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.
We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the internet.

Blend motor worked as it should. It makes the HVAC work as designed.
Product works amazing thank you
Seems to work well.
works perfectly
Works good as expected
Heat and air are back and working! I like dealing with 1AAuto - their customer service is great, and I really appreciate their warranty. I've not had to use warranty service yet, but given their customer service to date, I don't expect any problems. The actuator seemed solidly built, and given my big hands and tight spaces, wasn't too much fun to get in and out, but their associated video was great.
Worked great. Perfect replacement for the drivers side of my 2013 chevy Tahoe.
Fit perfect, works great.
The part was spot on, the installation was cumbersome and required an a/c person to install them. Listen, not every part I buy, I can install and I'm okay with that aspect of my ability. I ALWAYS buy from 1Aauto because the quality and price and fitment are spec correct. So why would anyone buy anywhere else?
Part was fine; it was replaced and worked. I now have equal climate control. I have purchased parts from 1A Auto before with no issues whatsoever. Price is fair and delivery is good.
This will fit the right main actuator and the main inlet actuator.
Temp controller?
This will be the upper temperature door actuator.
There could be multiple reasons why you're having this particular problem. We suggest taking your vehicle to a nearby reputable shop to identify the cause. Once you know the cause, we'll be happy to see if we carry the parts and how-to videos needed for your repair.

No, driver and passenger are the exact same. I believe the rear actuator is the same also.
This will only fluctuate the temperature changing. If your air is not blowing at all then its something else. If it blows heater hot air and not AC cool air then this product will fix you right up. When temp blend door actuator fails it defaults to heater for safety reasons and that is why youre getting hot air. Replace with this temp blend door actuator and youre back to blowing snowballs.
This is for the front. Please enter your vehicle's year make and model in the search bar at the top of the page. This will display parts guaranteed to fit your vehicle. Just be sure to verify all of the information shown in the Vehicle Fit tab before ordering.

Hello Dan! This will not replace every HVAC actuator in your 2008 Silverado. This will replace the temperature blend actuator for most 1500 models, and the air inlet actuator for regular cabs with A/C only. Please refer to the fit list to see which actuator this replaces for yours!
