04 Trailblazer Front Vent Fix - No A/C - Broken Actuator
Vložit
- čas přidán 2. 08. 2024
- 2004 Chevy Trailblazer with broken front vent actuator.
For some time my trailblazer would not blow air out of the front vents. It is a common problem for this vehicle. The actuator that opens and closes the vents goes bad. In this video I show you how to remove the dash panels, locate the actuator, remove it, and open the vent so that you can feel your a/c as you drive.

God bless you big homie. One extra thing I wanna add for anyone leaving it in there and just turning it; make sure you disconnect the wire harness after it’s opened just in case it decides to reset itself like mine did 🥴
Nice tutorial, thanks for posting! Had PCM reset from dealer and that actuator stopped working on my wife's 04 Trailblazer. It was a pain to get to.
Thank you for the video it’s really well explained step by step on how to fix the problem. I have the same problem myself and now I know what to do 🙏🏼
Great. I appreciate your compliment and I hope you solve your problem. Let me know how it goes!
Thanks, Max and Nicole! My '03 TB has the same problem. If I go that far, I'll probably replace the actuator but at least your method is a great workaround th beat the heat temporarily. Nice instructions!
Thank you for the video, I tried to reach the actuator in my TB but couldn't, you gave me a good way to do it.
Your welcome brother. Glad it helped.
I broke a butter knife halfway down the blade it worked wonderfully to open actuator. Was able to reach it without taking dash panels off, only the bottom panel. Also don't forget to disconnect wire so it don't reset to close. Thanks for video nice temporary fix
Good tips
We worked on our '03 Trailblazer last weekend for this same issue. We couldn't get to the top actuator, so we started the TB, moved the actuator gear with a big screwdriver, then unplugged the wires. No we have in your face vents for A/C without having to replace the actuator, and we can control speed and temp with the control panel.
Thanks for showing the actuators , I turn mine with a small locking pliers and a coin, without removing the actuator, unplugged the connector and that's it, air to the vents again
That's a good idea.
I guess it's kinda randomly asking but do anyone know a good website to watch newly released movies online ?
@Jad Luciano flixportal :D
@Mark Maverick Thanks, signed up and it seems like a nice service :D I really appreciate it!
@Jad Luciano glad I could help =)
Brilliant!! Thank you! I'll be doing this tomorrow!
What size flat head did you use to turn the piece on the actuator?
Have same problem, I took old one out and put new one in but it’s not working. Do I have to put that white wing thing in a certain way or it doesn’t matter?
Thanks Max. Informative.
Can you help me figure out how to get the headrest off? Mine is stuck and the seat belt is locked on it
thanks for your help you just saved my life greetings from chicago
Thank you for showing properly where it’s located with screws and the wiring I thought it was more difficult so I suffered all last summer without a/c just cause I thought it was to difficult
No Problem
Wow fascinating! I was delivering fruit for my job and the AC had to work. One shop replaced the fan clutch. Nothing. Brought to dealer - a week later - and they replaced the fan clutch with a GM part. haha. $1600 and still NO ac. You would think the dealer would know how to fix it. Dang! Now you show the secret of the actuator moving. thanks
It's a common problem too. I hate how dealers love to rip people off.
@@maxandnicole Just got back from driving 350 miles. I forgot to check my condenser again. But when I got up north - I checked the condenser - the hoses - the accumulator - all HOT. haha. So my AC is totally busted. What happened is the dealer did NOT do the PCM update as per the TSB - since it got "cancelled" in 2008 - and so the mechanic wrote, "not sure if the update will improve the HVAC." So then people say - if you don't get the PCM Hvac module update then the fan clutch will bust again. haha. Oh well... tomorrow the dealer promised to give me free labor for redoing the rear differential cover. They claimed to have refilled the fluid - and fix the gasket leak. Since it was still leaking - then I checked the fill plug and of course it's all rust welded and stripped out - rounded out. Oops. So I ordered a new differential cover. Hopefully it will fit.
Going to fix mine this weekend this helps thanks so much
Right on.
Hey thank you so much you fixed my car!
Thanks for the video! I have a 2002 trailblazer with the same problem defrost and vent actuators are both bad was in there and got defrost working but it stopped again. Going back in and doing it your way.
Thats great man. I'm happy this old video is still helpful!
Thanks for the video it help me out with my problem thanks bro 🙏
I'm glad that this helped you.
Is it the one all the way at top in middle
Thnx 4 posting
Your welcome 😁
Una pregunta,no se podría poner el actuador que si funciona por el que no funciona, aunque ya no funcione defrost?
Thank you for the videos and awesome information, I'm having slight the same problem as you ,my front vents are blowing air but the left side (driver) vents blow warm air ,the passenger side vent is cold ,do you suspect its a closed front driver vent thats causing this problem?
I'm gonna tear the whole dash apart anyways and get to the problem!
Is there a way to PREVENT this from happening again, just unplug the wiring from the actuator?
I will follow your advise on my Chevy blazer 2008 for same issue
ES MUY IMPORTANTE, LO Q NOS E SEÑAN EN ESTA APLICACION, GRACIAS Y DIOS LOS BENDIGA POR TODO.
This was definitely a good how to video.my 2002 trail blazer has the same problem.i think I'll give a shot at fixing it.thanks again
Thanks for the video, but I kinda lost you when you said that's the one right there. My question is, how far in the dashboard is it and roughly where is located? Would you say Straight up behind the stereo somewhere? Please help me identify the location. I have this problem.
How many hours did it take to replace it?
man plz advice me
i have the 2004 model
ist came with ac filter
i found no scrow and no filter any were
Dow of globebox take of the globebox in sade up is the airefilter Cabin .
very helpfull thank u so much really enjoyed that goona go do it now thank
This is the best video on this particular problem! Thank you!
Thank you for the comment. I am glad this helped you.
good vid i have an 04 tb. and same prob. ill give a shot love your vids. thanks....
@@chickennugget3232 awesome 😁
Nice Trailblazer you have there! Also that avalanche in front of you looks prety sick!
Thx. You have a good eye...i didn't notice the avalanche, it's not mine tho.
@@maxandnicole You're welcome
Yasssss! Finally in a manner I understand! Thank you so much!
U are welcome!
If the clutch is kicking on and I still have warm air coming out could it still be a fuse or relay
Not likely. If the air is blowing warm then. Check if you have enough refrigerant, you may need to add some.
So I wonder if I go through the trouble to do this and when I restart the car if it goes back closed or something lol idk why mine stopped working and if it's bad or needs reset it just quit blowing air out the vents 1 day and I can't remember if I had unhooked the battery or not lol it may have ran dead but I can't remember
It will not close again. The part is broken. It needs to be replaced.
What about the rear middle ac? This video helped with the front but I lot the back in the process
Great vid my dude. I have an 02 and no air coming out of front vents. Read online somewhere to hop in, turn the ignition but don't start vehicle, wait 2 minutes. Actuators reset themselves in mine and air started blowing through the vents. Might be luck but gets no easier.
Good tip. Hopefully that helps some other people. It didn't work for mine.
I’ll try right now I have this problem
It didn’t work. I heard pops coming from the climate control control area but I guess it’s just broke
@@peytonbreeland468 Yeah sometimes I still hear it clicking but that did seem to work for mine. Sorry to hear it didn't for you.
@@CH-rt8qw nah here’s the funny thing. Now it will only blow out the defrost. As to blowing out the leg vent
Great info. did this & unplugged the actuator and vent works. The problem I'm having is that it resets back to defrost only when the truck is restarted.
Either you got KnightRider or it sounds like you unplugged the wrong actuator
Thanks you very much brother God bless you
Your welcome

I know this is an old tutorial but I'm experiencing the same problem with my Trailblazer, question can you reach the actuator from the top if I remove the dash board or just underneath to turn the valve?.
No, it's gotta be done from underneath. I'd you remove the dash above, there will still be steel in the way
Was wondering if you went to all that trouble why you didn't replace it?
\
Did this, worked for a year, got a new battery and it reset but someone said you can use a flat stick or bar and reach it through the underside of the steering wheel
I have the same problem, can you please tell me what is 30 seconds when you say 7 30 seconds what does the 30 seconds p part mean?
7/32"
Thanks a lot ,, i have a saturn l300 with that problem so im going to try fix it following your instructions (excuse my english its so basic , so i hope you understandme what im writing jaja,) thankyouuuu
Cool, let me know if it works out!
Thanks for sharing. Should NOT have to replace a part OR do all this crap just b/c u replace/disconnect the battery; Mercy. Thanks again - take care.
Man I can’t thank u enough for this video. I watched it 4X’s and red all the comments. I was left in the dark when you fingered the valve to open it. I got the actuator off now I’m not sure how to open it manually. I can barley see much but what exactly am I feeling for???
Your welcome bro, I'm sorry i haven't replied to your comment. I hope you were able to figure it out. In case you haven't, the plastic piece is like a gear, so you need to turn the recieving end where you took off the actuator.
Max and Nicole Thanks for the response. Although I was quite frustrated after taking everything apart and trying to figure out the finally piece, I did turn the gear your speaking of & reinstalled the actuator. Once I turned on the AC & it blew out cool air 🥶I was so excited. I screamed like a won a million dollars. I put everything back together & sold my truck the next day 😁
@@Perfectdancing that's great man. Glad it worked out for you.
Great video!!!! Chevy tried to charge me $1100 dollars to change it
I'm trying to figure out how to fix my temp issue. My vents blow correctly but the right side temp won't go from cold to warm
Same shit, different servo.
Do you think it could be fixed by reaching up from under the dash? Maybe just removing the bottom without taking the entire dash off
I think you may be able to. but It is in a tight spot so it's best to make as much space as possible to work.
"Look up and see one, that's not the one. Look up and there's another one. That's the one".
I love how it explains absolutely nothing as the first one has no desription... which also doesn't describe the other one...
But hilariously... THAT'S THE ONE! EUREKA! Wait... what are we looking at?
Thanks a lot...
Np
Will this blow air through all my front vents after fixing it ?
I have a 07 Tb
Love how simple and easy the trail blazer is Phillips n 10mm sockets most of the time
Exactly. "I'm Rick James b**" lol
@@maxandnicole forget who you thought I was
I’m Rick James bitch
How did you manually turn the valve without taking out the actuator?
I did end up taking the actuator off. But it is possible to turn the metal dial on the outside without removing the actuator. I just didn't have a tool that would fit in the opening.
@@maxandnicole do you recall the part number for the actuator? Also was it the vent actuator?
@@miguelare3 srry, didn't get the part number.
when you removed the vent did you need to disconnect or unscrew anything, or just pulled the vent out? thanks
When you say vent are you referring to the actuator? If so, then yes it needs to be unsrewed. I think. It's been a while.
Did u leave it unplug and did u srew it back
I did screw it back. I also plugged it back in, though it doesn't matter. The piece is no good and won't turn plugged in or not.
my problem too
Thankyou
Welcome
Gracias amigo logre quitar el actuador roto
I drove mine down the interstate outside pressure will push to vent open
Do u have rear vents too ?
No.
I am just wondering if your wife initially was like.. I don't want you doing car repair videos on our channel.. then that video is the one that blows up 😁
Lmao you are funny. Gave me a good laugh.
Did you really need to remove the top dash to reach it?
You should be able to reach the actuator without removing the top dash. At the time, I was also removing the radio. Also, removing the dash gives you a little more working space and light
Yes
Top dash has to be pulled on Silverado
I have a 05 Chevy ext and my ac works fine for the front but in the 2nd and 3rd row they only blow to the feet
I have the same problem but I don’t know 🤷🏼♂️ because I change battery 🔋 trying
Could this be the reason the ac clicks and no air comes out
Thank you so man for posting this I appreciate it so much it solved the issue my blazer is old didn’t want to put money into it appreciate it so much awsome video u made it look so easy I killed myself what a tight area that is in 👍🏻
Yea, it is tight. Glad you got it working tho.
Mine will work on face vents when I pull the fuse for the ac. But doing so, heat is blown not ac
My 03 trailblazer did this after replacing one of the coils !
Mine too! I’m going to try this
I think this happens to most of them when you disconnect the battery.
Q función asecesa piesa
That repair just paid for itself... just sell all them spare parts you pulled... :)
Lolol
"First because it's so hot, i'm parking in the shade and get a beer"...Hey come on, that would be my first priority!
Lol, gotta have your head on straight. Some people just don't know how to prioritize!
@Valentino Ethan I'll have to check it out.
What I ended up doing is the actuator next to the broken one (floor vent actuator) has the same size power plug. Unplug the working actuator plug and plug it into the broken one and it opened the vent door so I unplugged it when it opened, keeping it in the open position and now it blows through the front dash. This however will not work if the actuator itself is damaged/broken.
That is a great idea. Clever.
Damn I thought this was going to be a quick duck but ima have to literally become the mechanic or find one. I’m afraid I won’t know how to put it all back together cause in reality I don’t know what I’ll be doing.
No, you can definitely do it. Once you get started it's not very difficult and it's good experience for you to work on your own car 👍🏻
Thanks so much for making this video! It's been so damn hot wout my blowers working! Tried several times to reset it, wouldn't work😭Watched your video,and boom it worked🙂So just wanted to say thanks for saving me butt tons of $$$🙏🏾🙏🏾🙏🏾💖💖💖
I know the feeling!
Ok so basically I lma just need to take it to a mechanic lmaoo
My reaction after seeing the video😂😂
No! U just have to be mechanically inclined
🤣
Or spend a fraction of the price on tools and just replicate what he did
Don't be intimidated. Once you have your own set of hand tools you can save a lot of money on simple repairs. It is worth it and You can do it!
I'm getting cold out of my passenger side and blowing heat out driver side.. why
Whatever the reason that sounds expensive.
Thanks man but my problem is dash vents always on and have defrost but no floor heat?!
I have The dame isue 2004 trailblazer did you Fox your problem
2004 trailblazer dash vents always work. And defrosy Works Well but. No floor air
@@bertapacheco5936 Not yet but from what J hear it’s an actuator.
The second escrub are very dificult for take of .
You don't need to remove the instrument panel cover, just the kick panel. Saves a lot of unpluging!
How can you explain me please
Eleazar Rosales .....just take off bottom panel under the steering wheel, not the whole top panel. He only took that off cause he was changing the radio too, there’ll be some screws that hold both together but you’ll only pull off the bottom part...
@@jmurguia5831 thank you 👌
@@jmurguia5831 thank you very much .
I fixed my car A/C by myself I just buy the part 60 dollars .my A/C Works good, i never reset anything .thank you 😊
Eleazar Rosales ......glad that worked out for you! 🙌🏽
nice intro, grats!
Thanks
Going to all that trouble why don't you just change the switch????
So I did this but it keeps closing again every time I turn off the car and turn it back on. Once the car is back on its back closed!!!🤷🏽♂️ I used a quarter to turn mine!
I would suggest disconnecting the actuator once you've turned it or replaced the part entirely
@@maxandnicole Yeah I just removed the whole thing. Close it from the top and keep it pushing! Thx bro!👍🏽
You were able to turn it with a quarter? I didn’t take mine off, and tried using a coin (penny, nickel) to turn it, but the coins kept getting cut up. It wasn’t budging for me. Any tips?
@@shawncollins6379 try unplugging the actuator. The power running to it may be causing resistance.
I did exactly this and it didnt work i even put a new one in
What if u need to use your defrost
With this fix, the front vents always remain open. So if you turn on the defrost it will still work but the front vents will be open at the same time. If you want to shut the front vents off, at any time, you have close them with the small dials located next to each vent. Or find a replacement actuator.
Easy as pie
It becomes a problem in the winter time when your defrost no longer works and your windows need defrosting
So your a/c works, got it.
You could replace it but any time your battery is disconnected for repairs - Oops - same problem over again. Just get rid of it! Leave it open and manually close the vents - no problem - like you're doing. thanks
Smart. That's right. This seems to be pretty common.
lmao you are fucking awesome
if I had a fxing dollar for the number of times I've pulled that dash apart I'd have myself 2 trailblazers
I feel you. Lol
But my problem all 4 fron
Mine was also all 4 front. It is probably the same thing.
Front
Did anyone notice that the vent selector was set to the floor. Hmmmm.

Ur funny
