Tried this 3x with my 2005 Tahoe. Blows cold for about 5 sec then hot. What did help immensely is you pointing out the location of the actuator. I started my rig, and the moment it blew cold, I disconnected the actuator from power. Constant cold for now. It is summer in south Texas, so I don't mind it being stuck on cold. Thanks for your video. 👍💯😁
Sounds like I may be having the same issue that you had. My 05 Yukon Denali will blow cool air for about 30 seconds to a minute and then warmer air for a about 30 seconds to a minute and this cycle just repeats. It's like the system can't figure out what it needs to do in order to maintain the set temperature.
I’ve been dealing with this issue for two weeks. Throughout all my searches I finally came across your video. Even my brother, a certified A/C technician, didn’t know this cheat. I applied the technique from your video, and I’m again enjoying a solid cold air flow. With temps being 100* + here in Texas, this has been a life saver. Thanks for sharing this information. 05 Silverado LS Ext cab
Ya there's so many little quirks and secrets to vehicles it's hard for experienced techs to know everything. That's why I like sharing stuff like this because it helps others as I find secrets for cars online myself to help me with things.
Have a 2004 Silverado with the manual controls that started blowing hot air out of the passenger side after I had a new battery installed in it. Performed the recalibration just like in this video and worked like a charm. Thanks!
There are a very special kind of people who by spiritual laws receive and great amount of blessings for the way they give to others YOU ARE ONE OF THOSE. Thanks you helped me twice.
Had this problem in a GMC 2500 years ago. Just happened in my Tahoe today. Thanks for the video. Was a nice refresher on the reset! Worked great! Thanks!
This video was absolutely great. I tried it before buying the accuator. It didn't work at first but I did it 3 times and everything worked like factory original. It may be temporary, as the man stated, but then I'll KNOW that that accuator is really bad and replace it. Great job!
@@AnthonyJ350 I had the same problem and it took three tries, but I also found the slider controls were dirty, so I used a nonresidual silicone to clean them. That may(?) be the cause of the mixed signals.
I used your instructions for my 04 Sierra. Would not change from Defrost to Forward Vents. After the recalibration steps, it now works great. After three years and your video is still helping. Thanks! BTW: '04 Sierra, 300k miles, except for trans, and a few minor fixes, it's all original!
Nice! Ya I think you generation of GM truck is one of the longest lasting out there. There are still so many on the road still and bunch are being used for hard work.
Worked on mine too. Passenger side was hot when the AC was on. Thanks Mr. Anthony. My kids and wife will be happy to NOT be blasted with searing heat from now on...
Thank you, Anthony. i just picked up an 05 silverado lt low miles, clean truck. Being a tech, i had a hunch. There was a reset procedure. Thank you for fund raising for our veterans.
Glad the video helped you out! I'm a big supporter of Veterans in North America. They sacrifice so much and don't have a lot of support, so it's up to us to help out those who protect our countries and way of life.
This also works if your vent is stuck on defrost. It finally worked on my 2004 Chevrolet Silverado 2500 after the 3rd time and I was sure to use my stopwatch on my iPhone for correct wait periods. I could see my actuator going through the recalibration process but after waiting the 15 sec and cranking truck back up it switched back to defrost on first 2 times. The third time was a charm. I left controls on vent for the time being because I’m afraid to change it to anything else at the moment. Will update this comment if it gets stuck back to defrost. Thanks for the video!
Yessir! Also I don’t know if it makes a difference but I flipped my 10A fuse like yours in the video on the 3rd try and it finally worked. Idk if this had anything to do with it but worth a shot if anyone is still having trouble.
Thanks to @AnthonyJ350 I just replaced my AC panel in my 05 Chevy SBSC because the LED’s in the temperature and right side were burned but after installation it was blowing only hot air in the driver side and followed the procedure explained in your video and everything is working perfectly fine now. Really appreciated, I asked to an auto AC tech and he was ready to replace compressor and 3 actuators, thank God I found the video. Kudos man 👊🏼🏆
Very expensive and at least couple days if lucky, your tutorial was less than 5 minutes and everything perfect. The AC Tech sent me a msg today and I replied back with ur video link, so far silence lol 😂
Thank you, it worked for me after replacing my battery! Air power setting on 3 temp controls up on the second mark from the bottom in the blue. Remove 10a HVAC/ECAS fuse in the fuse box under the hood for 2 mins, reinstall it. Start Ignition leave running for 2 mins (DO NOT TOUCH HVAC CONTROLS) Turn igniton off for 15 seconds. Start'er up and test functionality. 💣💥!!
worked for a bit, then went on to full failure mode. Had to replace the actuator (drivers side 2:00 in relation to the gas pedal... easy to see but not easy to work on). fired it up, and thought it wasn't working at first, then I moved the temp knob to 50% and "voila" was greeted with cold refreshing air conditioning on the drivers side again. redid the calibration, and now momma will be happy to ride with me again... it works as advertised. Houston heat and humidity are both great motivators to get this thing working. Once again, I greatly appreciate your posting this.
This worked for me. I had the AC fixed at the dealer and one of the actuators was making a clicking noise. I reset the system and now it works great. Thanks
Dude you are a life saver. I disconnected my party to try and do stereo stuff (didnt have the right parts) put everything together and next morning blowing hot air. I did all that at work and now i have cool air! You rock
Did this yesterday to my 2004 Silverado with the two vertical slide temp controls. I could hear the actuators moving back & forth while it re-calibrated and it seems to have fixed my hot driver side/ cold passenger side issue. Thanks for the video and the link to the Sparkys Answers article!
Thanks for this. I swapped batteries in my trucks 05 and 06 silverado today. The 06 reset first try. The 05 I had to do it 3 times, but finally worked. That 05 is a cranky one to reset. Appreciate your video
Hey guy, I'm not a car mechanic, just a driver. I did electronic work in the past. Just wanted to say thank you for saving me at least $200 or more. The procedure worked like a top.
2004 Silverado 2500 , I changed the actuators and I had issues with mode selection defrost was actually front face vents . So technically backwards . I followed your video instructions and BAM!! Fixed . You Rock sir ! Thank you for making this video .
Thanks for posting this. It worked perfect on my manual control, 2005 Silverado LS. I had the same condition you described. Only heat on the diver side and cold AC on the passenger side. All fixed now.
Had the same problem after having a new battery installed. I disconnected the ground terminal from the battery for about a minute and turned only the ignition on and heard the actuators resetting. After the sound went away, I turned vehicle and AC on and seems like it solved the problem. Thanks for posting!
This procedure worked great for me! After pulling the battery cable to put a new fan motor and resister in I started having troubles with the actuator. I am suprised that as many people I had talked to, nobody had this suggestion. I almost spent $100 on a new one, you tube can be your best friend at times.. Thanks!
Thank you, mechanic changed an actuator recently and he may not have needed to, was only getting hot hair on driver side, no a/c and no fan speed. Did this reset and i now have a/c on driver side and fan speed.
IF you have a friend that has a scanner with bidirectional capability he can go in and go into the scanner and under the GM models you can click a button and it automatically recalibrates all of the actuators at once. It's pretty cool listening to all of them cycle thru at the same time. I know the snap on Solus Edge, Snap On Modis Edge and the ones above it do that was well. There's other cheaper scanners out there that have function as well. You need to make sure the scan tool has bidirectional capabilities though as some scan tools, especially the cheap cheap ones only allow you to only scan codes at look at certain data. Remember always properly diagnose the problem instead of just swapping parts out as a lot of "parts changers" do especially dealerships and shops with inexperienced mechanics do. Understanding how these vehicles operate is a open doorway into fixing alot of your own stuff.
It worked !!! I had some electrical drama fry the resistor harness and resistor. I replaced both and the fan (for good measure) but now it was blowing hot from driver’s side but cold on passenger side (corner one). I was fixing to order new actuators but decided to try this first. Am very thankful this reset worked. (Summer in Alabama. ) Thank you.
Awesome fix. I had the issue after my battery quit and had to be replaced. After installing the new battery, the drivers side was blowing hot. This fixed it completely. Thanks for the video.
That happened to me on 2006 Chevy Silverado 1500 LT, i went to O’ Reilly’s they told me I needed Freon. It’s still didn’t help, my Freon was full. After seeing this video finally I might have a solution to why my truck blows warm/hot air on the driver side only, thx U
mechanic told me i needed 1,000.00 parts and labor,i did the reset and everything works great,after reset, blew all the dust out of vents on its own!! because it is now calibrated. i wish i knew about this sooner.i fought with this problem for 10 years.i would always have to pull over and restart the engine
yes!!,remember i asked you about arc amps. vs. alpine amps. and hybrid audio?? i went with 2 arc xdi 1100.5. ,and alpine pha-800 processor front doors have 7.1 lse HAT and 3.5 lse HAT in each front door,600 watts going to 7.1s,and 150 going to 3.5 all off the pxa-h800.rear doors 6.5 HAT carbons lse and rear pillars 3.5 HATs lse with custom passive crossovers(150 watts) for fill,and 2 jl audio 10w6v3 2004 tahoe SOUNDS GREAT for talk radio!!!! and vin scullys last year!! oh and music.THANKS for your help Scott Welsh did all the advisory!! for install and the audio shoppe in riverside ca. did the install
I replaced my blend door and was still having heat only on driver side, followed your directions here and it works as it should. Thanks for the video, I appreciate it.
Jimmy Cassell Glad it helped! Ya even after change out the actuators you'll need to do the reset procedure. Mine has been great since I made this video.
Awesome video. I have had this similar symptom before and had to replace the part. I followed the steps accordingly in the video and issue was resolved!
I had watched a lot of videos, became convinced I needed to replace the actuator, placed an Amazon order, somehow saw this video that described my problem, followed the procedure and PRESTO, problem solved! I rarely "like" UA-cam videos, but heartily clicked the like button on this one.
@@AnthonyJ350 Hmmmm I may have hope then , replaced the temp actuator which fixed that problem but new actuator for DEF/VENT/HEAT isnt helping soooooooo I will try the reset tomorrow :) fingers crossed !!
It actually took mine about three days to recalibrate but now it's working fine it just blew cold out of my dash for like 2 days and like on the third day I turn the truck on and it all worked fine again so thank you very much
WoW I Thank You Sir for posting this ‘fix’ I just did this on my 2006 GMC Sierra and it reset everything perfect. Like some of the others I disconnected the actuator between the ash tray and glove compartment and I now have cold air both driver and passenger side. Thanks again!!
Worked for me on my 2005 GMC Sierra 1500 by removing the actuator and cleaning grease off of the actuator contacts and re-calibrating per the video instructions . Thank you for the video.
Who are you & where have u been???? I placed the key in the on position, placed the temp hand n d position he said to. Then cranked the car & Bam!!!! Cool Air! Thanks so much!!!!
This worked on my 2001 Silverado 5.3L. Problem was that I wasn't getting good heat. I replaced the blend door with a new one and used this method to calibrate it. I then got a flashlight and moved the temp control from cold to hot slowly and back to cold and could see the blend door moving. So, all looks good! Thanks for the video!
DIDN'T WORK THE FIRST TIME for my '04 Silverado. I did as instructed and the air only came out of the defrost vents along the windshield. When going through the steps the vent select dial was turned full left to the upper vents on the dash. So taking a guess I set the dial to full right to the defrost vents and ran through the rest of the instructions. THAT WORKED!! Thank you this is great now I have full AC blowing out of what ever vents I select. This was done after replacing the blend door actuator, the lowest one down by the center floor vents.
This worked like a charm.... i have the manual dual climate control as well and it was the drivers side only that was giving me the issue, it was blowing a tiny bit warm even when completely set on cold. Before the reset, i removed blend motor(original GM), carefully opened it up, inspected for broken teeth, none to be found, i cleaned the contacts and tracks thoroughly with 91% isopropyl alcohol with a q-tiq. I put it back together and made sure the notch on the shaft lined up with the center mark on the case, lined up the door shaft with the actuator, bolted it in, did the reset procedure and all is well once again, not too shabby for a 17y old part(2005 gmc scsb), luckily all the other actuators are fine.
This also worked for me. Turn on your A/C to the highest blower setting and let it run 5 minutes, then dial up the heat leaving the blower in highest position for five minutes. this should resent your actuator to correctly blow hot or cold.
jose artiga now do I click on the ac cold buttons or recirculate or does it matter? My ac blows cold, artic cold. But if I put on the heater or defroster , it only blows Luke warm .
Have a 2003 Chevy trailblazer the battery was disconnected cause welding had to be done to the rear of the frame. When I got the vehicle back had cold air on the driver side and hot air on the passenger side. I did try the pulling the fuses in the engine compartment first but it did not work so what I did I pulled three AC fuses that were underneath the backseat now everything works like a charm
Great video! Lost prime going down the road and ran my battery down trying to start my truck! My a/c lost its mind! Had to change a fuel filter housing on the side of the road then drive home hot as hell! Did this reset and got me back going! Awesome info!! Thanks!!
Hey bro good video:) I don't know if you seen this but under that 15amp fuse there was supposed to be two more 15amp fuses. Looks like you have a 25amp fuse where there is supposed to be another 15. Hope that helps you bro.
Tried and tried didn’t work, finally took apart the actuator and put back together and it worked for a bit. Decided screw this went to autozone bought a new one, installed and worked like a charm baby!!!
Bro I just tried it Thank You Thank You x1000 I know I saved myself a few bucks, like u said it might b temporary fix but at least I ain’t going home with my windows down in this 94° heat in Houston, TX
Thank you very much worked for mine 2006 Chevy Silverado. Mine was blowing heat on both sides wouldn’t let me control defrost or front and it wouldn’t go cold blower motor would go up and down. Thank you works great.
Just fixed my 06 dmax. zones and temp wasn't working both sides (traditional system/not the auto system). now I have heat, good thing seeing how it's 10 degrees f right now outside. plowed snow with the heat barely working for 14hrs last night. drove it for an hr today with no heat whatsoever. wish I found this vid sooner! thank you man.
Just saved me a mechanic bill. My battery went bad - totally shorted out. And this started happening right after that. Went through the calibration procedure as described and problem solved. Thanks!!!
Kudos to this video. I installed a new actuator and it was not working correct until I followed the steps in this video and then it worked perfect! Thanks!
I had this problem for years, but I could turn off my pickup and turn it back on, and the problem would clear. This worked until recently, then it no longer worked so I put in a new driver's side actuator motor. This fixed the driver's side, but then the passenger side stayed hot. I tried this procedure, and now both sides operate normally.
That's good to hear. I'm doing the cab mounts for the next video with the polyurethane bushings and the hydraulic mounts in the rear. I'm getting a bad creaking noise when I go slow over uneven surfaces.
Vehicle sat and battery was was so low and would not start. charged the battery for a day . Vehicle started but nothing coming out of vents Tried this recalibration and it work great for me. Thanks so, so much.
I have been having this problem with my 2004 Suburban Z71 for over 5 years. I had a bad actuator in the back and Lambs repaired it for $360. Then, I asked about the front one and he said it could be as much as $1000, so I never did it. My HVAC control module was also giving me trouble because when I tried to increase the temp, the numbers would go up and down sporadically. I had to turn the dial very slowly and try to get one number locked at a time. Hard to do when you're freezing and shivering. So, yesterday I bought a new control module and a new driver side HVAC blend door actuator and they arrived from Amazon today. I installed them both (the actuator and the shroud were a serious pain by the center console), and I still had hot air blowing on the driver side while cold air was blowing on the passenger side. I was hoping it was a recalibration effort and not a "remove and adjust and reinstall" type of project. I found your video and it worked perfectly! THANK YOU! My car now works like it is supposed to work. It has been so long. My way of fixing this in the past was to turn the car off while in neutral and restart the car to get the AC to go back on again. First world problem for me solved today and I was cackling like a school girl when it worked. STOKED! Actuator from Dorman: $19 after tax. Saved a ton of $$$.
Henry Rak Part of a dying breed You can always watch someone else. But maybe I talk a lot so people like you can get that FREE advice and understand fully.
AnthonyJ350 no it did not. I solved the problem using a meter and traced the circuit. There was a break in the wire below the fuse box. And, my comment was because you talked more than you showed. Basically I mean you spent way more time describing the fix than showing how to do it.
Henry Rak Part of a dying breed That sounds like a "you" problem. If you read the comments you can see a lot of people are thankful for the fix. If you think you can do a better job by all means make your own video. I find people that make non constructive comments don't have videos of their own for people to criticise and tend to transfer this behaviour into the real world. If you don't like how much I talk, watch someone else.
Tried this it worked for a little while but stared to act up again The door blend actuators at the part store was out outrageous Found one at rock auto for 20 bucks with shipping It’s been working for about two months now fun it’s been working for about two months fine great video
thanks dude i had mine replaced bout 8 months ago changed a dead battery for new 1 and instarted blowing hot drivers side again just from changing the battery ..this worked appreciate it man
My 2001 Silverado was blowing hot air with temp set on cold. I could hear servo motor trying to move to that position, vent position servo was also heard moving. After recalibrated per video instructions cool air blowing! Thanks a million!
Just tried the HVAC reset with my 04 Silverado and worked like a charm. It’s been blowing hot air out of the vents for a month and finally watched this video on it and sure enough it started blowing cold air. Thanks for the info!
Thanks so much man. You earned a sub🤙. Had a date tonight and my 04 avalanche was blowing heat out the passenger side and i live in south Mississippi. We'll se how long it works

That's awesome! Do this next and the truck will last forever ua-cam.com/video/Dql0Uu8-SNk/v-deo.html
Awesome fix. I had the issue after my battery quit and had to be replaced. After installing the new battery, the drivers side was blowing hot. This fixed it completely. Thanks for the video.
Glad to hear it helped someone else!
Was it where if you turn off then on car it works fine then starts the problem a few minutes after
Dude I did a ton of searching and everything went to me just buying new parts. I did this and bam everything’s working again. Thanks man
So glad the video helped you!
That happened to me on 2006 Chevy Silverado 1500 LT, i went to O’ Reilly’s they told me I needed Freon. It’s still didn’t help, my Freon was full. After seeing this video finally I might have a solution to why my truck blows warm/hot air on the driver side only, thx U
Let us know if it works for you
Worked for my 2004 Chevrolet Silverado 2500HD! Totally surprised and saved me trip to the mechanic. Thanks all!
Glad to hear it helped!
mechanic told me i needed 1,000.00 parts and labor,i did the reset and everything works great,after reset, blew all the dust out of vents on its own!! because it is now calibrated. i wish i knew about this sooner.i fought with this problem for 10 years.i would always have to pull over and restart the engine
tim davis Glad it worked! Better late than never right?
yes!!,remember i asked you about arc amps. vs. alpine amps. and hybrid audio?? i went with 2 arc xdi 1100.5. ,and alpine pha-800 processor front doors have 7.1 lse HAT and 3.5 lse HAT in each front door,600 watts going to 7.1s,and 150 going to 3.5 all off the pxa-h800.rear doors 6.5 HAT carbons lse and rear pillars 3.5 HATs lse with custom passive crossovers(150 watts) for fill,and 2 jl audio 10w6v3 2004 tahoe SOUNDS GREAT for talk radio!!!! and vin scullys last year!! oh and music.THANKS for your help Scott Welsh did all the advisory!! for install and the audio shoppe in riverside ca. did the install
Awesome! It's great to hear when people put audio in their vehicles and are super happy after :)
I replaced my blend door and was still having heat only on driver side, followed your directions here and it works as it should. Thanks for the video, I appreciate it.
Jimmy Cassell Glad it helped! Ya even after change out the actuators you'll need to do the reset procedure. Mine has been great since I made this video.
Awesome video. I have had this similar symptom before and had to replace the part. I followed the steps accordingly in the video and issue was resolved!
Awesome, glad to hear it helped!
I had watched a lot of videos, became convinced I needed to replace the actuator, placed an Amazon order, somehow saw this video that described my problem, followed the procedure and PRESTO, problem solved! I rarely "like" UA-cam videos, but heartily clicked the like button on this one.
Glad to hear it helped! Thank you for watching and the like!
@@AnthonyJ350 Hmmmm I may have hope then , replaced the temp actuator which fixed that problem but new actuator for DEF/VENT/HEAT isnt helping soooooooo I will try the reset tomorrow :) fingers crossed !!
@@jerryj3821 Let us know how is goes
@@AnthonyJ350 all fixed :) Im wondering if i got lucky or is lining up the gears critical - just curious - thanks :)
@@jerryj3821 Nice, just needed recalibration
Damn!!! It worked!!! ....passenger side is no longer blowing heat when it should be blowing cold A/C
Nice!
It actually took mine about three days to recalibrate but now it's working fine it just blew cold out of my dash for like 2 days and like on the third day I turn the truck on and it all worked fine again so thank you very much
Great to hear it worked for you!
Thank you so much. This worked the very first time in my 2006 Chevy Silverado!
Nice! Glad to hear it worked!
Thanks 🙏🏽. I watched all kinds of videos on how to change the door but nobody explained that you had to reset it. Awesome video
Glad the video helped you!
Thanks bro! 2003 suburban, was stuck in defrost... Works perfect now
Awesome! Glad to hear it helped!
I have a 2006 1500 4WD, it worked like a charm. Less than five minutes and I had heat again. Thanks!
Glad it worked!
Recalibrated and it worked like a charm, i have the manual controls and was blowing hot on driver side. THANK YOU DUDE!!!
Glad it helped!
WoW I Thank You Sir for posting this ‘fix’ I just did this on my 2006 GMC Sierra and it reset everything perfect. Like some of the others I disconnected the actuator between the ash tray and glove compartment and I now have cold air both driver and passenger side. Thanks again!!
Glad to hear the video helped you 🙂
Worked for me on my 2005 GMC Sierra 1500 by removing the actuator and cleaning grease off of the actuator contacts and re-calibrating per the video instructions . Thank you for the video.
Glad to hear it was able to help you!
Don Heise was it hard getting them off and cleaning them
What did you use to clean them?
Who are you & where have u been???? I placed the key in the on position, placed the temp hand n d position he said to. Then cranked the car & Bam!!!! Cool Air! Thanks so much!!!!
Lol just a guy that likes to work on cars and tries to help people along the way. Glad it worked for you!
I have a 2004 GMC Yukon, and this procedure worked like a charm!! Thank you!!
Glad to hear this worked for you!
Thank you. This worked beautifully. For me the issue was the front. vents were full hot and the back ac was cold. These steps reset the whole system.
Glad to hear it worked for you 🙂
Just did this to pops 03 sierra now it blows cold air! Subbed thanks!
So glad to hear it worked for you!
6 year old video saved my butt, thanks!
Glad the video helped you!
This worked for me, Have to do this every time I put a new battery in Thanks
Awesome to hear!
This worked on my 2001 Silverado 5.3L. Problem was that I wasn't getting good heat. I replaced the blend door with a new one and used this method to calibrate it. I then got a flashlight and moved the temp control from cold to hot slowly and back to cold and could see the blend door moving. So, all looks good! Thanks for the video!
Glad you were able to fix your truck!
Doing this now on my 2000 silverado and the recalibration is not working
You are a saint among Sinners, my good sir. Thank you very much for the detailed video
Glad to hear the video helped!
DIDN'T WORK THE FIRST TIME for my '04 Silverado. I did as instructed and the air only came out of the defrost vents along the windshield. When going through the steps the vent select dial was turned full left to the upper vents on the dash. So taking a guess I set the dial to full right to the defrost vents and ran through the rest of the instructions. THAT WORKED!! Thank you this is great now I have full AC blowing out of what ever vents I select. This was done after replacing the blend door actuator, the lowest one down by the center floor vents.
Thanks for watching!
Thanks for the video Fixed my problem and didn't cost me anything. YES !!!
Glad to hear it worked!
This worked like a charm.... i have the manual dual climate control as well and it was the drivers side only that was giving me the issue, it was blowing a tiny bit warm even when completely set on cold. Before the reset, i removed blend motor(original GM), carefully opened it up, inspected for broken teeth, none to be found, i cleaned the contacts and tracks thoroughly with 91% isopropyl alcohol with a q-tiq. I put it back together and made sure the notch on the shaft lined up with the center mark on the case, lined up the door shaft with the actuator, bolted it in, did the reset procedure and all is well once again, not too shabby for a 17y old part(2005 gmc scsb), luckily all the other actuators are fine.
Glad it worked for you!
This also worked for me. Turn on your A/C to the highest blower setting and let it run 5 minutes, then dial up the heat leaving the blower in highest position for five minutes. this should resent your actuator to correctly blow hot or cold.
are you saying what @AnthonyJ350 suggested worked for you, or just what you describe worked for you or the combination of the two worked for you?
jose artiga now do I click on the ac cold buttons or recirculate or does it matter? My ac blows cold, artic cold. But if I put on the heater or defroster , it only blows Luke warm
.
I replaced my blend door actuator and still didn’t work. I then found this video and it worked. Thanks a lot for this content!! 🙏
So glad to hear it worked for you!
This procedure will also fix a clicking noise coming from the Temp control motor when slide controls are set to full cold.
David Smith Nice!
David Smith usually a clicking means the plastic gear is cracked inside the blend door
Great, because that is what mine is doing.
Have a 2003 Chevy trailblazer the battery was disconnected cause welding had to be done to the rear of the frame. When I got the vehicle back had cold air on the driver side and hot air on the passenger side. I did try the pulling the fuses in the engine compartment first but it did not work so what I did I pulled three AC fuses that were underneath the backseat now everything works like a charm
Thanks for sharing your experience
So pull fuse for one min then reinstall fuse run truck for 2 mins don’t touch controls then shut truck down for 15 sec and restart truck and be good
That's it!
Yup, it should work after
Do I need to Run the engine when putting the key in the on position?
When key is in the “on position” the engine is not running
U leave the key on when you pull the fuse
Great video! Lost prime going down the road and ran my battery down trying to start my truck! My a/c lost its mind! Had to change a fuel filter housing on the side of the road then drive home hot as hell! Did this reset and got me back going! Awesome info!! Thanks!!
Glad to hear the reset procedure worked for you!
Hey bro good video:) I don't know if you seen this but under that 15amp fuse there was supposed to be two more 15amp fuses. Looks like you have a 25amp fuse where there is supposed to be another 15. Hope that helps you bro.
Thanks for pointing that out! Ill look into it.
Good eye, there was a 20 amp in there and it was suppose to be 15. Thanks for pointing that out!
AnthonyJ350 no problem at all:) God bless bro!
4 year old video just saved me a ton of money
So glad to hear the video helped you!
Thank you very much! You prevented a very pissed off girlfriend. 😃
Hahahahaha
I have one of these I’m working on at work, blows hot on on side cold on the other. Going to try this tomorrow morning, your video explained it well!
Let us know how it goes!
@@AnthonyJ350 It worked! Saved the business money, because I didn’t have to get a new part. Great video, and thank you!
@@wiblesgarage2016 So glad to hear it worked for you!
Tried and tried didn’t work, finally took apart the actuator and put back together and it worked for a bit. Decided screw this went to autozone bought a new one, installed and worked like a charm baby!!!
At least you got it fixed :)
This guy's truck is so clean... It looks awesome
Thank You!
Bro I just tried it Thank You Thank You x1000 I know I saved myself a few bucks, like u said it might b temporary fix but at least I ain’t going home with my windows down in this 94° heat in Houston, TX
Glad it helped!
I’ve been battling this issue and replaced the actuator. Still had the problem until I found this video. Thank you so much for the video!
Awesome! Glad you were able to recalibrate the system 🙂
Hey bro thanks so much this video was awesome the reset helped me perfectly at the moment thanks so much again 👊🏻
Glad to hear it helped!
Thank you! I am not mechanical... and, with all of your help, I got it to recalibrate & function. ❤
So glad the video helped you!
thank you, I had to replace the actuator anyways but you do have to do the reset regardless.
Glad it was still able to help you.
Thank you very much worked for mine 2006 Chevy Silverado. Mine was blowing heat on both sides wouldn’t let me control defrost or front and it wouldn’t go cold blower motor would go up and down. Thank you works great.
Glad it helped!
Will this fix the driver side mode selector actuator?
Possibly, did you try it?
Just replace the part/ recalibrate with the step you provided and it worked!! Awesome video! Very informative, thank you sir!
Awesome! Glad to hear the video helped you 🙂
It worked for my 05 chevy suburban 1500 digital controls
Nice! Thanks for sharing!
I tried this on my 2005 Chevy Tahoe. It didn’t work the first time, but it did the 2nd time. Thank you so much!
Yaaaay, glad you got it to work!
Awesome, the best of UA-cam
It worked on my 1995 Tahoe, air goes where I want it to now
Nice!
Just fixed my 06 dmax. zones and temp wasn't working both sides (traditional system/not the auto system). now I have heat, good thing seeing how it's 10 degrees f right now outside. plowed snow with the heat barely working for 14hrs last night. drove it for an hr today with no heat whatsoever. wish I found this vid sooner! thank you man.
Just saved me a mechanic bill. My battery went bad - totally shorted out. And this started happening right after that. Went through the calibration procedure as described and problem solved. Thanks!!!
That's awesome! Glad it helped!
Kudos to this video. I installed a new actuator and it was not working correct until I followed the steps in this video and then it worked perfect! Thanks!
Glad to hear it worked for you 🙂
"Can you help me. On hot mode I have hot air on the passenger side and cool air on drive side. What is the problem. Silverado 2005."
If you figured it out hit me up because I got the same problem
@@titonava4231 did you figure it out?
@@andypace4685 no not yet
Try the procedure again. If it doesn't work the blend motor needs replacement most likely.
I had this problem for years, but I could turn off my pickup and turn it back on, and the problem would clear. This worked until recently, then it no longer worked so I put in a new driver's side actuator motor. This fixed the driver's side, but then the passenger side stayed hot. I tried this procedure, and now both sides operate normally.
Awesome to hear the procedure worked!
Niceeeeeeeee!!!!!!! So far so good!!!!!! THANK YOU!!!! My hero. lol no really!!
Glad to hear it helped!
Got a new battery and had a ac charge he said I needed a switch regulator but I did this and it work thanks 🙏🏿
That's awesome!
No joke, mine just started acting up today.
Martin Gray Let us know if this works.
AnthonyJ350 It has so far
That's good to hear. I'm doing the cab mounts for the next video with the polyurethane bushings and the hydraulic mounts in the rear. I'm getting a bad creaking noise when I go slow over uneven surfaces.
AnthonyJ350 I get that from my extended cab doors
Martin Gray A creaking noise?
Vehicle sat and battery was was so low and would not start. charged the battery for a day . Vehicle started but nothing coming out of vents
Tried this recalibration and it work great for me. Thanks so, so much.
Glad to here it worked for you!
Also REMOVE in cab Fuse " HVAC 1"
I didn't have to do that
I have been having this problem with my 2004 Suburban Z71 for over 5 years. I had a bad actuator in the back and Lambs repaired it for $360. Then, I asked about the front one and he said it could be as much as $1000, so I never did it. My HVAC control module was also giving me trouble because when I tried to increase the temp, the numbers would go up and down sporadically. I had to turn the dial very slowly and try to get one number locked at a time. Hard to do when you're freezing and shivering. So, yesterday I bought a new control module and a new driver side HVAC blend door actuator and they arrived from Amazon today. I installed them both (the actuator and the shroud were a serious pain by the center console), and I still had hot air blowing on the driver side while cold air was blowing on the passenger side. I was hoping it was a recalibration effort and not a "remove and adjust and reinstall" type of project. I found your video and it worked perfectly! THANK YOU! My car now works like it is supposed to work. It has been so long. My way of fixing this in the past was to turn the car off while in neutral and restart the car to get the AC to go back on again. First world problem for me solved today and I was cackling like a school girl when it worked. STOKED! Actuator from Dorman: $19 after tax. Saved a ton of $$$.
Glad the procedure worked for you!
You talk too much
Henry Rak Part of a dying breed You can always watch someone else. But maybe I talk a lot so people like you can get that FREE advice and understand fully.
Henry Rak Part of a dying breed One more question. Did the video solve your problem?
AnthonyJ350 no it did not. I solved the problem using a meter and traced the circuit. There was a break in the wire below the fuse box.
And, my comment was because you talked more than you showed.
Basically I mean you spent way more time describing the fix than showing how to do it.
Henry Rak Part of a dying breed That sounds like a "you" problem. If you read the comments you can see a lot of people are thankful for the fix. If you think you can do a better job by all means make your own video. I find people that make non constructive comments don't have videos of their own for people to criticise and tend to transfer this behaviour into the real world. If you don't like how much I talk, watch someone else.
You are correct anthony; many thanks for the video. Didn't have to "rak" my brain to do it.
Tried this it worked for a little while but stared to act up again The door blend actuators at the part store was out outrageous Found one at rock auto for 20 bucks with shipping It’s been working for about two months now fun it’s been working for about two months fine great video
Did you do the reset procedure after you installed the new actuator?
thanks dude i had mine replaced bout 8 months ago changed a dead battery for new 1 and instarted blowing hot drivers side again just from changing the battery ..this worked appreciate it man
Glad to hear it helped!
My 2001 Silverado was blowing hot air with temp set on cold. I could hear servo motor trying to move to that position, vent position servo was also heard moving. After recalibrated per video instructions cool air blowing! Thanks a million!
That's good to know! I didn't know this would work on the older Silverado. Thank you for sharing 🙂
Thanks Anthony you saved me a lot of money with this reset I was about to start replacing parts till I fixed the problem but now I don’t need too
Awesome!
Just tried the HVAC reset with my 04 Silverado and worked like a charm. It’s been blowing hot air out of the vents for a month and finally watched this video on it and sure enough it started blowing cold air. Thanks for the info!
Glad to hear it helped you!
Was it blowing hot air out of all the vents or just a side?
This fixed my GMC sierra 2005. Heat only on drivers side while on dash. Worked perfectly
Glad to hear it worked!
Thanks so much man. You earned a sub🤙. Had a date tonight and my 04 avalanche was blowing heat out the passenger side and i live in south Mississippi. We'll se how long it works
So glad the video helped you!
