- 2007-2014 Suburban, Tahoe, Yukon, Yukon XL, Silverado, Sierra (2007-2013 on pickups). I had a hard time finding accurate descriptions/locations for the various HVAC actuators. This is for the auto climate control setup. Just a quick recap: on the driver's side above the gas pedal is the mode selector actuator, on the passenger side under the cover just to the right of the console is the driver's side temperature actuator, and behind the dash center panel is the passenger side temperature actuator.
Thank's for the follow's. I'm not a proffesional "TH-cam" poster, so sorry if video's are not professional looking. Just a guy sharing info.
You dont have to be a professional TH-camr. What you posted here is exactly what most if us are looking for. I've been outside all day screwing around with this truck looking for actuators. I subbed to your channel for this one. Good job my man. Thank you and keep it up. 2008 Chevy Suburban.
Hey man thanks so much!.. my driver side just went tonight... you have saved me a lot of looking and reading much respect and thank you fro taking the time to show others. God Speed
Once again visiting this video as a reminder of their locations. Thanks again for this!
Exactly the information I need, no lengthy discourse on irrelevant points. Thanks!
Love it man. Thank you so much. Was going crazy trying to figure it out. Thanks a million.
You sir are amazing. Thank you for posting this. Couldn't find this info anywhere
You are THE man! Alldata has nothing for these components.
Lifesaver!
You Sir, are a Saint and a Scholar. Couldnt find location data on these easily, Ironically these are in the exact same locations as my 03 trailblazer from years ago.
Thanks. Was looking for mode door. I appreciate you.
🙏🙏🙏 thanks man. Definitely been digging for this info
THANK YOU!!! I needed this 💯🔥
this just saved me so much time, thanks dude
Awesome. Straight to the relevant info. Thanks!
Thank you so much for your video..helped me a lot..much appreciated it..
Great job sir thank you you helped me tremendously
Thanks so much for this helpful info.
Thank you Sir!! you just help me a ton
Thanks Norm! Super Helpful.
Great video. You helped me
Thank you for the information. God bless you.
Great work! Thank you!
thank you so much sir bcz i couldn’t find them im just gonna replace all of them and the front controller too
Super helpful thanks. TRQ made one but literally did not explain what each one was.
Thank you for the video
Thank you for information
Thank for this. My 2012 suburban has air coming from the small vents in the dash that point to the side windows and and feet when I have it on feet only. Does yours do that? Or Do you think it’s the one under the driver side?
Thank you so much!!!!
Thanks bro!!!
Thanks for sharing.
THANK YOU !
Gracias por compartir
Big help!
Thanks!

Do you know which one control the rear ac vents?? Having issues with drivers side and reak while passenger side works fine. Just had it looked at and now everything blowing out of defroster vents.
Blower motor resistor for blowing out of defroster vents
Thank you
I’ve got cold out the passenger vents. And just air blowing out the driver vents. Maybe this will help.
So my two front AC works fine but the rear one doesnt work, which actuator controls the back ac ?
I’m curious what you mean by “mode” control. My heat and a/c works fine but we are getting it randomly switching vents. I’ll have it set to floor only but get heat in our faces or vice versa. I’m wondering if the driver side one is the one I need to replace?
“mode” controls the floor vent, defrost vents and etc so yes it would be the one you would need replaced
So does the mode door actuator control heat & ac for the back row seats? I’ve already replaced the blend door actuator under the panel in the hatch and it’s still blowing out hot air. 2008 Suburban
Mode door actuator. Is that the one that allows a change from hot to cool air or is it the one that changes airflow positions from dash to floor
Thank you thank you thank you and so on x100,000,000.000 times over thank you my truck had me 😪😵💫
Nice Vid! My driver side blows hot air, passenger side blows cold.
So you are saying that is the blend door actuator for driver side is, under the glovebox?
Thanks for the video!
Yup. That is what I replaced on this truck. It's not that bad to do.
@@normli8606 Sweet man. Thanks! I was getting ready to fire up alldata, too. Then I saw their prices more than doubled since last year.
This helped me so much. Just got in to my 2012 sierra and it's blowing hot air on driver side. Im so glad I don't have to take my dash apart.
I replaced this and it didn't work. Do I need to do the mode door 1 begind radio?
@@fucktheleftFJB I realize this is one year later, but I'll answer now for other people searching this: If you have hot air blowing onto the driver while the A/C is on, then change the actuator under the center near the floor. The one by the glove box, on top, is changed when the passenger gets hot air with the A/C on
So my passenger side doesn't change Temps stuck on cool no matter temp change and my rear vents in roof are all stuck on heat when ac is on and now only get heat from defrost. Idk which actuator at this point i need to change
So the one on the driver's side control the vent doors
Any video on how to actually replace them? TIA
So the mode selector is for switching vents and not temperature?
All of my front vents/defrost work when commanded.
I ask because I only can get ambient air or A/C. No heat. Either side. Doesn’t matter if the temperature is locked either
Rear zone is fully functional
Yes, the mode door changes positions. If you don't have heat on either side, I'd open the hood and check the heater hoses on the firewall to see how how the hoses are. It's possible that heater core is plugged, or thermostat is stuck open. With the heater core hoses, one should be hot (inlet) and the other one would likely be little cooler (outlet). I would find it hard to believe that both temperature actuators went out at the same time.
Same issue. Heater hoses fine. Ever find the fix?
Dear which one is to stop the outside fresh air, i am getting all outside smells instead of pressing the button
Which actuator controls outside air blend? Or blend door? I get cold air blowing when it's freezing out but when it's not so cold I'll get a little warm air. Has to be outside blend door. I had same issue with a Tahoe I had. The blend door was stuck open introducing cold air.
I should mention this problem I now have in my 07 Avalanche.
I also have this problem in my 07 avalanche but only cold out. Just changed the blend door under passenger side. Would I do the mode door next?
i have same if u fix it tell how please
Thank you!!!!!!
As you said, this information is hard to find. Mine are working but erratic. I am going to try a recalibrate first
What's the recalibration procedure?
The mode actuator switches it from your face to floor/feet etc. correct? My driver side air is blowing hot and I know you clearly started to change the one on the passenger underneath by the floor but for some reason everyone keeps telling me to do a different one🤦🏼♀️ your help would be great!
Stated *
@@caseylowry4229 correct. Is the one that is accessed from the passenger side. Its just above and to the left of where the passengers left foot would be. Seems weird there, but thats the one. If the temperature doesn't change that is the one that you'd want to change.
@@normli8606 I manually moved the door under the passenger side after taking off the blendor cuz I am only getting cold air. I can hear the flap opening and closing but I am still just getting cold air.
Which actuator controls the recirculation door?
top right, passenger side. under the airbag.
I have a 2014 gmc Yukon same as this body style. I’m having trouble with my car not blowing the correct temp. If it’s hot outside and I want the a/c on and I set it to 60 which is the lowest setting it will blow heat and if it’s cold outside you have to turn the temp all the way to 90 to get hot air. Would this be the actuator on the driver side that needs to be replaced since you said it controls the temperature?
That is what I'd look to replace (left temperature actuator). Sounds like it's getting bound up and not moving to the cold side, hence why you're still getting hot air when you set it to 60 degrees.
@@normli8606 so you mean the drivers side when you say left side?
@@jaredvera7079 yes, drivers side actuator.
@@normli8606 thanks man!
What about how to fit the vents in the rear on the ceiling
Those will be in the back hatch on the passenger side under the window panel
I have a 2011 Suburban LTZ, cold air is blowing but I can not get any warm air. I can direct it to the proper places with the controls but cannot get any heat. Both heater hoses are warm so I know it iis not a circulation problem. Which actuator would control if the air is pulled past the heater core or not?
I'm guessing that it has dual zone (driver/passenger selectable temperature's). Can you change temp on either side? If you can change temp one side but not the other, then it would be one of the temperature actuators for whichever side is not changing. I see that you say heater hoses are warm. At operating temperature they usually are pretty toasty. What does your temperature gauge on the dash show for temperature? Possibly bad thermostat maybe if the temperature isn't too high.
@@normli8606 I get no heat from either zone no matter what I set the settings at. I only get cold air, and by me saying cold, I mean outside tempature air, not a/c. My temp says 210 and that is what it always says. I should have worded that differently but my heater hoses are 'pretty toasty'. I don't think it is a faulty thermostat as the temp guage does not indicate that.
Did you ever find out which one was the problem. I have the same issue on my 07 avalanche.
@@KendalGoodrich I have the same problem in my 07 Avalanche. I haven't heard anything hear about the outside air blend door. That's what was stuck open in my Tahoe. I get warm air if it's not cold out but when it's freezing out It just blows cold. Has to be outside air.
@@phillipbingham4470 I actually figured out my issue. It wasn't a blend door issue, but a restriction in my heater core. I pulled the lines, flushed the core and reversed the flow through my core and been heating up fine ever since.
My 2008 Tahoe blows cold in the back and warm in the front. Which one would it be.
In the front, is it dual zone (driver & passenger)? When you change the temperature does it change at all?
I need to change the passenger side actuator. Do I need to remove the whole dash to access it?
what exactly are you having issues with. I just tore my truck apart to find out the actuator i needed is hiding near the passenger floorboard. I know where they're all at now!
@@jonathanbickham1088 passenger side doesn’t blow as hard as driver side. It’s cold just not as strong.
I can’t switch from fresh air to recirculation, and my a/c symbol flashes but it never turn on.
Simple to the point. Now which one controls the rear? Lol.
I'd think it's on the rear HVAC unit. I believe its on the rear passenger side, between the wheel well and and of the truck.
Could I manually switch the temperature control too cold air
If you manually switched it to cold, you would probably have to take the actuator motor apart and rotate it manually and then it would be stuck on coldIf you manually switched it to cold, you would probably have to take the actuator motor apart and rotate it manually and then it would be stuck on cold. Without the actuator on their, the door would probably just flop around and heading on how much air pressure is on it.
This is the same for 1999-2007 as well
Where’s the one for the rear?
Would anyone know which actuator I should be fucking with that controls AC and heat? My drivers side AC works great, but my passenger will only do heat
I'd look to replace the passenger side blend door.
What is mode door? What's it control?
The direction of flow
The direction in which the air flows out.
Piece of shxx design on these blend doors. Amazing garbage design for access.
are they all the same part number
