Man I appreciate this video I fixed my heat problem just by watching. The crazy part is I took my truck to two different mechanics one told me he had to take my dash apart and the other one charged me for a thermostat🤬. But I watched your video and fixed it myself. Thanks a lot
kingb - Same here. I was told thermostat, heater core, etc.. It is amazing how uneducated most mechanics are about their business. CZcams is smarter than most of them.
This video just saved me alot of trouble in locating this actuator.. Many thanks man! I actually found that there was nothing wrong with my actuator.. My daughter sits in the middle and the cover didn't come with the truck when I had bought it. My daughter accidentally unplugged the power to the actuator preventing it from working and thus is why I had hot air! :-p
finally i found a video with the exact same truck. thank you

Thank you for the video. I know it's been awhile but do you remember the size of the actuator's bolts? I saw in another video that they take a 5.5 millimeter socket.
Thank you my brotha! I actually lost all heat in my Avalanche and froze my ass off for a few days here in Washington right when it started freezing out! Your video was like a map to a campfire🔥
Glad it helped!!
Hoping this helps me too just found out this fine December morning that even after heating up the truck AND driving around, the “heater” still feels like it’s blowing nothing but ac at me
Hey man I just wanted to say thank you I have a 01 2500 and this was my problem I tried everything and then I came across your video where you explain how to manually switch the door I did that and it became very cold now I know what it is and I wanted to thank you!!
I have a question. I saw this video and watched you plug it in and watched the actuator move both left and right. I just bought one for my truck (I have a 02 GMC Sierra so it's the same set up) and did the same thing, but it only moves in one direction.. towards the heat. Does that mean it's a bad actuator or a bad control module at the dash? How do you check to see if the Control Module isn't working the way it should? Because I can switch it to hot and cold, but only goes to hot. The actuator doesn't even attempt to go to the other direction. Any help would be great. Thanks
Great video but I have a question I replaced the actuator but before I replaced it I worked it manually and still no operation through the vents just blows trough the defroster manually operated.
@Cody the Car Guy I have a 05 Suburban with heat blowing from the passenger side. I purchased Dorman 604-106 as directed by 1a Auto. All other vents blow cold. Am I looking at replacing 2 different actuators or just the one over the hump?
Thanks bud solved my problem have AC again now
Awesome video, straight to the point. My old actuator was broken. Then replaced with a new 1. Tried testing like u did and it don't move on actuator. Any suggestions. 2000 silverado here
A mechanic charged me $920 for this repair a few years ago. He said they had to "remove most of the AC from under the hood to access to the pneumatic actuator". This was on a 1999 GMC Sierra. I hated spending the month, but I needed AC in Phoenix heat in July.
if your heat was staying on no matter what, then your blend door was stuck open. and in my comment above, i mention it. but the blend door, not mode door which is what this video explains, is near the heatercore hoses and does requires removal of a lot of stuff to access, and is very labor intensive and time consuming
Hi Cody, I know this is an older post, but I have the 99 new stye Silverado and i'm getting that clicking noise from the actuator that lets fresh air in. Do you have a video for that one? Thanks
Would this be the same on a 1999 new body style Silverado?
Thanks for the video...👍
Good video. Except I would not rely on the part# given. Dorman 604-112 and 604-106 as an example will all fit and are all identical. They are model specific. Best to pull out part, cross reference the part # on the actuator to the Dorman by simply typing in the part # on the part itself into a google search.
I have a 1999/2000 the first year of the new body style which looks like this. How do I know if I have one or two of the control actuator mine or not.
What is that bolt called ? I'm missing the fitted peace that turns
So temperature control module, blend door actuator are the same?
I replaced this actuator, but when it gets below freezing it won't switch to defrost or full floor heat. I could turn the peg and operate the door so I don't think it's sticking. Any ideas?
Thanks for the information how to replace the part
Size of the bolt head might be helpful 5.5 mm I believe is what it is
that changes heat to ac. what changes defrost to vent?
Need to find blend door actuator on 2000 chevy express 1500 van
I’m replacing the heater core on my truck so I may as well replace the blend doors too.
On the money....many thanks.
Thank yoooooooooooooooou!!!!
What do I do if I can’t turn it by hand it’s stuck
Thanks, got the actuator changed out, the old one was defective, but did not fix the problem, can't get heat! How do you change out the worn-out
/broken door assembly? The caption on this video was Blend door location and replacement, but the actuator was shown? It appears to be really hard. My truck is a 2000 Silverado high milage. Can you help?
georgiamudslinger
Thanks so much
Ok I am not entirely sure if my issue is the same, I am thinking not. My issue is I can't get my truck to change which vents its blowing out of. When I move it from floor, to midvents, to defrost it doesn't change, is this the part I need to replace? Never mind figured out its the Mode Selector Actuator, sounds not as easy as this though, lol.
Thanks for the information I have the same problem
any idea how gm ships the new blend door acuator mine went out and only works in defrost and floor but trying to figure out which position to put my switch at floor or defrost or face ???
can that flap get jammed? And
Very helpful video! I'm trying to fix my ol mans '01 silverado 1500. The AC/cold air is only blowing out of the defroster. If i turn it to vent with temperature set to cold the air is HOT.. same with the feet the air is HOT when it should be cold.. the air is hot on every setting except the defrost setting. I know the blend door (not blend door actuator) is rotating as it should when turning manually by hand. I ordered a new blend door actuator in hopes that its my problem im just not sure if it is because I'm able to get cold air & AC to come out of the defroster. Any help is appreciated!
Silverado has 4 blend doors. 2 under dash, one p/s footwell, one d/s footwell. Problem is probably a different actuator.
What was your signs of problem ??
Is it the same placement and procedure for auto and manual temp control??
Would this be the problem for no air coming through the vents at all except defrost from the dash
Yes. When there is a problem with the actuator, it defaults to the Vent setting.
I have a 2005 Sierra with constant heat on the driver's side, but the passenger side seems okay. I found a recalibration procedure on CZcams that didn't fix the problem. I decided to remove the actuator to have a look. While it was out but still plugged in I turned the key on and visually witnessed it go from far left position all the way to the right and back to the left again. I pulled the actuator apart and set it in the middle. Then I plugged it back in and watched it travel counter clockwise when the temp. was set to cold. Again I unplugged and pulled it apart and rotated it to middle position. With temp. set to hot this time I turned the key on; and again it rotated counter clockwise, so it doesn't matter if the temp is set to cold or hot the actuator wants to return to the left position. Do you think this is my problem, or is the climate control module telling the actuator to be at hot setting?
Your going to have to check the control module, usually the blend doors have broken gears or you hear some clicking that eventually will stop. I have had to change out one or the other over the years with different vehicles. Something is telling it to go in one direction, from a shorted blend door actuator to the control panel.
I got mine going. There were no broken gears on mine either. It's my understanding the ones that broke consisted of metal and plastic. the plastic would shrink a bit, but the metal wouldn't allow it to happen without cracking. My actuator gear is all plastic and in good shape. I disconnected the battery overnight, and went through the recalibration process this morning and it's working great now. Thanks for the reply.
My wheelchairvan is A lot different dash then a pickup
Will it be the same for a 2001 Silverado 2500hd 6.0 liter eng ?
Should be the same
I hear knocking from my 2001 gmc... it's coming from the blower area.it sounds like a door trying to shut. My blend door turns great when I change the temp.what could it be?
James Ledesma go to the far passenger vent and pop it out. Stick a flashlight in there and look deep in there where the blower motor sits. Now watch and at the same time push the re-circulate and fresh air buttons. You may see a flap door moving and acting very weird and not staying all the way up. That was my problem right now. Hope that helps
Dang there is two of them... thanks for the help my brutha
@@jamesledesma 4 of them
what are the bolt sizes for this under area?
Should be 5.5mm or 7/32
I am trying to replace the actual blend door its self not the actuator... All you're doing is replacing the actuator not the blend door as it says on your video
You ever figure that out
@@dylanmonroe7075 Naw man I actually Just blew the engine a couple months ago. I'm fixing to drop anew engine in it... I'm thinking 12 valve. I've always wanted a 12 in a chevy. It already has a built allison 1000
I was going to replace the actuator on my son's 04 silverodo. When I pulled it off, the shaft is broken that that changes from heat to cold. What is that called so I can fix that?
Danielle Stanley
Mine was broken as well. I had to punchout the broken piece from the actuator and epoxied it back in place.
I have a 02 Silverado and my problem is the switch next to the heat, on the right. where u want air to go. (dash vents} floor vents} defrost ,etc . same vents stay on no matter where I set it to..sometimes it changes but I got to mess with switch back & forth.?? if u know what I mean.haha
Its the actuator by your gas pedal that controls that. I shot a video on that too just havnt uploaded it yet
This is not the blend door actuator, this is the mode door actuator, it diverts the air to floor or dash vents, it has nothing to do with temperature control. if you have the key on and the air system on and turn the shaft you will discover this. The blend door, which blends the hot air with cooler air to be able to adjust the temperature when heat is on. It is located closer to the hoses on the heater core. the blend door is actually located else where on this year model which requires removal of the entire dash.
Anthony Hagan is that the one that is pointing to that you're talking about that controls the vents because mine is stuck on the defrost vent
Anthony Hagan there’s 3 of does in your truck the one the guy is showing than one right above of the drivers feet and one on top one for the temperature and one that make the air flow hard and slow and the one the directs the air to your windshield feet or to the front 👍🏾
Antony is correct
Got cracking noise when switching vents. Could this be causing it?
Probably. Mine had been making that noise for probably a year, and yesterday it goes out completely. Stuck on blowing air to the upper vents and open exterior vents. Have not replaced it yet so maybe a connection failed but I'm going to replace it soon.
@@XSR95 thanks! Good info. In this video his temp door actuator went out, so what we had is probably similar but different location. Accessible without removing dash?
Bolt vs screws
SIMPLE IF YOU DON'T HAVE A CENTER CONSOLE
Youre talking about 2 different actuators
I GUARANTEE. you when you buy a new one it will be in the wrong position, and you'll have to turn your dash position switch a LOT before the new part gets in the right position. It's frustrating! The guy in the video got lucky.😖😎
LOL I with you buddy. I have to return and get another one with a center dot.
Size of the nut might be helpful I believe it’s 5.5 mm
good tip 💯 if you don't have a 5.5mm you can use a 7/32
That's not the blend door. Crappy title.
I want to see the blend door replaced not the actuator. You need to be more specific that you are not actually replacing the blend door. Wasted my time.
