I was struggling to get heat from my blazer with auto temp controls and this little routine did the trick so a huge thanks and anyone having issues with a GM auto temp system even as old as 1999, try this regardless of the issue because it just might fix it. And save you a trip to the shop.
😂😂istg I'm in a 03 suburban n I'm certified from rooter to the tooter of mine lolww still limping tho lol literally just caught a flat lol but have your shocks separated from the frame from use yet lol
Just tried it on my 03' Hummer H2, and it worked!!! Thank you so much! Haven't had heat on the drivers side in nearly 3 years after a battery replacement! :-)
It’s Saturday and got my battery changed and the AC worked through the defogger and floor but not through the vents. I took to a couple shops and all booked until Monday. Have to use 07 Chevy classic for work Sunday in the San Antonio heat🥵 Thank god I found your video here. All vents working and saved some serious $$$!!! Thanks brother.
can you please help me? seems your issue was simular in a way to mine. I have an 02 avalanche and all my vents work except for the front vents. woud this guys fuse trick possibly make them work again?
Thank you!!! This fixed my GMC 2002 Sierra, I'm getting frigid air now. These type you tube videos are my first stop when I experience issues or questions how to repair things. I appreciate you taking the time to post this video.
Thanks for the video! Battery died in my 2005 Tahoe and when I jump started it the a/c blew hot on the drivers side. I thought I was going to be replacing the actuator, but your easy to follow video helped me fix it!
Thank you very much for taking the time to post this video, it worked on my 2004 Silverado! One weird thing, after those steps it was putting out cool air out the defroster, I was worried and thought I would have to redo it. Then later in the day I restarted the engine and it somehow adjusted and blows perfect cold air....fixed!
My 2005 Tahoe went into theft deterrent mode when I pulled that fuse. Engine would start and immediately shut down on fuel cut off. It was easily reset by locking all doors with auto lock and then key opening the drivers door. Then the climate control reset worked as described. Thanks for sharing this procedure, it sure helped me!
Thank you for making this video I was about to pay a ton of money to the dealer with this video it fixed my passenger side issue I had on my 05 Escalade it stayed on heater only.
2 yrs old video and it's the gift that keeps on giving !!! Thanks sooo much amigo!!! My 03 Yukon a/c was out but after this video we're ready for this South Texas summer... Thanks a million.. Definitely looking forward to more helpful videos!
Thanks for video. My 06 Sierra with auto climate control was either ice cold on 60 or hot as hell on 61+. I even changed temp sensor in headliner. Now after doing what you showed it’s nice and cool still at 67. I was about to have mechanic tear dash out to replace all actuators.
i replaced every sensor and recharged twice , i even bought a new head unit for in the cab! and this shit worked! thank you so much man you saved the day one day before our vacation where its gonna be over 110
This seems to have worked! My truck was sitting for a few months while I did some other work on it, the battery totally died and everything was screwed up. The truck wouldn't even start until I did a hard reset of the system, then the HVAC was still all screwed up. Did this and all seems well now. Thx man!
It worked. Have a 2004 GMC Sierra Truck with the same autotemp setup and center console, not something I was looking forward to disassembling. Turns out I didn't need to because of your video. Thanks for posting the step by step details showing all the areas to go with each step. It behaved exactly as you showed it would and I no longer feel like I'm driving through the Sahara desert on the driver side while the passenger sits in the Arctic.
Tried it on 2003 SuburbaN: Worked great. A couple of years ago had same issue and had to change front control. Your procedure proved succesful. Thanks a lot. Blessings.
Omg! Thank You I’m a grandmother of 4 grandsons and I was going to take them on vacation and needed this video desperately. I’m thankful for Your video & that I took time to really investigate. Oh it’s a 2007 GMC Yukon
Thank you for taking time to made your research about this issue, I had a problem with my 2004 Tahoe, ac air blowing from everywhere but hot air from passenger side. I followed your instruction and fixed the problem in 5 minutes. Thank you for sharing!!!
What a great help…2006 Sierra worked like charm! Can’t imagine time I saved in my life! Live hundred miles from civilization and 20 below zero…nice having heat defrost!!! Thank you
Thank you for taking the time to post this video 5 years ago. You just saved me $200 I would have spent on a new climate control unit. If you have some kind of account like PayPal, etc. posted I would gladly drop a few bucks. Thanks again!
Thank you. On vacation in our 05 Avalanche today when the ac started blowing hot air (summer air). Saw that the compressor was running and dripping water so must have been the ducts. Found your video and worked! It didn’t cycle through the different vents but start blowing cold at the 74 reset. After restarting all the functions still worked. 🤘🏼
Hey man, I just wanted to say thank you! I have an 05 sierra 1500 and after this winter the AC wasn't blowing anymore. I tried these instructions and it worked like a charm!
Excellent! I removed some burned-out light bulbs in my climate control display and, like an idiot, I drove the vehicle without the unit installed. After reinstalling, everything was wonky. I used this re-calibration process and it worked perfectly. And thanks for giving credit as to where you got the information from. Nothing pisses me off more than to watch hijacked videos and the poster acting like it was their idea.
I have a 04 Yukon as my Patrol Vehicle and the AC suddenly went out on a hot Florida Day with no time to go to the garage and grab a spare... Budget cuts are a b$&@$ and there is no money to fix the AC....it has the manual AC setup and yet this still worked!!! Thanks so much!
Wow. Thank you soo much! I was about to go to a shop to have it repaired and just to have someone look it was going to cost me $100. You just saved me from spending possibly hundredth of dollars. Thanks again! You're awesome!
Dude - you probably saved me 300 bucks - was going to take it to the shop - works good now cold when I want cold - heat when the old lady is in the truck
Just tried this on my 04 Sierra and it works perfect again. Thought I was going to be working on the system in the middle of winter but this solved the issues.
Wow thanks for the advice. It just came in handy for my 03 suburban. The rear blew super cold after calibration. The front still not so cold but it definitely worked for the rear.
THANK YOU VERY MUCH FOR YOUR HELP I HAD BEEN TOLD BY SEVERAL MECHANIC THAT THEY WOULD HAVE TO REMOVE THE DASH AND REPLACE THE ACTUATOR AT CONSIDERABLE COST. I HAVE DRIVEN ALL SUMMER IN TEXAS HEAT WITH THE HEAT COMING ON AT VARIOUS TIMES --- THANKS AGAIN !!!!!!!!!!
Kudos! I have a 2010 GMC Delali, and this absolutely fixed the issue I had with my Auto system. Was blowing hot on drivers side and working properly on passenger side. I followed your steps here and it is fixed it so far! Took a few mile test ride adjusting the controls on and off, hot and cold over and over again, and it works! Thanks for saving me a high dollar repair!
I just repaired my A/C automatic blend motor assembly by disassembling the unit, inspected the gears, inspected the large final drive gear and its copper fingers that slide on the variable resistor pad. I put more tension on the copper fingers and used the surplus lube from inside and applied it to the gears. Reinstalled the unit and started my 2012 GMC Sierra with the A/C on, varied the temp setting cold to hot and back again, IT WORKS! Just my time and no parts.
Omg!!! Just did this and it worked on My 2010 Chevy Tahoe, my driver side was putting out cold air, I followed the instructions and now I have heat. I know eventually I will have to replace actuator bit for now I have heat!!!!! Awesome video brother
Dude, you are awesome! For years our 03 Yukon XL only blew hot air when set at 90°. One click down to 89 or any lower and it went to straight cold, no in between. This fixed it! Thanks a million!
Thank You. '03 GMC 2500hd. Had the batteries disconnected for 2 weeks doing injectors. Hvac did not work when I put it back together. You solved it for me. Really appreciate this. Again, thank you
Thank u... I just bought s 04 yukon and changed the battery... ac was hot on driver side... I pulled fused and waited.... I was freaking out... pissed because I just bought it... but thanks to ur vid I'm enjoy cold ac again. Subscribed!
Bro your a life safer it’s currently 12 plus degrees in Texas and my heater stopped working did that and not gona lie thought it was bs but man you came in clutch thank you my man 💪🏼
I didn't know that Jack Osborne worked on ACs! ;) Great info...thanks for the post. FYI: The rear blend door is notorious for breaking. The replacement is expensive and prone to the same problem but one can be made out of steel fairly easily.
Yes, I have contemplated making a manual adjusting arm/knob for the rear, since you really only need H or C. constant tuning seems unnecessary. Would require a hole thru the plastic.
My late 2007 gmc Sierra was blowing hot air out the driver side to vents and ice cold out the passenger side I did what you showed in the video and now I got ice cold on both sides thanks for the video it helped
My 85 year old father in law has a 03 buick regal. Ac works great but no heat, I'm the family fix everything guy so I am definitely gonna try this before replacing the actuators.. Thank you so much for posting this. I will let you know if it works.
Excellent Video.... It happened to me, when I changed the battery, on a GMC Yukon 2005. I did these steps: 1. Turn on the key, ( Not the engine ). 2. Push the A/C Auto button. 3. Wait for controls to reset. 4. Turn off the key 5. Wait one minute. 6. Turn on the Engine. 7. Not touch any A/C controls for two minutes,( let the complete system to recalibrate, You should hear the actuators moving ). 8. After those two minutes, HVAC should be recalibrated. I didn't remove the fuse. Hint: When removing the battery make sure that A/C is on the coldest, so all the actuators are on the lowest setting.
Thanks I just got my truck fixed 👉👍I’m in ny and I neeed the heat thanks to you so simple video you made.very simple and effective 💪🏼👍 you are the man homie
Both a good and helpful presentation. It worked for my two Envoy's. Fuses were located differently than the Yukon but all the same once you get the correct fuse.
I'm setting up to shoot a video on that as well. This same rig has the no rear heat issue. I will show how to temporarily fix without having to spend any money... then show how to replace the defective parts.
2004 YUKON DENALI XL REAR AC WORKS FINE. FRONT AC WARM. WE DID THE BLENDOOR TEST. THE AIR FLOW DID NOT CHANGE. AFTER THE TEST DASH VENTS BLOW WELL BUT NOT COLD. DEFROST LOW FAN NOT COLD. FLOOR NOTHING FOR THE MOST PART IN ANY MODE. GOOD FLOW IN THE MIDDLE VENTS WARM NOT BOILING HOT BUT NOT COLD AT ALL
First, thank you for this helpful tip. I followed along with you step by step. When I started the engine for the second time, the little indicator showed the middle vents and the heater vents. It only showed these for about a half a second and the air only came out of the middle vents. Repeated the process, and for the same result. In your opinion, does that indicate the acutator is bad ? Again, I'm asking your opinion. Thanks again.
Great video ! Question ??? How many blend door actuators are there in a GM Cadillac SRX with automatic dual temp control and where are they ??? Waiting to hear from you 2/20/2020 2: 30 PM ...
Very interesting fix. Would be be helpful if you could copy and paste instructions in the description or a link to the orginal thread. Thanks for sharing.
my 2010 Yukon Denali was blowing hot driver side, cold passenger side; Found 4 fuses labeled HVAC, pull all 4 and waited 1 min, reinstalled and started truck, displayed showed 74 and I let it idle for ~5 mins then hit Auto on dash. Now Blows Hot & Cold when and where it should! Thank you, Thank you!

Great info...thanks for the post.
FYI: The rear blend door is notorious for breaking. The replacement is expensive and prone to the same problem but one can be made out of steel fairly easily.
Yes, I have contemplated making a manual adjusting arm/knob for the rear, since you really only need H or C. constant tuning seems unnecessary. Would require a hole thru the plastic.
THANK YOU FOR TAKING THE TIME IN DETAIL, ONE THING IS I GUESS I PUT THE FUSE BACK ON AFTER 1 TO 2 MIN. BEFORE STARTING THE CAR?
This seems to be working on my 2003 GMC Sierra 2500HD. Thanks for the help!

Right on man! Keep on truckin' my friend
This worked to perfection. Thanks for the step by step directions to reset the HVAC system
I tried this on my 2014 Yukon Denali XL after changing the blower motor module and it worked like a charm. Thanks!
Great detailed description. Appreciate this. Hope it's my issue for Bi_level issue (no vent - floor/defrost only) 👍
Thanks for taking the time to put that out there👍
Came across this gem while trying to fix hot coolant problem in my 04 Sub so I’ll do this while I’m under there! Thank you!
One question...i just bought the actuator...do you have a video on how to install the actuator???
Excellent Video....
It happened to me, when I changed the battery, on a GMC Yukon 2005.
I did these steps:
1. Turn on the key, ( Not the engine ).
2. Push the A/C Auto button.
3. Wait for controls to reset.
4. Turn off the key
5. Wait one minute.
6. Turn on the Engine.
7. Not touch any A/C controls for two minutes,( let the complete system to recalibrate, You should hear the actuators moving ).
8. After those two minutes, HVAC should be recalibrated.
I didn't remove the fuse.
Hint: When removing the battery make sure that A/C is on the coldest, so all the actuators are on the lowest setting.
Awesome video man!!!! This problem has been causing me pain all summer in my 2010 Silverado so glad I found this video
Thanks I just got my truck fixed 👉👍I’m in ny and I neeed the heat thanks to you so simple video you made.very simple and effective 💪🏼👍 you are the man homie
HELL YES MY FRIEND. Did it while I watched. Same results as you. High Five.
Both a good and helpful presentation. It worked for my two Envoy's. Fuses were located differently than the Yukon but all the same once you get the correct fuse.
Bro I saw this like a year ago and never tried it till today thank God u exist brother I'm subscribed
HA! I had to go back and watch it for my son's (same truck) Denali last month because i have no recollection of the process in my brain lol
Thank you for posting this video it worked for my 2004 Tahoe. Perfect step by step.
Thank you so much brother, I have a 2003 GMC Yukon only blowing Hot, saved me so much money. more blessings to you. !!
Worked for me. 05 Cadillac escalade. Was about to put the actuator in, but this fixed it.. good shit. Thank you.
Worked great on an 05 Escalade with the same HVAC panel. Now to tackle the rear system (no heat).
I'm setting up to shoot a video on that as well. This same rig has the no rear heat issue. I will show how to temporarily fix without having to spend any money... then show how to replace the defective parts.
WHAT THE FIX awesome! I would guess it would be manually positioning a door to get the heat only working. Looking forward to it!
ruclips.net/video/LiHQNakCMN4/видео.html That guy did a great trouble shoot on the rear. I'm currently working on that issue myself.
Huge Thankyou, 2003 Denali XL with 200k, these instructions have worked everytime.
Thanks so much for the video! This helped my truck go back to normal operation! Thanks
2004 YUKON DENALI XL REAR AC WORKS FINE. FRONT AC WARM. WE DID THE BLENDOOR TEST. THE AIR FLOW DID NOT CHANGE. AFTER THE TEST DASH VENTS BLOW WELL BUT NOT COLD. DEFROST LOW FAN NOT COLD. FLOOR NOTHING FOR THE MOST PART IN ANY MODE. GOOD FLOW IN THE MIDDLE VENTS WARM NOT BOILING HOT BUT NOT COLD AT ALL
Worked perfectly on 2003 Silverado. THanks
First, thank you for this helpful tip. I followed along with you step by step. When I started the engine for the second time, the little indicator showed the middle vents and the heater vents. It only showed these for about a half a second and the air only came out of the middle vents. Repeated the process, and for the same result. In your opinion, does that indicate the acutator is bad ? Again, I'm asking your opinion. Thanks again.
I would think the acutator is bad, yes.
Does this also reset the rear. I only have hot air blowing in the rear
The most accurate video on RUclips....
Worked for me! 03 Silverado.. Thanks man!
Praise God! Thank you for this video!!! Just did it and it's now running through the recalibration 🙏😎
Great video ! Question ??? How many blend door actuators are there in a GM Cadillac SRX with automatic dual temp control and where are they ??? Waiting to hear from you 2/20/2020 2: 30 PM ...

Very interesting fix. Would be be helpful if you could copy and paste instructions in the description or a link to the orginal thread.
Thanks for sharing.
That’s one of the best videos ever you just saved me some mon not to mention the headache of taking the dash apart it helped mine start working
NIce! Remember the process... It'll likely do it again lol
My AC works great but my heater doesn't and i think it maybe this problem. Will this work with the heating unit as well?
my 2010 Yukon Denali was blowing hot driver side, cold passenger side; Found 4 fuses labeled HVAC, pull all 4 and waited 1 min, reinstalled and started truck, displayed showed 74 and I let it idle for ~5 mins then hit Auto on dash. Now Blows Hot & Cold when and where it should! Thank you, Thank you!
