Froggy I finally had to change out my fresh air recirculation actuator under top dash like your vid. Had epiphany to use small square (1/4 inch), thin, piece of cardboard like holds screws in electrical outlets, switches. This way screw already installed in actuator and no panic to drop screws. Also first tried using blue painters tape however not strong/rigid enough to stay attached. Used 90 degree angle screw/nut driver Right Angle Drill Adapter (Amazon) which helped however had to us liquid gasket maker to glue socket adapter to stay in device. Then used blue tape to hold angle until ready to twist screw. Major patience needed. Thank you for your detailed vid as it really helped!
Thanks for details:)

Awesome helpful video! Thank you Froggy.
Was working on my 2002 Chevy 2500hd duramax.
Watch out for the sharp metal edges, I filled off the sharp edge after the first slice. Used some sticky duct seal to hold the screw for that back one.
In addition I did cut the duct as recommended from another video.
4.5 hours from start to finish and cost $30 for the part, and yes the plastic wheel was cracked in 2 places.
Thank you Froggy! You just saved me a lot of time by explaining the difference between the blend and mode actuators. I will now enjoy replacing just the mode actuator this weekend instead of ripping apart the wrong area of my Suburban.
Glad to help.

Thanks Froggy,
I just went through HELL. replacing the ac clutch on my 2003 Suburban!
I'm hopping actuator are not as big a pain in the arse as getting the C- clip back on holding the electro- magnet!!!!😃😄
Lots & lots of profanity was used!!!! And then there was more profanity!!!😞😞😞
@@jhawkins4412 Good work!
Top notch Froggy. You are a man of many talents. You have helped me with my BMW E36 M3 and now you're helping me with my GMC. I thought it was an animal stuck back there. Thanks for the video!
Glad to help 👍
Thank you for posting this. Been dealing with snow storm after snow storm and today we couldn't turn on the defroster. After watching your video I was able to turn the actuator with a washer and it shifted to defrost. Replacement will happen at a later date when it's a little warmer.
It can be done, follow the video.
:) Post back how it goes so others benefit.
Froggy, great video! I have a 2005 Suburban that is blowing cold air when the heat is on. I was told by the dealership that there are 3 actuators in the dash, I'm assuming they fit the description you gave for your 2002. I have checked the mode, and recirculation ones, all work, so the hot and cold one seems to be the problem. Thanks for the good information. Lewis
This video does help. My mode door is messed up wont go from vent to defroster
You are the only fellow that shows how to remove stuff. I wish that you had to replace the mode actuator instead of that nasty re-circulation motor. The mode door has some tabs that must be carefully removed and NOBODY shows how that comes apart. They all just show it after the fact. It was interesting to see how to dismantle the dash however.
Thanks.
:)
My yukon blows cold air on driver side hot on passenger side the actuator that you're replacing doesn't work at all so it needs replaced but when I manually reach under there and turn that flap than the driver side blows hot air as well am I looking at the right part or should I be looking at something else
K , I have a 2001 suburban that blows cold on driver side and hot on passenger side. It has dual climate control. Can you help me find out what’s wrong?
Thank you for your help.
The AC nor Heat blows thru my dashboard vents, but it blows from the vents near my windshield. I believe that i need to change the MODE ACTUATOR on my 2002 Suburban. Do I find this on the Driver side near the accelerator, or passenger side where my right foot would be, or do I remove the glovebox? Help! I have no AC and due to the cicadas, I can't drive with windows down!!!
It's the white thing right above the actuator mode. You will see it slide up and down when u start car and immediately put on cold air. U can stop it from sliding back down so it dont close. But if u take the HVAC fuse under hood out for 4 min and the ones in the car and make sure it's on auto when u shut the car off and do this. It should recalibrate everything. Mine started when my battery ran out of juice from leaving the interior lights on.
Hi, quick question. I have 02 Chevy Tahoe, my ac stopped blowing cold in the front and still blows cold in the back but only if I leave the front on low the back continues to blow cold air... but I wasted so much money on buying Freon it don’t make sense to me what’s going on. I also had the problem with the deal up under the dash on the driver side it wasn’t moving and was stuck on defrost so my friend turned it to dash so I could have the air blow on me instead of the window anyway can anyone help it’s hot as hell out here in Houston lol I replaced the compressor and ac tensioner pulley already I was told that I may need to change an orfice tube in the line😞
Same issue here did you figure out the problem
Froggy,
At around 7:30 to 8:30, is the camera looking to the right side of the car?
I'm going to be replacing that actuator and plate later today. This is very helpful.
Joel
Lmao Joel
Good question!!!
Good question!!!!
I just replaced mines waited a minute changed the setting and they worked for about 30 seconds then I looked down and the black gear had passed the white gear part anyway I can get it bakc on it doesn’t move when I select the position currently stuck on defrost
Thanks for the help brother
Welcome!
is that mode Acuator control the vents cause my 03 suburban only blows threw the defrost vents
Yes that would be MODE actuator
froggy thanks brother
:)
welcome.
:)
Question, 2004 Silverado mode actuator works and turns when truck is turned on but it won't change when the knob is turned to defrost.
I was hoping to see Froggy actually remove the difficult bolt that holds up the beauty cover you removed to access the bottom actuator
Sorry, you can figure it.
:)
what controls the blend door or the actuator? A module? that sends voltage and receives signal?
I believe that is correct, but I have not tried to troubleshoot a module, just replace.
My AC in my suburban is on. But is not blowing cold. I was told it was the HVAC box. Help please
Yea just fixed mine Sunday 👍🏾
Cool. Pun. haha
Hello, I have a 2003 Suburban LT. Digital controls. My defrost Blower blows Full blast even with Ignition turned off. I have pulled the Fuse under the hood until I can figure out the problem. Any Ideas?
The digital controls are, of course, very different from mine. I would get the obd2 codes to start.
:)
Take the glove box out and it will be on top
How many actuators does it have and where are they located?
Usually 3, under dash.
I have a 2003 Chevy Avalanche. Mine has 4 there's the mode actuator which is on the driver side as seen in the video and there's two in the dash kind of by the air bag and there's another by the glove compartment. You would have to take that bottom cover off to get to it.
Pls help, replaced mode door actuator. Before turning on, do I need to have my settings set a certain way or will it adjust itself. Pls help before I damage another actuator thanks
I have never heard you need the setting any special way b4 turn on.
After you install the new one you should just be able to do the hvac reset and then it recalibrates itself.
THERE IS 4 ACTUATORS NOT 3
❤❤❤
I can not get my mode door working. mode doors manually work by hand AND the actuator turns both directions when plugged in but putting the actuator on the mode doors causes disalignment problems. The actuator over extends or jams or whatever. Again the mode doors themselves can be turned freely by hand so they are not the problem. The problem is getting the actuator lined up properly with the mode doors so that front on the switch is front vents, feet on switch is actually feet, DEF is actually DEF ect....
There may be a "base" position for the door an actuator arm, when you install & I don't know, but try "trial & error". :)
@@1947froggy Interesting. Yeah, I think the actuator may be broken bc it only spins in one direction (towards Defrost), and when it hits the internal stop, it keeps spinning and clicking. So once I get more money, I will buy another and try it. But for now, I figured out how to reach it while I'm driving to push one way, and gonna try tying a string to it to pull it the other way. Lol.
@@MJM750 Please be safe driving. :)
@@1947froggy Yes definitely thank you. On my truck, I can easily reach the actuator while still keeping my eyes on the road so it's a decent fix for now till I can afford to buy another actuator and fumble around with it. I'll let you know how it goes once I install a new actuator. thanks!
Uhhh..i wish I had seen this first..i just replaced the BDA only to find it was not the right actuator.. MAN taking of that last little screw closer to the fire wall..😕
Not easy.
:)
same here
I have a 2004 chevy suburban with dual HVAC and automatic HVAC. It has been making a ticking/knocking sound for awhile and my air will be hot sometimes. I assume it would be the one under the dash? Are there others that would control the heat/air in a suburban with dual controls?
Well, they are all (the servos) under the dash. I am not sure (sorry) how much difference there is with the dual control. The "automatic" part should not make a difference as I believe that would just be a sensor and a circuit board that would control the hot/cold servo.
03-06 is a whole different animal. They went to more computer controlled systems that year.
OPEN UP THE ACTUATOR INSIDE THERE ARE GEARS THE BIGGEST GEAR THAT OPENS THE FLAP WAS CRACKED ON MINE SO THE ACTUATOR WAS JUST SPINNING AN NOT OPENING THE FLAP I PULLED OF TH GEAR PLASTIC WELDED IT PUT IT BACK ON AN WORKED AGAIN IF THAT HELPS ANYONE.
thx
@@1947froggy I was going to buy a new one but figured let me take it apart I can't hurt it an fixed it.
@@Mryiyo209. Love ya bro :)
I have not found 1 video of the replacement of the driver side help
This IS driver side, see the accelerator cable? Watch video again.
:)
Ok I watched again I still see that he points at the actuator on passenger kinda in the middle
@@silent_torseeker7741 The 2nd half of the video (around 6:00) is him working on the driver's side mode actuator.
You couldn’t show it working ? The actuator I mean.
👍🏻
@7:40 ITS ALIVE!!!!
To replace the one on the passenger side is a pain in the ass
Yes.
:)
