Here's a short description. The one closest to the gas pedal that's easy to get to, controls WHERE the air comes out. The one buried in the center of the dash controls the HOT/COLD BLEND. The one on the far right down low near the blower housing controls wether or not the system recirculates inside air or brings air in from the outside.
Thanks so much! I used your excellent directions to replace the mode door actuator on my 93 Silverado. Works great! I didn't replace the top screw after all the pain of getting the old one out. It should still hold fine. By the way, I have no mechanical experience, so if I can do it...
Thanks for this video! I only stumbled upon the driver side one the other day, and had no idea what it was. That also means I had no idea about these other ones until your video! I find that the air doesn't blow so well out of the "face" setting, so I may go buy one of these HVAC air door actuators to replace my existing one. My truck is a 98 Sierra SLE which I've owned since 2013, and in that time I've never replaced this, so it's probably failing or going to soon. Thanks again.
Thank you for this. I just bought a 1997 Suburban and it has the exact same issue! I took part of the HVAC system apart to try to narrow down what part it was, and this helps a bunch.
This is the best video I could find on blend door actuators. MJ did a great job of identifying which one does what. Taking them out is another story. I have a 99 Yukon which looks the same. My issue is that the rear air blows cold but not the front. The one on the far right behind the blower works to actuate the door behind the plastic grid (shown in video), as you can see it move when the fan is turned on w/ the a/c on. The actuator turns and the door moves. The one in the middle, which controls temp is very hard to see. I tried to take the lower dash out by removing the 4 screws but something is still holding it in near the lighter area and I can't see if it's moving. The actuator on the drivers side also appears to be working, but not sure if I'm getting full travel. However, all the directional controls seem to work fine. Just can't get a/c to blow cold out the front? I did the reset procedure but still heard clicking after about 8 minutes. I may have some broken teeth on one of the gears? Any ideas appreciated.
Thank you so much! I've been pulling my hair out trying to figure out where this stuff is cause so many forums and other TH-cam videos are calling those two different actuators by the wrong names just confusing the hell out of me as to which one REALLY controls what! Now I know for sure!
Glad it helped, if it is the one below the glove box it is tricky to replace. I will try to find a link to a site that shows tools and techniques to replace that one.
I have a 1996 Yukon and heat comes out of all vents event when everything is OFF. When I turn on then its super hot even on cold settings. Is this also a blend door problem? There are three of them, which one? I hope its not the middle one as it looks impossible to get to? Could it be anything else? Thanks to anybody who can help!!!
Chris, the clicking if it sounds like mine is likely the same issue. It will sometimes work correctly despite the sound. Put your finger on it when it makes noise to verify that's it. It can still work correctly and make that noise.
thank you appreciate the video got a 98 burban shes is something else one thing after the other rear blows front nothing out of the vents driver of course that actuator is done for the one at the lower goes up and down just fine its the one by the glove box I suspect is bad as well since I have to pressure out of front vents and just a little bit of warm air
Thank you very much for this video! I thought I had to remove the entire dash to replace my actuators. As a result, mines been broken for years! I’m overjoyed to know that I can fix my problem, thanks to you. GOD bless you sir!!!
There's 3 actuators Blend Door aka controls the doors to allow air through the ducts it's located to the right of the gas pedal, Temp Mode aka Hot/Cold located underneath the a/c control unit to the right, and last but not least Re-Circulation located on passenger side underneath by the blower motor
hi bud,im getting cold air at the rear & warm air in the front could the issue be a bad actuator or control panel?i have a 99 tahoe & has plenty of freon,thx in advance
So does a 1998 Chevy lumina ls 3.1 have a blend door actuator? How do I know if it's the blend door actuator or the temperature blend door actuator? And if so, is the location of the blend for actuator different from the temperature blend for actuator? There is only cold air coming out on the drivers side vent no matter what the slider control is set at. The passenger side control works fine for regulating the heat and cold. I just replaced the dash heating control unit and still have the same problem. Any suggestions?
Does anyone know if the blend door on the 1995-1998 GMC Yukon can be or needs to be re-calibrated? My modes do work, and there is a change in airflow location, However in vents only mode there is still air coming out from the feet and defrost vents, making vents only feel pretty weak.Thanks for any info!
so if I'm getting minimal heat only on floor vents it means bad blend motor? I get cold air through dash vents even though all the other functions work... such as speed and direction heat dash/defrost etc. etc.
If the click sounds like mine in the video it would likely be that solenoid. Sometimes mine clicked and still functioned correctly. No reason to replace if it's still working right...the difficulty in replacing it is the upper screw that has very bad access. Need to use a 1/4 drive specialty ratchet and apply pressure to the head of the ratchet to keep it on the screw if you know what I mean. A standard 1/4 drive ratchet is too thick at the ratcheting end.
did you ever make a video of how to replace this part? If you did I would love to see it because I need to replace mine and it looks like it's a pain in the rear to get to.
Mine made that clicking sound , it was the actuator for the recirc ( down by the blower motor ), I just made sure it was set to recirc inside air and unplugged the acuator. This would happen everytime I turned the key on or off, I removed blower and verified it was hitting its open or close limit and then clicking.
would the heat still work by unplugging this? dont need ac anyway. would like this annoying sound to stop lol. also its causing passenger side under headlight to flicker
thanks for the video everything on my truck seems to work okay but it still makes a clicking noise underneath that behind the glove box any ideas thanks again
got 96 1500 pickup. can these make noise even if none of the knobs are activated. when i turn key to on i can sometimes hear this sound. not sure which one it is but im thinking by the pedal?
Even when u switch to face it blows out or does nothing mine will blow out on floor when I out it on floor hot or cold whate we I switch it to that works but when it's on either hot or cold and I go from floor to face or defrost it acts like there is something blocking it from coming out
ok I have a 96 k1500 an it blows cold and hot but it only blows out the bottom like it's stuck on defrost n it blows outside by the windshield wipers... could I have something clogging the lines that makes the door flaps open and close
So my question is how many HVAC blend door actuator does a 1996 Chevy suburban 2500 have? Your showing 3 that I can see. How about the rear actuators? Thanks in advance.
I got a 99 Chevy Tahoe & I had my control panel stop working, it won't kick the A/C Compressor on,even since removal of the Control Panel & a friend suggested replacement of a temperature switch I think it is, but regardless before I flush & fill the coolant after an overheating issue may have blown a seal,I put a sealant leak stop in & got it up to temp & it's no longer blowing white smoke out, indicating coolant in engine & oily residue in coolant reservoir & want to flush/fill but want heat working again, esp in cold north & to allow coolant to flow freely through the whole system for flush, to flow through heater core too, but that 1 screw behind the metal bracket on blend door is seemingly impossible to get to, no room to get your hand or a tool in..any ideas. Did you get that blend door on the blower motor out? & if so how in the heck did you do it. I swear the "Flat Head Engineers, are alumni of "ScrewU" ugh, such a pain in the neck!
Do you mean the uppermost screw of the 3? If so get the thinnest head 1/4” drive ratchet you can get and something to wedge against it to keep it on the screw like a long screwdriver and go at it. It has a small swing radius so take breaks to maintain your patience. I believe Autozone has such ratchets, the thickness of the head of the ratchet should be the thinnest you can get.
I get straight hot air no matter what the temperature is on on the bottom doors floor so which one is broke even when the heater is off it still blows hot air all the time please tell me which one it is
I got an interesting one, everything works fine except air will not blow out the defrost vents on the top of the dash. Ive replaced the actuator on the driver side which controls where the air comes out but still won't blow out the defroster it sounds like the flap is blocked.
I have a 1996 Yukon and heat comes out of all vents event when everything is OFF. When I turn on then its super hot even on cold settings. Is this also a blend door problem? There are three of them, which one? I hope its not the middle one as it looks impossible to get to? Could it be anything else? Thanks to anybody who can help!!!
Mine was blowing nice hot hair but now only blows cold no matter what you set the other knobs to. The funny thing is, it also only blows air through defrost vents, but it used to let me change modes. I just installed a car stereo and it stopped working right after I finished. Do you think I damaged the Climate control panel?
that's weird because that's the blend door actuator and I know for a fact mine is bad. Mine doesn't make any sort of clicking or popping and when I turned my heater on I get heat and when I turn my AC on I get ice cold air. The only thing that doesn't work is the max AC. and that's because that motor closes the fresh air door allowing just the air in the cab to be circulated. Now every once in awhile that door will lift up and it'll sound like there's a clogged in the HVAC system but there's no clogged the door isn't being held down by the motor because it's bad.
He is showing the Recirculation Door Actuator under the glove box above the blower motor. I need to replace mine. I can see the one (larger) gold-colored bolt as we can all see in this TH-cam at 2:54. Does ANYONE know if the other two bolts are the same size n type as the one we can see in this video? My hands are too fat and I can not feel the heads of the other two. If I knew what they were, I may be able to get a socket and slim rachet on them. I need help please!
@@MJ-oq1bj Thank you. It turns out one of mine is just a post (by design) and does not have a bolt. So mine has the gold bolt we can all see in your video, the post I can see on my Actuator, and hopefully another bolt the same size that is the super hard to get to one per your response. OK. Got it (I think).
It is bad, do not have a video. You will need a specialty thin head ratchet for the upper screw. That is the only hard one. Used a harbor freight long handled scraper to reach up and leverage against the ratchet head to keep it in place while you unscrew it. Very little swing radius so be prepared to be patient.
@@ThatOh5Cateye might be the flapper is stuck open and is allowing the heater core heat to enter the cab. I have no other info on that but it’s a good place to start. If it’s stuck or the actuator is stuck open then that would possibly do it.
Need one of the thin head 1/4” drive ratchets and torx bit and a screwdriver to put pressure on the head of the ratchet for the upper screw. It’s a small swing radius as well so take breaks to remain calm. Might be a small socket actually, been awhile. Auto zone has the thin ratchet by the registers I believe
Do you have the part number for that actuator. I have been trying to figure out which one that is and this is the only video showing someone taking about that actuator. Good video thank you
I can't be sure then. That actuator switches between the heater core input and the AC input depending upon temp setting. Usually it will stick on one or the other, sometimes it will intermittently stick and then unstick and work correctly.
I been freezing my ass off for 3years an ran a power inverter off my amp wires an put a space heater in my shit but now i have heat in my truck by my truck
Side question, where you have the blank squares shapes like a penis, the bottom two that are side by side, my 97 gmc has a red and green switch. I can’t find out what they are for. Help
Put your socket alone on the hard to reach screw head. Take a long handle pair of pliers and slowly unscrew by grasping the socket.
Pinned it, Well done and thank you!

So what if it’s just blowing hot air whenever the stuff is even turned off.. like really hot air thru the vents.

The popping could be an indication of the same issue. Does the AC blow front and back when you turn it on?
No ac
does not work
I can't be sure then. That actuator switches between the heater core input and the AC input depending upon temp setting. Usually it will stick on one or the other, sometimes it will intermittently stick and then unstick and work correctly.
good stuff
Mines stuck nowhere 😅😅 i have no air anywhere, actuator doesnt move.
HEY WOULD LIKE TO KNOW HOW TO TAKE THE ACTUATOR OFF?I JUST SPENT $700 AND IT STILL BLOWS HOT AIR AND LOW FLOW?
Jerardo Alquisira what was done for that $700.00?
compressor freon and labor
A bad solenoid won't cause low flow as far as I know. I will try to find a link that I saw to replacing that solenoid. Its tricky.
It diverts air to run thru the heater core or ac unit.
