😂😂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
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!
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.
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.
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.
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?
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!
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!
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!
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
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!
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 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.
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
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!
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! 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!!!
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
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 !!!!!!!!!!
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.
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. 🤘🏼
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.
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
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!
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!
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.
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
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.
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!
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!
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!
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.
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
2005 Tahoe. If the interior ever goes dead, follow the parking brake release cable and you may find it leaning against a black box in a galvanized bracket. Move the cable away and everything will work again.
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 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.
Found my 8 yr old Mega Tron dead this morning. Tried using the charger to jump it. Just scrambled the electronics. Replaced the battery, heater controls didn't work. Used your procedure, SUCCESS ! Thanks a million, Man !
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
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 know this video is old but let me tell you did this work, in my case i also had to replace the fuse but Take 5 mins out your day to try it and see if it works for you before you go replacing parts
Thank you very much! This little trick also worked for my 2012 Chevrolet Cruze LT (European model without split A/C). If a Cruze owner sees this: the fuse is in the cabin fuse box, fuse for cabin blower (no. 11 according to manual). A 3 min. waiting time with the ignition on does wonders. You may have to perform the trick several times to calibrate the actuator properly.
I have a 2009 Silverado 1500 Crew Cab with dual climate controls. Had issues with AC blowing hot on driver side, cold on passenger side after battery had died and replaced. Twice. After installing new battery both times, had the AC issue I described above. I tried the HVAC fuse pulling behavior and disconnecting battery cable, waiting a few minutes, then reinstalling fuse/reconnecting cable with no success. Also tried setting the AC to "Auto" with engine on, turning engine off, then turning ignition to "on" (without starting) and waiting 1-2 minutes to initiate OBC calibration, after 1-2 minutes turn ignition to "off", pull the key, open then close driver side door to complete calibration (read that process somewhere on the "interweb"). Nope. Here's what worked for me both times: 1)Start truck, 2)shut AC off completely, turn radio off (you'll need to hear the calibration actually taking place in the dash behind the radio/AC), 3)turn off engine, 4)turn ignition to "on" without starting, 5)touch NOTHING and listen. You will hear very slight electronic circuitry sounds, then (for me) after 3-4 minutes you will hear the actuator doors opening and closing. This took another 1-2 minutes. Then you will hear nothing after about 5-6 minutes. Then wait some more unless you want to do this all over again. 6)turn key to "off", pull it out and exit vehicle (open door, exit and close door). That last part may not be necessary, but I live in Florida, tired of relying on passenger side AC to stay cool, and I didn't' want to take any chances that I screwed this up. I got AC working properly immediately after starting truck.
Brian, you didn't specify if you turned off the main power button or just the AC. I tried it both ways on my 2010 Suburban LTZ and got no response from the actuators after waiting 10 mins each time... any other suggestions are welcomed. the original fix worked like a charm on my 2003 Suburban.
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 💪🏼
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.
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.
The vacuum switch went bad on my 97 S10 p/u. The blend doors wouldn't open all the way at first,then they wouldn't open at all. When the AC is on the fan wouldn't turn on either. It also causes a vacuum leak and the engine will lack power. Evidently this must be a common problem with these trucks because I had to scour the wrecking yard for a switch. I think I found the last one in the yard. Only took about 20-30 min to fix. Running great again.
If the head cap is donned in the reverse fashion by the host - (pre-rally-cap adjustment) - the video has useful content. To the trained eye - it is a key indicator to competence.
Did this twice with no luck. Have already replaced the air controller and 3 of the actuators. Checked the pressure and topped off the freon, still blowing hot, hotter on the passenger side.
I just tried this to check get my rear hvac to blend for heat. No heat in the rear but now my front blower motor vibrates so bad I can feel it in my seat!!! No issues with blower prior to recalibration
The rear is a different animal. Its the blend door actuator on the passenger side in the back under the plastic panel. Speaking of animals... I had a blower motor shake like that before... mouse nest.
Amazing! This worked first try - simply put - awesome!! I have a 2005 Cadillac Escalade that would periodically blow hot air (as in molten hot) , when the AC was running, it was total random. Also, the rear vents in seat rows 2 and 3 would all blow out that same hot air, that problem was ALWAYS , if they were turned on, even if set to 62 coldest AC temp. I live in Florida, so a real problem. This WORKED, took 5 minutes, your directions were perfect. God bless you!
Vehicle: '05 Cadillac ESV. Problem=No blowing of heat or a/c out of front system, but rear worked fine. Problem was resistor. This video was also a big help though. So, if front isn't working for control of pressure, check your resistor. But, you'll do it in this order: Take resistor/blower OUT, test it with 12v power. Then, check your incoming power wire, if it shows 12v, and your blower blows outside of truck using auxillary 12v power, your resistor is shot. Google the part number and pay the $27ish on Amazon, install new resistor, then enjoy working blower motor. Just went through this over this last week, only fixed myself due to shop screwing up, so I dove in and fixed myself. Probably saved a grand in the process, can surely bet they would've replaced blower, resistor, $150 diagnose fee, etc. Stupidly easy fix, but it'll baffle you if you don't know that the blower will blow outside the vehicle with 12v but it won't work while in it.
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!
My 2004 silverado does the heat from the AC ducts on a random basis. I found if I just push the AUTO button, shut off the truck, wait a couple minutes then restart it starts working correctly again.
You may wanna check your cabin filter is your having issues with air not strong enough coming out of the vents, low air from vents usually means your cabin filter is full and dirty and needs to be replaced.
Thanks for the tip, unfortunately it didn't work,,,but while trying your advice and pulling off my fuse box cover I noticed my AC clutch wasn't spinning when the air conditioner was running, I checked to see if it would spin freely by hand and it did, somewhat, so I took a screwdriver handle and gave the front of the clutch a couple lite taps and it took off spinning! 😁 what do you know my cold air started coming out. Lol. 😆 just wanted to say thanks for your advice, it did lead me to the problem I was having.
Everything that can go wrong has gone wrong on my 04 Avalanche. I am now a certified mechanic thanks to GM & CZcams.
My get won't turn on all of sudden usually runs me out .. Blower motor?

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
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!
Huge Thankyou, 2003 Denali XL with 200k, these instructions have worked everytime.
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 know this video is old but let me tell you did this work, in my case i also had to replace the fuse but Take 5 mins out your day to try it and see if it works for you before you go replacing parts
Thank you very much! This little trick also worked for my 2012 Chevrolet Cruze LT (European model without split A/C). If a Cruze owner sees this: the fuse is in the cabin fuse box, fuse for cabin blower (no. 11 according to manual). A 3 min. waiting time with the ignition on does wonders. You may have to perform the trick several times to calibrate the actuator properly.
Awesome video thank you very much for making this!!!
You are amazing, dude it worked. Mine did not say the 74 degrees thing, and didn't cycle through modes but it worked. !
I have a 2009 Silverado 1500 Crew Cab with dual climate controls. Had issues with AC blowing hot on driver side, cold on passenger side after battery had died and replaced. Twice. After installing new battery both times, had the AC issue I described above. I tried the HVAC fuse pulling behavior and disconnecting battery cable, waiting a few minutes, then reinstalling fuse/reconnecting cable with no success. Also tried setting the AC to "Auto" with engine on, turning engine off, then turning ignition to "on" (without starting) and waiting 1-2 minutes to initiate OBC calibration, after 1-2 minutes turn ignition to "off", pull the key, open then close driver side door to complete calibration (read that process somewhere on the "interweb"). Nope. Here's what worked for me both times: 1)Start truck, 2)shut AC off completely, turn radio off (you'll need to hear the calibration actually taking place in the dash behind the radio/AC), 3)turn off engine, 4)turn ignition to "on" without starting, 5)touch NOTHING and listen. You will hear very slight electronic circuitry sounds, then (for me) after 3-4 minutes you will hear the actuator doors opening and closing. This took another 1-2 minutes. Then you will hear nothing after about 5-6 minutes. Then wait some more unless you want to do this all over again. 6)turn key to "off", pull it out and exit vehicle (open door, exit and close door). That last part may not be necessary, but I live in Florida, tired of relying on passenger side AC to stay cool, and I didn't' want to take any chances that I screwed this up. I got AC working properly immediately after starting truck.
I need to pin this! Great info!
Brian, you didn't specify if you turned off the main power button or just the AC. I tried it both ways on my 2010 Suburban LTZ and got no response from the actuators after waiting 10 mins each time...
any other suggestions are welcomed.
the original fix worked like a charm on my 2003 Suburban.
@@johnlewandowski8696 It may reset after several start-restart cycles.
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 💪🏼
Thats great! Been to Texas with snow plows out lol. It gets cold there too!
2005 suburban worked like a champ thank you very much for your time
Thank you , tried it and it fixed my 03 Sierra 1500HD
You got yourself a new subscriber
Right on man! Keep on truckin' my friend
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.
Thank you for posting this video it worked for my 2004 Tahoe. Perfect step by step.
It took me all afternoon, and I had to unhook the negative battery terminal for an hour, but this worked. thank you.
Did you happen to remove the fuse as well?
This worked to perfection. Thanks for the step by step directions to reset the HVAC system
You, sir, just saved me a whole lot of aggravation. Thanks a million.
Right on man! Keep on Truckin'!
Great simple 5 min fix that helped with drivers side blowing cold and passenger side blowing hot on my 05 Suburban thanks
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.
The vacuum switch went bad on my 97 S10 p/u. The blend doors wouldn't open all the way at first,then they wouldn't open at all. When the AC is on the fan wouldn't turn on either. It also causes a vacuum leak and the engine will lack power. Evidently this must be a common problem with these trucks because I had to scour the wrecking yard for a switch. I think I found the last one in the yard. Only took about 20-30 min to fix. Running great again.
If the head cap is donned in the reverse fashion by the host - (pre-rally-cap adjustment) - the video has useful content. To the trained eye - it is a key indicator to competence.
You are the MAN 🤘🏾🤘🏾🤘🏾 2020 This fix worked on my 2004 Yukon Denali. Thanks a million times 😁
Great to hear! Keep on truckin' friend!
Did this twice with no luck. Have already replaced the air controller and 3 of the actuators. Checked the pressure and topped off the freon, still blowing hot, hotter on the passenger side.
Thank you. I don't have this problem but it's good to know what to do if it happens in my Suburban.
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
I just tried this to check get my rear hvac to blend for heat. No heat in the rear but now my front blower motor vibrates so bad I can feel it in my seat!!! No issues with blower prior to recalibration
The rear is a different animal. Its the blend door actuator on the passenger side in the back under the plastic panel. Speaking of animals... I had a blower motor shake like that before... mouse nest.
The most accurate video on CZcams....
Amazing! This worked first try - simply put - awesome!! I have a 2005 Cadillac Escalade that would periodically blow hot air (as in molten hot) , when the AC was running, it was total random. Also, the rear vents in seat rows 2 and 3 would all blow out that same hot air, that problem was ALWAYS , if they were turned on, even if set to 62 coldest AC temp. I live in Florida, so a real problem. This WORKED, took 5 minutes, your directions were perfect. God bless you!
What setting was the rear controll on?
Vehicle: '05 Cadillac ESV. Problem=No blowing of heat or a/c out of front system, but rear worked fine. Problem was resistor. This video was also a big help though. So, if front isn't working for control of pressure, check your resistor. But, you'll do it in this order: Take resistor/blower OUT, test it with 12v power. Then, check your incoming power wire, if it shows 12v, and your blower blows outside of truck using auxillary 12v power, your resistor is shot. Google the part number and pay the $27ish on Amazon, install new resistor, then enjoy working blower motor. Just went through this over this last week, only fixed myself due to shop screwing up, so I dove in and fixed myself. Probably saved a grand in the process, can surely bet they would've replaced blower, resistor, $150 diagnose fee, etc. Stupidly easy fix, but it'll baffle you if you don't know that the blower will blow outside the vehicle with 12v but it won't work while in it.
That is good info! I haven’t had that problem yet but it’s always nice to learn from someone else’s headaches! Thanks for the detailed info
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!
Much appreciated. Fixed the issue with all my heater buttons not working at all.
Worked for me. 05 Cadillac escalade. Was about to put the actuator in, but this fixed it.. good shit. Thank you.
My 2004 silverado does the heat from the AC ducts on a random basis. I found if I just push the AUTO button, shut off the truck, wait a couple minutes then restart it starts working correctly again.
Saved me couple hundred in 7 minutes thanks man 👍🏼
You may wanna check your cabin filter is your having issues with air not strong enough coming out of the vents, low air from vents usually means your cabin filter is full and dirty and needs to be replaced.
Just for your information 07 has the battery on the passenger side and the fuse box is on the passenger side just to add to the confusion
I have 05 Silverado 1500 with manual controls and the fuse removal reset worked perfectly today.
How did you do the manual reset I have same problem
HELL YES MY FRIEND. Did it while I watched. Same results as you. High Five.
Thanks for the tip, unfortunately it didn't work,,,but while trying your advice and pulling off my fuse box cover I noticed my AC clutch wasn't spinning when the air conditioner was running, I checked to see if it would spin freely by hand and it did, somewhat, so I took a screwdriver handle and gave the front of the clutch a couple lite taps and it took off spinning! 😁 what do you know my cold air started coming out. Lol. 😆 just wanted to say thanks for your advice, it did lead me to the problem I was having.
Genius fix! Thanks for sharing the knowledge gained from the gentleman on the forum.
