2003 chevrolet trailblazer vent problem 

Bruh. You’re a life saver with this video. I’ve always loved GM SUV’s. It’s all I’ve ever owned. K5’s. Suburban. S10-blazers. This past February I bought my first trailblazer. Found an 03 with 92k on it. Flawless body. Not speck of rust. Solid quarter panels and rockers which is insane for a GM that’s 15+ years old. This thing is the definition of lightly used I absolutely love it it’s been my daily driver the entire year and it’s been absolutely flawless. Last weekend I went to put a new battery on before winter since mine was on it’s last leg. Started it up and click click click click click click click.... It goes off after about 60 seconds but I was looking through the Chiltons manual and I’m sitting here thinking oh my god this is going to be such a pain in the ass to get to I’m gonna have to pull the dash. You totally just saved me a case a beer and Saturday afternoon. Well... maybe not the beer, but the bulk of my afternoon 😂 Thanks a million.

My A/C in my 2007 Trailblazer hasn't worked for about 7 years on the top vents. I finally found you video and I fixed it. No more driving in the Texas Heat Thanks To You. Thank You for the Video!

Thank you! I had the opposite problem, warm air on the drivers side but cold on the passenger. It's winter and my kids were freezing! Well, someone before me must have had the ac problem on the passenger side blowing warm. When I went to disconnect the control unit to turn it manually as you suggested I discovered that it was unplugged. So I plugged it back in and it works fine! Come summer time I may have to disconnect it again..... Thanks again for posting this video. Me and especially my kids are happy and warm now.

Last night I replaced the ac blower motor resistor and I followed your move by disconnecting the blend door actuator and used a ratchet wrench to turn the dial to open the front vents. I had this problem for over a year and never thought how simple it would be to just bypass the fancy operation and just close the vents on the dash if I don't want the air on my face? Thanks for the video, papa.

Same problem here. Was looking for a quick easy fix found it here. Thanks

Thanks bro you saved me $400 👍 Now I need a video on "how to put everything back together"

I always seem to forget which actuator does what, and this was the best video that explains that. Thanks for you help sir!

BRO!!!! THANK YOU SO MUCH!!!!! I changed the wrong freaking actuator at first!!! Thanks to this, I changed the correct one and everything works now. Thank you!!!!!!!!!!

My wife's has the 2 in the back and the top in the front that we are fixing to do here soon thank you for the pointers that helped a lot

i just did the tutorial for my 06 chevy trailblazer and it actually work thank u so much for this video today is so hot and humid glad to have my front vent open and functional but instead of using a screwdriver to turn the actuator i used a needle nose plier and a quarter thanks again

thanks saved me a ton, I was having issues since buying this used truck. now i have heat out of the front vents. Thank you again

Thanks bro it's really useful, I have exactly same problem with my 2009 Blazer

awesome man thanks! didnt have the right tools so i used some needle nose pliers to get the panel off then actually just reached up and unplugged the actuator was having some trouble turning the door but so i used a nickle lol and it fit perfect and was simple to turn thanks for the video man helpled tremendously

Thanks for the video. I just found it, went outside and in no time had the a/c blowing through the dash vents again. Instead of just the defrost/floor only vents. I have a 2008 Trailblazer

A huge thanks for your video. We were able to rig our AC until we can afford the part to properly repair it.

Best one yet thank you for explaining which ones do what!!!!

1 of the best how to videos for Trailblazer AC/Defrost fix bro! my Trailblazer SS has this problem and i need to fix it before summertime here in Las Vegas. cause fuck that with no AC in the summer here lol...all of my shit works in the TBSS except no air coming out in the vents. i just need to switch it manually like you did in the video and call it the day.

Very appreciative of you taking the time to post this video! I saw some negative comments from people that were undeserved. I do not see anyone else taking their time to try and help :) Thanks again!!

Thanks Papa, you answered a question to my problem that was 2 years old.

Best vid about this trailblazer problem

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.

Thank you soooooooo much, very helpful and saved me like 60 bucks...just for the part...totally works...on a 2002 trailblazer...!!!!! Thanks again

Thanks a lot. This really helped; I was able to replace the actuator, even with the tight space but I did it. Now it works good. Saved a lot of money.

Thanks for the info just did it on my 02 trailblazer worked like a charm.

Thank you my friend, you are a great man taking time to show the fix!

Good lookin out homie! Although this did not work for mine (only bc the actuator was so seized up) I just took the actuator off itself and turned the lever by hand. Worked like a charm. Back to blowin snowballs ❄❄❄🌬 Thanks!

It’s 2018... I’m going through his right now, so thank you very much.

thank you woke up this morning to that same problem saved me a lot of timer !! jd

Thank you man saved me a trip to the mechanic

Thanks for doing this video, cut out a lot of the guess work with source of the issue and where the actuators are. Thanks again

Awesome MacGyver fix! I'll check my actuators.

Hey thanks for the video, I was having the same problem. I followed your instructions, and now my AC is blowing good through the vents.

Thanks bro! Your video really helped. You actually explained where and how to fix it unlike ither videos lol thanks bro

i appreciate your video. you did how ever not understand what you were talking about, also the problem is not "fixed". it sounds like you were close to fixing it maybe. you were not clear on what your problem was. the actuators open and close flaps that either block air flow and/or redirect it. you got up close with your camera and a light and that was pretty awesome. thanks

Thanks so much very little information on the common problem good video 👍

They are 15-25 dollar parts online. They default to defrost for a reson...so you can keep your windshield clear....fogging, ice etc. The only added steps once you get to this point is unhooking the wire harness amd removing 2 screws

I have this problem on a GMC Envoy and it should be the same thank you very much!!!

just fixed another one, same problem, thank you so much for this video bro!

Thanks bro poor man has poor ways. This is the best video ever.

Thank you for this video cause i had no idea why i only had one side actually working

thank you very much for posting this video!! it helped me find the solution to my problem, !!!

Trail blazers are great 4x4's the drive trains beefed up and all motor options can put out 300k mi with 0 issue as long as you treat it right . but the electrical (and Components) is a joke on my 06 Ls there's been over 5 recalls and multi maintenance repairs done at home . I'm currently getting ready to hand the truck down to my teenage son and have been repairing every little thing . great video bro

Bro this helped a lot, im having this exact issue. It makes an annoying clicking sound for a while then just stops, but no air to the front vent

Thank You So Very much Bro. So much trouble with mine, now I know.

Good stuff.. thanks! Had this problem for years.

going to try this later today, hope it's as easy as your video makes it look. Thanks!!

Very informative video. It should work to resolve my issue. However, you did fail to mention a few key points. 1) you need metric tools to remove the panel and the wire bundles attached to it, 2) that lower blower vent you moved has a wire attached to it (at least mine did) so don't get crazy when tugging on it to get it out of the way, 3) you need to be a double jointed, skinny armed, oompa loompa to get you hand up in there to turn the little knob. Now let me go track down some scrawny kid that can get his hand up there, after I get a metric socket set.

Great video and information !!! Thank You and GOD Bless !

Thanks. That is exactly my problem. I will try your no money fix it because I too just want air through the dash vents. Hope it goes well.

Thank u so much for the video bro!

Dude thanks. Just bought a used envoy with this problem and I'm gonna do the same cause I live in Florida and no need for heat got plenty.

bro I am living in PUERTO RICO, 2005 gmc envoy slt 4.2 i6 dual climate control, right side mixer door stuck wide open , left ice cold , I did like you suggested, but 1st I unplugged to make sure it was right actuator , air went to defrost and to floor with blend door actuator unplugged , jammed a screwdriver in turned , heard it close , man my car is in Puerto Rico, we don't need no stinking heat Down hear. I wish I could shoot a few pics to you to add , but it would have been a 200 plus parts job to have someone do , and I would have changed actuator , but screw it , lol it works , and did not cost me anything .

thank you man ive been searching everywhere for this answer keep up the good work

thanks for the video. it help me solve the problem. again thank you.

Very helpful bro! Preciate tha time u took to make this video! Good lookin out homie 💯

Nice. Thank you for your time. Mine is an '06 but this applies.

Thanks for the information

Ppl please purchase a laser pointer pen when trying to give detailed information. They are very cheap & Dollar Tree stores even have these now! Thanks for the video by the way!!

Thanks so much for your video...my folks are doing it right now as im typing lol I have a 02 trailblazer... Hopefully it works for me 🤞🤞🤞

Thank you very much. Now my cmpressor went out..

Excellent support video my friend. This is the true meaning of making America Great Again. Helping each other as Christians suppose to do without asking for anything in return. Kudos!!

thanks for the time to upload this ot helped me alot.

Thanks much - repair shop told me $700 to fix this! I can do it for free! Gracias

I had the same issue with an 03 Trailblazer. I replaced the actuator that you disconnected. It cost me around $62 for the part.

Thanks man, that is really helpful!

awesome - showing us the actuator! thanks

thanks bro

great video man. thank you for posting it. I had the same issue.

Thx bro u jus saved me money!

This really helps alot thank you

Thank you for uploading this

I would buy you a beer!!! Been screwing with this for days

Good video bro very helpful keep it up

Worked great thanks so much

This is very helpful but can you explain to me how you removed the floor vent

Excellent.. Thanks for the upload...

good lookin out im having that problem and i was gonna pay for it. im gonna do this myself. sweet video

thanks a lot man ,good video save me some money

Good info. Thank you!

great video, but how do you remove the little plate you taping on.

Is this the reason why no air blowing out across the top vents?

I wish you would have made a video of how you put a screwdriver on there and turned it because we are struggling to turn that SOB.

If the actuator was working before you disconnected the battery and was not working after you reconnected your battery, then the problem could be a reset. 1.) Disconnect the battery again. 2.) Reconnect the battery. 3.) Turn the key on without starting the car and leave it in the on position for 90 seconds to 120 seconds. This will allow the computer to relearn it's settings. If this doesn't work then replace the actuator.

Thanks for sharing. Should NOT have to replace a part OR do all this crap just b/c u replace/disconnect the battery; Mercy. Is there a way to PREVENT this from happening again, just unplug the wiring to the actuator? Thanks again - take care.

On the passenger side you have to remove the bracket in order to see the bolt and to remove it.

It's not as fuck right now and my truck is stuck in heater mode lol no bueno but this'll get it fixed till I figure out a more permanent solution 😆 thanks!

Nice video, good job.

Great Job!!!

I took mine to pep boys to get the AC condenser replaced. All my vented worked perfectly until I got the trailblazer back. QUESTION .... would that cause the vents not to work?

Will try and thanks

thanks. that helped me out

My problem is my car battery went dead and when I replaced it all it does is blow air through the defrost and for about 30 seconds there is a loud clicking noise coming from under the dashboard any thoughts would be appreciated

very helpful !!!!!!!!!!!!!!!!

thanks for the vid bro!

Thanks bruh.

I understand it common that once. The power. Is lost. And. Reapply that the computer resets them by slamming them closed which tend to break them .

Thanks bro that helped

was very helpful thanks but I think I just will buy another one...:)

You have to reset you Climate Control system. If you disconnect your battery and do not allow 2minutes for the Climate Control to recalibrate itself, and adjust the controls before the calibration completes. Then you will brick or freeze your system where ever it is. You must re-disconnect the battery and the fuse. Wait 2minutes and reconnect everything and try to allow the truck to recalibrate itself without touching anything. Or take it to the dealer and have them reset it with a Tech-2 scanner.

Im trying to do what you did but im having a bad time trying to turn the metal thing.
