HVAC Automatic Blend Motor Actuator Recalibration Procedure for GM Trucks & SUVS FOR FREE

[@manuelfernandez8198]

I was so convinced by my "A/C" mechanics that it was an actuator or the entire system needing to be replaced. After doing their recommended procedure to disconnect the battery and let it sit for an hour, it would reset. It didn't. After much research on KZbin, came across this and just finished the re calibration procedure. My A/c on both sides work perfectly and now its blowing colder than ever! Thanks so much for the assist!

[@FalconsGarage]

Glad I was able to help!

[@damionbivens634]

How do you do this

[@xusiamez]

@@FalconsGarage Can you explain on a 2001 Yukon. It has the knobs

[@7LilTish9]

​@@xusiamezhave you tried it?

[@ckomck]

I just did this and now my ac is blowing cold on the passenger side after blowing hot for a year. Thank you so much!

[@toyota1968100]

Right on, you’re the man I thought I was gonna have to take it in and take the whole dash out you were spot on. Thanks brother.

[@firstnamelastnameisallowed7943]

I am sure the bulk of you guys have already figured this out but there is one thing that was left out of this video. When you are doing this you need to doit with the driver's door open. When you turn off the key and wait 15 seconds and all those procedures if the door is closed then the HVAC and the radio will stay on as I'm sure you all know. But just incase someone was doing this in a really cold place and had the door closed and was having issues with it I just wanted to point that out is all!! Thanx for sharing this info with everyone, great video!

[@kc2972]

I have a 2004 Yukon. Cold air out of drivers side snd hot out of passengers side. I had just replaced the lower passenger side actuator about 3 months ago so I thought it was defective because I bought it from amazon although it was quiet and not making any kind of noise. The original had stripped its gears and could head the noise. Saw you video and a couple others dealing with this problem. I liked yours better. You explained sequence better and showed exactly what to do. I followed your direction and at the end I had heat on both sides. I could not see any sequencing going on while it was recalibrating like your video showed snd it was quiet so I thought it wasn’t working but after two minutes I turned vehicle off and then restarted and it all worked. Thanks for the excellent video. I definitely did not want to to rip the dash out to replace those hidden actuators. $1000,00 to do that

[@maximusretrievers]

Hey Falcon, I have used your video several times over the last year and a half. I have a 2005 GMC sierra truck. Every once in a while my driver side AC will blow hot air. Each time, I pull up your video, get a refresher, and go through the procedure and I am back in business. Thank you sir for paying it forward. This is an excellent video.

[@FalconsGarage]

Thanks for watching my videos. Not going to lie sometimes I watch my own videos to remember how I did things. 🤷‍♂️🤷‍♂️

[@Cream_CurdlR]

i have the same issue you just described . all i do is stop if im driving shut off the ac , turn off truck for maybe 5 seconds or so.. start back up and it works. but thank you falcons garage for a good hard reboot that may solve other issues. cheers!

[@T.R-NS]

@@FalconsGarageit is resetting, on my 2003 Tahoe, but the air is still warm. It come out cold in the back but it goes from hot and like a lukewarm but not cold. It has antifreeze and coolant.🤷🏾‍♂️

[@T.R-NS]

This is in the front of the truck. But it is resetting but still warm air

[@arhurpereyra1567]

Once again I'm back here to recalibrate my HVAC system. Simple instructions that actually work. Thank you

[@FalconsGarage]

Glad to help!

[@stanleybeckner6417]

The driver's side vents on my dad's 04 2500HD were stuck blowing firey hot air after the batteries going dead, rather than spending $145 for a new blend door actuator I tried this and it worked! Great video!

[@stimmie78]

Replaced all the lights on my hvac controls last night. Took the truck for a drive today and realized it's defaulting to blow only on defrost. Followed your video to let it reset, and I have air going where it should again! Thanks!

[@FalconsGarage]

Glad it helped

[@jerrywillis1363]

Dude... lifesaver! Was all geared up to tear into my dash to fix no heat on passenger side but this fixed it! You’re a rockstar sir!

Glad I could help!

[@joseph03197243]

Did this recalibration on 2007 gmc yukon Denali, there are 3 fuses I pulled hvac-ign, hvac, and Aux hvac rear. Worked perfectly. I was having trouble with rear turning off and front max a/c turning cycling off within a minute of start up. Great info bro, It saved me a lot of headache and time of trying to figure out all the electrical THX

[@FalconsGarage]

Excellent!

[@monacomark9808]

You are the absolute best!!!!!!!! My H2 Actuator was replaced by myself and would turn on for about 15 seconds and then shut off and I couldn’t figure out why until I saw this video. I did everything you said and it worked like a charm. I really appreciate it and your knowledge. Thank you!

[@FalconsGarage]

Glad I was able to help!

[@larryapplegate925]

H2 is that the one that controls where the air comes from ? Mine won’t blow to the face it only goes to the feet or the windshield

[@austinbees]

I can't tell you how much I appreciate this video. I get to drive home in cold ac now. Thanks man!

[@michaelwilliams7050]

Thank you for watching your video I was on my way to the dealership I have a '06 trailblazer EXT with the slide temperature buttons but it still worked out the same as I follow your instructions in all the doors are working thank you

This works too on a 1999 C5 Corvette... Mine stopped working yesterday... Heat coming out of all the vents... then cool on passenger side and heat on drivers side... I checked the coolant all was fine... then I found your video... You are a life saver... now there's ice coming out of all my vents. Thanks for being there!!!

[@FalconsGarage]

Very cool!

[@rickgarcia8572]

[@alicescott8132]

This was great! Thank you! I have a 2004 GMC Seirra that would blow out the defrost. I put the HVAC in auto, turned off truck, pulled HVAC fuse, put fuse in after a minute. started truck and it worked. It didn't go in a recalibration mode that went through all positions like the one here on tour video, but now I could switch it to any position and HVAC worked flawlessly. Thank you again.

[@FalconsGarage]

It's 90F out, and my driver side would only blow full hot because my battery died. Thank you sir! This fixed it. Works on 2012 GMC truck.

[@timothyweiss2219]

I did this caliubration and it totally fixed my issue... which was ... the left (Drivers side) and right (Passenger side) temperature would not syncronize to the drivers side control dial, I always had to turn the dials for both sides up or down. They were acting sepperately. Now the arrows at bottom of temp display are both on and the temp can be controlled for Both sides simultaneously by the one dial ! Thank you for this video !!!

[@scottoakley1135]

Excellent video! Provides hard to find info. Falcon, hope you dont mind me providing the following. Here are the steps in a nutshell, taken from your video: Yukon Blend Door Calibration Procedure Turn ignition to on (not start). Press Auto on HVAC Controls. Turn ignition off. Remove HVAC/ECAS 10A fuse (lower right hand corner fuse box). Wait 1 minute. Replace fuse. Start truck. Screen should show 74 degrees & cycle thru. Wait 2 minutes. Turn ignition off. Wait 15 seconds. Start truck. Test. Should be fixed.

Spot-on fix! 2009 Yukon SLT. Just thought I’d toss the year in there as one of the models this fix will work for.

@Falcon's Garage I can't find the correct fuse on my 2014 Impala Limited. Is see where the fuses are but none of them say hvac. I also don't have the auto button for my ac unit so I figured that part didn't matter. Will disconnecting the battery work? I replaced the actuator and it sounded slower then faster to the point it makes 3 different noises for a span of 2 minutes that sound like an MRI machine. Please help if you can.

But now my rear heat quit working after I unplug the battery all night because I have a parasite drawer in my door lock. I tried to reset a couple more times but no go. Front works fine at 90°.

[@user-fm9kp5gj4d]

Great video. I had a prior problem with my 2004 GMC Sierra drivers side blowing only heat. I replaced the door actuator and it fixed that problem. [I didn't know about the reset procedure so never reset and it worked fine]. I am now having a problem in a/c mode blowing a/c for awhile and then switching to heat by itself. So I performed the reset in this video. The first few times I performed the reset, the fan would only blow through the defrost, and the fan levels wouldn't change. On the third reset, it finally worked. I haven't yet determined whether the reset fixed the a/c heat fluctuation issue (will have to drive awhile to figure that out). I have heard on other forums that my problem could also be the a/c pressure switch going bad (which costs about $20).

Very Good My Man 👌🏻 I been Fighting an 02 Escalade, and after this Proceedure, it has appeared to have fixed my Issue, I either had Flesh Burning Heat, or as soon as you touched the Climate Control, to Reduce Heat, it would go Stone Cold. But I will say, I had to Cylcle it Back and Fourth a Few Times, all the way Cold to All the way Hot, and it Seems MUCH BETTER now, still seems a Little off to me, but it is working now, I do think I'm going to replace the Hot / Cold Blend Actuator, it just Takes too much of the Heat away, but as I said, it does Function now. And also mine has 3 Turn Dials, and the Temp Knob appears to Lock into AUTO as Well ??? 1 thing I would add, is If you Have Rear AC, to Pull BOTH HVAC Fuses, at least I did anyhow, Our Rear AC is Bypassed but there is still a Fuse there, and BOTH OF MINE WAS 30 AMP

Should the vehicle be warmed up first, or can I perform this reset after the vehicle has been sitting for hours or days without running?

no need for warm up the car.
