Chevrolet HVAC Blend Door Actuator Purchase

Excellent quality and helpful youtube videos to install. AC is running cold again, cheers.

April 24, 2026
Works perfectly.

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.

Driving in cool air again

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.

Perfect fit

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 got an '05 Tahoe Z71 pack. This should fit, right? I NEED to replace mine. It's already 20 out frosted windows, and my defrost works, but heat has been a no go.

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!

Is this the actuator that would need to be replaced if the entire front AC is blowing hot? Our back AC in the Yukon still blows cold. We took the actuator out and get moderately cool air when we slide over the little door where the actuator was.

YES!!! This solved my problem in my '05 Yukon XL w electronic climate control!!! Good Luck!!!!

What do I do if the rod that goes in the blend door breaks during removal of the old one?

Try and locate one either through the dealer or salvage yard I suppose.
