A/C not working? heater control stuck on heat try recalibration

[@jameshus1695]

Add me to the list of "satisfied" customers. I went through the procedure as described on my 2003 Suburban LT and it cured the hot air coming out of the driver's side. Thanks for taking time making and posting this video.

[@VinylVillageGarage]

Glad to help. Gotta love the easy fixes

[@gerrym5299]

2004 Yukon, dual manual controls was blowing hot regardless of control setting. Did this right after I tried to jump start another of my cars that had a slam dead battery. Hmmm... Your QUICK procedure fixed it!! Thanks for taking the time to post this.

[@VinylVillageGarage]

That is awesome, love the easy fixes

[@stevehasty3959]

I had a new 7-way plug installed on my 2014 Silverado and had no drivers side ac after I picked it up. I stumbled upon your video. It worked perfectly. Blowing ice cold again!!

[@VinylVillageGarage]

Glad it helped

[@ronmudie240]

My '04 Avalanche has the rotary dials for each side and I couldn't get the temperature out of the low 60's in Maine in November. This did the trick! Thanks for this great video!

[@VinylVillageGarage]

That’s great. Gotta love that easy fixes.

[@RandyRobinett]

Your video was perfect for my situation. I have a 2012 Avalanche, and needed to recalibrate the AC system - I'm sure it was the Blend Door Actuators... I had tried two or three procedures found on KZbin, but they didn't work. I think because they weren't meant for my exact Avalanche system. Your procedure worked on the first try! Thank you!!!

[@VinylVillageGarage]

That’s fantastic news. Gotta love the easy fixes. Like you noticed it isn’t a one size fits all kind of thing either. The majority of the time it has to be specific to your vehicle. Glad it helped!!

[@CountryDaveAlberta]

This solution worked for me in a 2006 Avalanche. Thanks for posting!

[@VinylVillageGarage]

Fantastic!

[@jordanjones4841]

This tip just helped me with my 2013 GMC Yukon. Thanks man!

[@VinylVillageGarage]

That’s awesome, it quick and simple plus free Glad it worked.

[@americanpatriot2999]

Fuse #39 by itself had no affect. I had to pull four fuses total, including #39, to get the reset. However, it worked like a charm. The ac searched for all actuators, then it blasted me with cold. Excellent.

[@VinylVillageGarage]

That’s great!

[@kevingahan5785]

Worked on my 2010 Suburban! Awesome! Thanks!

[@VinylVillageGarage]

Hey that’s great. It’s a life saver plus free! Glad to help

[@lawrenceworthen4971]

I’ve searched via google and could not find anything to fix my problems. But your video did at least get my air conditioner working again. But I still have the problem that I have to put my manual settings to heat in order to get cold air… 😂 as long as it cools I don’t care which setting I have to use in the Nevada 100+ degree weather.

[@VinylVillageGarage]

You're welcome! Staying cool Arizona is a must.

[@kevingahan5785]

Thanks!

[@VinylVillageGarage]

Welcome

[@patrickjensen7252]

This is great info !! I have to keep my better half happy. I plan to try this technique soon on our 2013 GM a/c.

[@VinylVillageGarage]

I agree keeping the better half happy is a must, glad we could help.

[@paulyoung4145]

2010 silverado work truck. Worked great! Now have heat to clear the plow truck windshield! Never had trouble like this with the old style manual heater controls! Old is better!

[@VinylVillageGarage]

The old stuff had its issues but it was basic enough it could be figured out and repaired at home without a computer

[@JCOmega]

Wow thank you it worked! well my problem was with a 2007 Chevy avalanche, I just changed a dead battery and there was no air coming from the vents, I thought it was the fan motor or that module that's under the glove box, but nope this trick worked!

[@VinylVillageGarage]

Very cool!

[@whitneymckim9651]

Yay! So glad it works now!

[@VinylVillageGarage]

it was a hot ride to Bloomington, glad it’s fixed now

[@romeurei89]

Worked on my 05 Avalanche. It messed up after I replaced the battery! Thanks.

[@VinylVillageGarage]

That’s great, glad it helped out

[@briand7868]

My 2014 gmc Sierra HVAC controls won’t switch from defrost and floor to the dash blowers. Do I have a bad actuator?

[@VinylVillageGarage]

Could be, does everything else work in the heater controls? If so might investigate the actuator and wiring

[@texasdreammaker1]

Thanks ❤ worked 2007 Chevrolet Avalanche

[@VinylVillageGarage]

You're welcome!

[@robertchristman1727]

Well done! Thank you, brother!

[@VinylVillageGarage]

Anytime!!

[@TheBlazer1976]

thanks it worked on mine like a champ 2007

[@VinylVillageGarage]

Awesome! It was a life saver for me plus super easy.

[@JVScustoms]

Any tips or tricks for my 2015 Silverado? Used to have ice cold ac. Now seems like in the morning it will blow cold but will stop blowing cold after a while. One of the passenger side vents blows cooler than the driver side. It has refrigerant in the system. Thx in advance!

[@VinylVillageGarage]

I would check the Freon level. I know when the dual climate control hit the market when it was low you had that problem I can’t say for certain it’s the same on 2015 Silverado but worth investigating

[@JVScustoms]

Yeah I checked it it’s got refrigerant. And the condenser is know to leak on these 14-16 but I’ve already had that replaced when I bought it new. Thanks for your response brother, I’ll keep trying some other stuff I guess

[@VinylVillageGarage]

@@JVScustoms no problem, I did some investigating it seems the Freon level being low can cause a difference in temperature side to side especially on higher heat days on the Silverado. If you don’t find anything else. It’s worth trying an Evac and recharge with the recommended Freon charge.

[@JVScustoms]

@@VinylVillageGarageman thanks for that! Going that extra mile for me, doing research and actually trying to help. Man that says a lot about you my man. I will definitely look into that. My buddy has one of those expensive snap on scan tools I was thinking of seeing if he could calibrate the blend doors with it. He helped me when I had to clean the blade in my throttle body, with it he was able to calibrate the throttle blade and tps sensor. Thanks again man for not just blowing me off. New sub here

[@antoniopadilla8815]

I had to change an vent actuator thinking that would do both passenger and driver side but still I wasn't getting heat, after I did this recalibration process I was able to get heat from the driver side which it was the actuator that I had replaced, now I will change the passenger side one that it's more difficult to do. But thanks for the video. It worked great.

[@VinylVillageGarage]

Glad it helped, when my truck malfunctioned I didn’t know what to do, then I learned how simple a recalibration was and felt it needed to shared.

[@chandlerpetersen1244]

Do you think your problem was just needing calibration or did you actually have a bad actuator?

[@antoniopadilla8815]

@chandlerpetersen1244 Well, after a few days from doing the calibration, it happened again. I can only get heat from one side at the time. So I don't think it is an actuator issue. Now I just live with it like that. If I'm alone in my truck, I crank the heat to the driver side to 90 and put the passenger to 85. This way, I get heat, but if I'm riding with a passenger, I will crank the passenger side to 90 and put the driver side to 85, so the passenger side gets heat...🤷‍♂️.

[@WastelandRonnin]

Thanks for this I just replaced the actuator I'm going to see if this works

[@VinylVillageGarage]

Awesome, I feel it should. Anytime you replace just about any hvac component you will need to do this process

[@ernierackley8906]

Thanks bud... l think this will cure my prob. Really appreciate your video.... Big E

[@VinylVillageGarage]

Awesome, I do like the easy fixes.

[@KUANAJ]

Will this work for the heater as well? my AC blows cold. My heater gives nothing.

[@VinylVillageGarage]

Possibly, it will reset and position things back into their correct locations. So if your blend doors are stuck on cold it will reset them to go to heat

[@Shannon-zn2kc]

So could I use my scan tool to reset as well? Changed my actuator, blower motor, and resistor. Still warm air on passenger

[@VinylVillageGarage]

Not sure, I haven’t tried with a scan tool. Pulling the fuse puts it into learn mode and should work. Unless there is some other fault causing it to calibrate which in turn might set a code that you might be able to get with a scan tool.

[@Shannon-zn2kc]

Thanks! I’ll definitely try your method today and let you know because I see I have 3 fuses that deal with the hvac. I’ll pull all 3

[@Shannon-zn2kc]

So I tried this and now my driver side isn’t blowing heat at all and my passenger side is still blowing cold air. So I might have to try this again. I waited 60 seconds and then waited 2 minutes instead of 1.

[@the_dude111]

Worked! Thank you!

[@VinylVillageGarage]

Awesomeness!

[@zachobrien6239]

Didnt work on my 09 silverado LT 1500 crew cab still cant get it to blow callednafter replacing the controls

[@VinylVillageGarage]

If it won’t calibrate it has to have a part that is not working, it will most likely have set a code in the body control module, if you have a scanner that will do more than just engine codes you could look into that for help. You might have a faulty blend door motor or wiring issue

[@johnnygarcia7436]

thank you it works on my 2010 Tahoe

[@VinylVillageGarage]

Fantastic!!

[@debbiebroughton7701]

Thank you! It worked!

[@VinylVillageGarage]

You're welcome!

[@fayezsaeed655]

it worked for my Escalade 16 😊

[@VinylVillageGarage]

Fantastic

[@ErickODonnell]

Ok I have a question. What does it mean if the ac works without even hitting the ac button? Then sometimes when I'm driving cold air stops and it's nothing but hot air on the driver side only. And if everything is off but the setting is on vents, I can feel air blowing through when I drive. I suspect the module but I'm not to familiar with how everything's set up. Definitely gonna try the fuse though.

[@VinylVillageGarage]

Can’t air I have messed with one with those symptoms. Definitely sounds like the module is malfunctioning internally or loosing power or ground supply randomly

[@ErickODonnell]

@@VinylVillageGarage I did the reset by pulling the fuses and it worked! Air still comes through while I'm driving but I'm able to press the recirculate button, even when everything is off, and it stops the air from coming through. I can live with it this way. Thank you for the help. 👍

[@VinylVillageGarage]

@@ErickODonnell that is awesome

[@ErickODonnell]

@@VinylVillageGarage still blows hot air! 🤬 Turning the truck off then back on fixes it for another day or 2. Now I'm thinking the module is bad. At least I know how to calibrate the new one when I get it.

There might be a calibration procedure for those as well.

Do ya like your avalanche? Any AFM lifter problems?

[@VinylVillageGarage]

Love it actually, 330,000 miles on it now. I did have a lifter failure at 300k miles. Pulled the head and replaced the faulty lifter then purchased the module that plugs into the diagnostic port that turns the afm off and have had no more issues. Plan to keep driving it as long as I can.

[@bikes7777]

@@VinylVillageGarage thanks, glad to hear. I'm going back and forth between the 1stgen and 2nd, due to the afm issue. Will the disabler eliminate that possibility if I install one right away?

[@lopezdad30]

@@bikes7777 I would 100 percent use a disabler right away, they do work! I have a 2008 Avalanche LT and I had my mechanic swap in a fresh motor from GM! I have been using a disabler ever since the swap just to be safe and hopefully avoid ever getting the dreaded stuck lifters. Have put on over 10k miles after swap with zero issues so far.

ha ha ha ha. nice, thanks for watching and catching the details!

[@rgbuckl]

I brought my 2012 Avalanche LTZ in and they charged me nearly $800 to change the actuator. Then I drove it on a trip and it was WORSE than before bringing it there. Noises are much louder and the AC is completely freaking out. I'm going to try this. How has yours held up since posting this video? Any more issues?

Heater and a/c Still works great, 312,000 miles on it now.

Sadly didn't work for my 2011 silverado 2500. Even tried removing all 4 fuses, left fuses off for a couple of minutes, left screen on for 5 mins before pressing any buttons

[@VinylVillageGarage]

Most likely has a part failure, like one of the actuators. Even once repaired it will still need calibrated

[@JL-rg7se]

That is easy enough

[@VinylVillageGarage]

I thought so too
