Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the blend door actuator on this 2002 Chevy Suburban. You'll need a new blend door actuator from 1AAuto.com, a 7mm socket and ratchet, and a 7/32 socket.
Start off by removing the 7mm bolts from this panel underneath your glove box, this one being right there, and we'll fast-forward as Don removes these 3 bolts. Pull down the panel and remove it. Your blend door actuator is right here. Just push the tab on the harness, pull it free, and then remove that 7/32 bolt and the other one on the other side. We'll fast-forward as Don does this. Now pull the actuator down and it will pull free.
On the left is the old blend door actuator; on the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Take the blend door actuator, push it back up into place, and replace those two 7/32 bolts. We'll just fast-forward as Don replaces those and tightens them up. Connect the harness, push this panel back up into place, replace those three 7mm bolts, and you're all set.

In this video, we're going to be replacing the temperature door actuator on this '02 GMC Sierra. This is usually the problem when you turn your temperature control knob, and you don't get any warmer or cold air. You're either just getting warm or just cold or just one temperature. Tools you'll need are a 7mm socket and a 7/32s inch socket with an extension and a ratchet.
On the passenger side, there are four 7mm bolts to remove: one there and one in there. There's one up in that hole right there. I can't really film it. And then over here, closer to the gas pedal there is one right there. Once you remove those bolts, just reach in, kind of pull it down and out of the way.
The actuator is right down here. It's held in with two bolts, they're 7/32s. One of them is right over here. The other one's on the opposite side. It’s a little more difficult to get to. Kind of have to stuff the wrench in there. Kind of starts coming out, and you can disconnect your wrench and just use the socket. Okay.
So the actuator then comes down and out, and there's a little connector right here. Just push and disconnect. Very important when replacing one of these actuators. Make sure that you do not power the actuator up before it's installed.
So make sure your key is off, and you'll see that I actually install it before I plug it in. So install. Push it up and in, and get on the pin in there. I'm starting this bolt over here. Just use my socket. Okay and the final part is to put your cover back in place. You want to push it up in there.
You push it kind of against the firewall first. And I'm sorry about shaking around a little bit here, just trying to film with one hand and push it up in there with the other. Push the front of it up and in first and then make sure you have everything lined up. Okay.
As you could see here, these are the passenger side outlet holes. Make sure those are all lined up and then start your end bolt here, and then I'd recommend starting the ones over near the driver side. Once you have those lined up, then the other two middle ones go in pretty easily.

Excellent quality and helpful youtube videos to install. AC is running cold again, cheers.
It fit and works perfectly. I can now turn the heat all the way up and when it gets too hot I can turn it down and it actually doesn't stay on hot. Perfectly regulates the temp in the cab of my truck. And very easy to install.
All good, good tech help
The actuator worked fine, I had replaced it before, your matching part made the installation easy.
Worked exactly as expected. Saved me hundreds of dollars in car repairs. The instructional videos that accompany the 1A auto repair parts make the job so much easier. Thanks 1A auto.
Worked!
Why have hot air blown on the driver. Just buy it and thank me later.
It was a non working part out of the package. What's the return policy.
The part was exactly what I needed and worked perfectly and didn't take long to install. Good buy!!!
It was exactly what I needed. The part fit perfectly in my 2001 Chevy suburban. The part came quickly, and their instructions online on how to install were perfect as well. Made a quick job quicker.
I've got an '05 Denali XL There ar three of these actuators under the dash. I took a shot at changing the easy (lowest) one, and it solved the problem.... not too dificult to get to either. However, gotta say, if it woudl have been one of the other two... where you gotta take the dash apart to get to them..... I'd have bailed on the project. FYI.. if you DO change one or more off the damper motors, you must reprogram them all to work together. There is a procedure to re-time them all together on line. Cannot find it right off hand tho. good Luck!
We do not have the AC Delco replacement number. If you'd like to contact us via phone or email we will be happy to verify if this part fits your vehicle, and if it does not we can help find the correct part. Thank you.
YES!!! This solved my problem in my '05 Yukon XL w electronic climate control!!! Good Luck!!!!
I change out the actuator and it work.
Try and locate one either through the dealer or salvage yard I suppose.
