What about the blender which one blends the ac and hot?

Im have a problem with mine every time i tirn the key on my motor will tirn all of the way to the right and back to the left and hits the stop on it so itts a 90 degree and it should be 1/4 how to fix it my part in new

Of course the one I need to change is way up in there , why couldn’t been one near the glove box lol thanks for the info 😂

Which actuator would be the one that controls the flow of cold / hot & outside air ? When my AC is on and blowing just fine though the vents it will at random times start to mix warm / outside air with the cold AC air and I have to turn the car off and then back on and it blows ice cold again for a while ( could be 10 min , could be an hour ) but eventually it will start letting in warm outside air again , and also does the same in the winter with the heat on through the vents it will randomly start to blowing in cold outside air . So it's basically doing the exact opposite depending on the season . Would you believe it to be the blend door actuator? Since all vents work as should and direct the correct flow for the control settings inside car .. it just will open what seems to me to be a blend door or outside vent that let's in outside air randomly... BTW this is on an 07 trailblazer Any help or guidance would be much appreciated and a money saver as I don't want some mechanic guessing and replacing actuators that don't need to be replaced and tearing my whole dash apart trying to get to one that's not the problem actuator. Thanks in advance ... This has been driving me nuts for the past 1.5 years in both summer and winter months .

I’m trying to flip that white gear thing so it’ll blow to my face but it’s hard to flip it if anyone has recommendations of an easy way to do it

You sir are the best

Just what i needed to see i wasn't sure what to expect with the 1.5" spacers I'm looking to buy for my 02 tb and now i do thanks.. i had to also change the bolt pattern from the 6x5 to 6x5.5 to fit my escalade rims to it I'm hoping it looks good

Thanks for the information 👍

Thanks Dwaine, I was tired of the knock of death in my Envoy.

Excellent video, Having a hard time finding the Defrost to Floor actuator. Did you replace it? If so can you put the link to the actuator in the comments, Please, Thank you

Thank you! That video is very helpful

thanks for the video

Thank you so much 🎉

How do I know if it’s just the knob that’s broken and not the actuator

I didn't do all that

Thank you for this, it's very helpful!

Video is awesome but you forgot to tell the consumer there's 2 7/16 bolts at 11 o'clock and 1 o'clock to remove

Getchu some tires fella😳

My 08 trailblazer SS dont blow air to the floor is that one ur showing wit out the white the one i need to fix the problem?

My two vents on the drivers side do not work. I need the actuator located right side drivers side to correct the problem. What do I call that actuator when I go to the parts store to purchase it????

OMG...I love the explanation the chevy dealer wanted to charge 100.00 for the part and 5hr labor time @ 160.00 an hour to replace it. I needed to replace the vent to floor 1 did it in about 2 hours

I have a 2008 gmc envoy denali and recently replaced the actuator that controls the air flow to front vents. I watched a million videos on it which none were really helpful .I did learn that with a cordless ratchet preferably extended reach this could be a twenty minute job. Remove the stuff below the steering wheel lay on you back and use the cordless to remove the two screws holding the actuator,unless you have the hands of an infant you are not going to get those screws out without it.

What size are the bolts that hold on the actuators?

Exactly the info I needed. Ty sir. My defrost and floor blow constant and my vents will never switch on

Thank you so much I been trying to find out why my passenger side was always blowing hot are didn't know what one to change

Good tips, I went with bigger tires on my 2004 envoy and have a slight rub, I'll be doing this soon..

So many guy's are making this mistake, Never ever use plastic Manifold Intakes PERIOD! They don't hold up! I have a 1999 F150 4.6 V8. Had intake manifold done over a month ago. Talking to the mechanic, he loves my old manifold Intake, its Aluminum alloy. He hates plastic. He showed me a pile of assorted plastic intake manifolds and he ask me, do I see any metal ones LOL! I had carbon build up, had leaks, it had 213,000 mile on it, when it was done for the first time & runs great.... Enjoy!

Awesum job explaining the functions of each actuator. 2 thumbs straight up n down.

If you have the additional funds, then perhaps but at 300 miles ? If the old manufold was still in good shape, then perhaps I may not move forward unless the truck had 200 miles less IMHO, but I can understand your rationale. All factors have to be considered time, money, and overall engine conditions and miles. I also have the same task to perform on mine. Thx for sharing 👍👍

Did you end up having any shake or vibration?

When I turn defrost on, I hear a loud clicking sound and when I switch back to front or floor mode it stops clicking. Do you think this is the one near the firewall that doesn’t have the white gear showing that’s failed?

Should’ve went with a 2” Lol that’s what I want to do to my 03 TB

I have an O2 ext. I found your video because I'm doing the same spacers, running the same tire size (falken rubitrek at) and the 1.5 looks great. I'm also doing a leveling kit with 2" lift in the front, none in the back. Hope it sits the way I like. My only concern is that I think I should have also gone with a taller tire after seeing your current clearance. Oh well. I do love my trailblazer. Thanks for the video 👍🏼

I changed the battery and now one of the actuators clicks about 100 times every time you start the car . Any ideas?

thanks so much . Great video

You should have done a part 1. To show how big of a problem it is to take the dashboard apart

Thanks for this video, your explanation and repeated words is great. Thanks again.

You're a life saver my man

😅 Brother this is the wisdom key I needed all along I changed the wrong actuator. Thanks a billion

seriously you are the man! now I have to figure out what is wrong with my 02 trailblazer clicks when I start it and it blows in the vents and dash but not always >> Just got the ride so I haven't narrowed it down. what holds the actuators on ? Bolts? screws? its the one with the plastic gear

Why is it such a pain to get the one with the white arm installed? I'm been trying to get it on for 2 days now and still it won't go on. I tried placing the white arm facing either way and still it just won't go on. Only thing I'm doing is getting headaches from being upside down and sweating alot as it's hot outside

Your the only one that actually tells everything. I have been having issues with my envoy not blowing through the front vents. Everyone else said it's the blower resistor which I changed. It fixed the speed (#5 setting) but not the vent then other said it's the blend door actuator which they made out like it was on the same passenger side. I only found the one which is blocked by the bracket. Broke the plastic parts holding it on and still won't come out. I've been trying to cut that bracket off to remove it with little luck. NOW I find your video that shows the exact same resister with the bracket and according to you it's the heat to cold not the doors. 😭 I honestly feel like giving up at this point. Now I have to find the one you said was on the driver side and change it and if that works then I'll have to go back to f8nish removing the other one to try and fix the plastic that I broke which the screws go into to hold the resistor on. I feel like a complete idiot now .

Weird my 03 Silverado doesent have that white gear . It's not broken off or anything it just didn't come with one. The cam that operates the different vent settings doesent have the gear to operate the white gear either. Every chevy I seen on KZbin has that white gear.

To be clarify is that air inlet actuator by the blower motor?? I want to make sure

Wow what a great narrated video. This is the only video of the dozens I've watched that actually explains these horrible designed contraptions. I'm old school as I feel you are too. I replaced the actuator closest to the Floor on drivers side. But I still have air blowing on my feet. Thank you Sir for your time in making this educational and best video . I'm now going back into combat mode to spend more money and time to fix this aggravating problem. God bless

Just so we are all clear dash board removal not required

Informative and to the point. Good job best youtube video on the subject .

So my trailblazer doesnt change vents, stuck on defrost and floor. I need the actuator that has the white arm bracket thing attached to it correct? Any help is appreciated

helped a whole lot brother, thank you

Great video, The actuator that controls the vents, can you replace it without removing the dash? Thanks for the video
