazon and fixed it myself today. Probably save a couple hundred dollars!

My side blows flaming torches while my passenger shivering in a blanket! Will try this soon thank you for taking the learning pains out of it!!

Thanks for this! I just had this happen on my 05 Silverado, and saved me some headache diagnosing. Don't have a replacement part yet, so I manually flipped my door to cold :)

You just saved me a bunch of time. I'm a mechanic here in Jacksonville North Carolina with a Silverado with the same conditions. I knew it was a blend door issue. Problem was location. Usually its the one on top. Like yours it to is a dual controlled system. I never would have thot to go to the bottom of the HVAC. Generally those usually control between hot and cold and not left and right. I was set tomorrow to pull the airbag and duck to get to the top one. That would had been a waste of time. THANKYOU VERY MUCH for your video!

Awesome, thank you, no mechanic knows what wrong, thanks. 👍👍

Thanks for the video. I was having problems with heat control. I installed one of these today and it seems to work better. I guess they don't last forever. Mine is 20 years old. Thanks again for the tips.

Thanks for the video man. Ordering mine today. My 05 is miserable right now.

GREAT video! I just bought mine on Amazon, and looking forward to fixing this problem on Saturday.

Exactly what I needed to know! Sweet video.

Thank you Dustin, very helpful and enjoy your presentations.

A couple comments. First, this is the ONLY video I have found that tells me whether or not I am onto the CORRECT blend door actuator. My Suburban has three, and there are plenty of videos that show you how to change each one, but they don't tell you the symptoms of which one controls what, so you don't know if you've got the right one. This one CLEARLY told me that this actuator controls the temperature on the drivers side, which was my issue. So I was able to know which one to change out (VERY helpful). Second, it's the 7/32 for the actuator screws and the 7mm for the big plastic cover screws. Lastly, if you have a vehicle with a center console, it is a LOT harder to reach and remove the furthest screw, but I found with a 1/4" drive socket wrench and the 7/32" socket, I was able to blindly back it out and put it back in. Be sure to manually turn the shaft on the actual door to line up with the flat spots on the actuator collar before you push it up into place. I put one screw in (the easy one) to hold it into place and then hooked up the wires and tried it out before I put the difficult screw in. Once I confirmed it worked, I went to the trouble to slowly ratchet the hard-to-reach screw into it's mounting hole. Good video, though, and thanks. I fixed my frozen-driver problem for $31!

Just watched both these videos, thanks man I been suffering this whole hot season without ac and found out it was just this..

They aren't usually actually out or broken. Being a broke retired engineer, I pulled my first one years ago, plugged it back in while it was out of the vehicle and turned the key on. To my surprise when I changed the temp, the actuator turned a little and jammed up. Quickly I grabbed my Leatherman multitool and helped it. It let out snap and then turned to where it should have for the position i had adjusted it on the truck. I stuck it back in and it worked fine until I sold the truck years later. I just clicked on this video for location of the drivers side actuator. Im an old hot rodder so I still find pasture and barn finds all the time so I see this pretty often. PS. Old farmers are bad, or good in my opinion, for having several pickup trucks to drive and something as simple as a heater not blowing warm air when its cold outside will make them park an otherwise perfectly good truck. I will say I've had to take them apart in some situations because they were that jammed up and I've also had to steal a plastic gear out of an old one, rob Peter to pay Paul, in order to get some working but as far as I can remember, one or two that were broken so bad that I actually had to purchase a new one. Good luck everyone and I hope the barn truck information i shared doesn't come back and bite me in the ass.

You haven’t lived till you change that SOB out with a center console blocking the Hell out of you! Mine wouldn’t line up with the shaft till I connected the wires and turned the heat on for a few seconds. Finally got it in and buttoned back up, works great now. Thanks for the video.

Thank you! It is a quick fix I just needed to know exactly where everything was. Like the video and details. Thank You!

Just wanna say thanks man , I don’t have a pain in my a** any more...you rock dude

my man....u the real mvp!!! my silverado just did this now i have the solution

Thanks for tutorial dude. I will attempt to DIY for my dad's 2004 Silverado. Almost identical to yours. Lol How did you hold open temporarily? Did you use a screw? Thanks Dustin

Excellent video, appreciate it very much, know I saved a lot of $'s. Took me (actually my husband) about 30 mins, because he constantly looks at the video. He wanted to share that he used a 7mm socket to remove the screws on the cover, which he took completely off, and a 5mm socket to remove the actuator. His truck is an 04 Silverado 2500HD. Thanks again!!

Perfect, Thx man, for me it went good, to make it easier try laying a vanity mirror on top of the transmission tunnel to see what your doing, for me I had to turn the shaft on the blend door to clock match the actuator socket. 😎

Thank you, my man .I know this video is basically 4 years old, but this fixed my problem here in Union SC ,when the heat is like hotter that HELL 😅

Thanks for the help. I replaced the actuator in my 2004 Chevy Silverado and my a/c no longer randomly turns hot. Thanks!

im looking to see if my local part store has it . there are numbers like 3 4 5 6 is there a difference. my 05 gmc sierra is doing the same thing

Where'd you get the emblem cover on the grill there?

Great video Thanks for making it very helpful

Dustin, did you ever post the reset for this? Mine is still confused where the controls are vs the door.

Great vid! I had that problem and it fixed it.

Does the new blend door actuator you linked in your video still work as advertised? I have to replace the one in my 2003 Silverado. Thanks,

Thanks for the video and the part link. Easy fix.

Thank you sir! The only video I could find that actually gave me the socket size. 👍🏼👍🏼

awesome, got one arriving today for same problem

Thank you so much. Uou explained which controls what side and that was a God send. Mine is a 2004 siverado with a full length console. I read in comments the guy didn't have to take out his console. I'm hoping I don't. One video shows a guy with seats n console out. 😮 omg. I hope not. Thank you for your detailed, right to the point video. Wish you lived in West Texas, I would pay you to fix mine. Thx so much.

Update on pricing on oem. 5/27/20 since all GM plants were closed the prices of these exploded. OEM replacement was $175. Just placed an order for one off your link, that warrenty. Hopefully I wont have to replace it down the road anytime soon.

Which video shows how do relearn the blend door? I got to replace mine and I will probably have to relearn it. Thanks for a great video!!!!

Great Video! Thanks!

Is this for the left side by the window too?

Is there an actuator for both sides of just 1? I have no heat on either side. 04 Silverado. Thanks!

Great video. Thanks bro

Great video. Thx sir.

Would this be the fix when I have full defrost on and air still comes out of the dash and floor vents and vise versa?

Fixed the problem thank ya

Thank you! Every other video has been about temporary fixes...

Very helpfull.thank you👍👍👍

So I've got an 03 and the temp controls work fine but the vents don't change. Before I buy the wrong parts or anything are all actuators for vents the same and do you know where the one Im needing might be located? Thanks...oh and I'm in Arkansas too...WOO PIG SOOIE!

Great video!! Thank you

I need one of these videos for the driver side on the 2014 model

I was able to reach my hand into the back panel and disconnect the actuator to lock it on cold (after doing a reset my phone, letting it run for 2 minutes, turning it off for 30 seconds, turning it back on). Didn't even have to use any tools other than the needle nose pliers to take the fuse out! Now to wait for the part to arrive

Can I use a blend door in place of my mode door ? Or will it not work? They are exactly identical

hell yea thanks man , all i hear about is those blend doors , youd think chevy would find another vendor that makes those and quit bullshittin , but o well , thanks man for showin how to change em out!

Thanks for rthe video and the part link. Easy fix

Well done and explained

Thank you for your video....when taking out the actuator on my 04 silverado, the nub piece was stuck in it and had broke off into the actuator. now how does that get fixed lol

How long did it last I've replaced 2 times in 5 years

Nice vid. Thanks man.

are all actuators the same for all 4?

Very useful. Thank you

Is this the same process for a 2002 Chevy Avalanche?

Thanks!! Same on 2006 Chevy 2500 HD.

I was driving down the road with cold air.. only to get hot air in all my Vents... So I stop the truck to investigate... Turn the truck back on got cold air again.. so how many does a 2004 Chevy Silverado has..

Does that work if it blows hot on the passenger side?

Any ideas on what to replace next? I replaced the actuator and did the relearn process and it didn't solve the issue

Will this work for 04 Escalade

Man thank you I've just been Riding around freezing my butt off because my GMC is stuck on cold 🥶 on the driver's side and it has been 7 to 14 degrees for the past few days And even though the passenger side has been blowing hot air the cold overtakes it and it's still cold in my truck like there is no heat at all.

I'm in northern Arkansas too. Where exactly are you?

So my ac is stuck in top vent n feet mode i jus got the part n hopefully i can change the mode

Do I have actually have to unplug the battery or is it only recommended

my AC blows just fine, the issue is my blend door actuator is on top of that housing. I heard your door going from hot to cold. My 88 model was so easy to swap out all of them with no issues...this 2003 model isn't very user friendly. My book states to drop the whole unit.

Driver side actuator is missing I got one from Amazon with guide base as a kit need to know how to install it

Hey Dustin, I watched one of your videos the 2003 Silverado. I have 2003 GMC. The problem was heat on driver side cool on passenger side. Replaced the actuator. Wasn’t sure if I needed to calibrate. I have the automatic control s long story short didn’t see change. Does the actuator or ac need to be reset?

Great video! Does replacing this part correct low air flow out of the dash vents? My blower is running full speed (checked voltage to blower and it changes speeds with dash setting), but not all of the air comes out of the dash. Sometimes something changes (blend door opens?)and I get full flow. "Relearning" seems to help for a while, until it does it again.

Do i have to line up the actuator

where is link for part?

well done and thank you

Are there two actuators? A driver and passenger side or just one?

Is this for the driver side or passenger side? Thanks

If you have the center console it’s a bit more work have to take the seats out, pile the cup homer and cigarette tray out then disconnect the harness for the console and lighters remove the two bolts where the cigarette lighters are and now pull it away. Then follow your video.

Where are the links man?

great helpful video, but just to put this out there, my 04 had 5mm screws holding it in not 7mm and the one closest to the seat was a locating pin that fit in that hole and it was not using a screw there

Thanks for the video, I dont have the bench seat I only have the 2 person seat in the from of my 2004 Silverado I can fit a ratchet on the front screw any ideas? I unplugged it . it's now blowing room temp air, better than hot air lol

Will this also fix the problem if my a/c is on and drivers side blows cild but the passenger side blows hot?

These are deep well sockets not standard right?

Only problem I see is you described it as replacement of the drivers side actuator; but this was the passenger side. And they only have 2 screws - the front one is just a little tab for alignment I assume. I replaced my passenger earlier, as you did, but believe my problem lies on the drivers side, So I was hoping that was in fact what you were covering in the video as you state in the description.

I was going to ask why the bottom of the dash was so rusty, then I saw all the moisture under the dash, not a good thing, but I needed the video to know where and how this was so thanks

Hey would anyone know why my defroster won’t blow air at all everything else works but when I do my defroster it won’t blow air at all

How many actuators are there? Mine blows cold then switches to hot ? Is is same side or there is on driver side as well ?

Anyone know if this part will fit the '07 Silverado Classic? Amazon says it won't

could someone help me a bit ? My ac works sometimes then stops working for a few days again and sometimes it may come back on. I’m not sure if it’s my compressor or the actuator. However , I think it may be the actuator because I can hear the it going off as soon as I start playing with the controls ?!

Is it the same problem if you have heat on the passenger side and ac on driver side

I've found with my 04 chevy silverado 1500 if I just put the truck in neutral, ( or if not moving...) but turn off truck, and re start.....it resets it. Oftentimes that does the trick for my commute. However I just ordered the part, and will be using this vid as my guide to replace it soon. Thanks

What if it still stays hot when I have it on cold

Thank you!

When u hear that hissing outside you KNOW it’s hot AF!
