Suburban 2002 HVAC mode door actuator and blend door actuator location by froggy 

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!

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!

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.

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.

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.

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

Thank you for your help.

Thanks for the help brother

This video does help. My mode door is messed up wont go from vent to defroster

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?

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.

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

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😞

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

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?

Yea just fixed mine Sunday 👍🏾

I was hoping to see Froggy actually remove the difficult bolt that holds up the beauty cover you removed to access the bottom actuator

what controls the blend door or the actuator? A module? that sends voltage and receives signal?

THERE IS 4 ACTUATORS NOT 3

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!!!

Take the glove box out and it will be on top

is that mode Acuator control the vents cause my 03 suburban only blows threw the defrost vents

You couldn’t show it working ? The actuator I mean.

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 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?

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..😕

How many actuators does it have and where are they located?

@7:40 ITS ALIVE!!!!

👍🏻

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.

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....

To replace the one on the passenger side is a pain in the ass

I have not found 1 video of the replacement of the driver side help
