2Pcs HVAC Blend Door Actuator Replacement for Chevy Silverado 1500 2500 Suburban Tahoe GMC Sierra Yukon XL Cadillac Escalade Hummer H2, Heater Air Vent Actuator, 89018365, 604-106, 52402588

So Far So Good! Put these in the next day after they came; and they fit perfectly & work like a charm. Just to warn off anyone who is not experienced with doing this kind of job on your own, I will rate the difficulty on a scale of 1 to 10. Difficulty of the driver's side blend door actuator located in the center of the dash on the bottom of the HVAC box just above the tyranny hump is a 5 or 6 out of 10. Not too bad. It's totally by feel and you need a 5.5mm socket, short extension, and rachet. The Passenger side which is buried in the center of the dash mounted on the top of the HVAC box directly above the driver's side actuator is a 12 out of 10. No joke!! It's practically impossible to get to without taking the entire dashboard out of the vehicle as if you were going to change the HVAC box itself. I did get to it by removing the passenger side vents (2) and the passenger side airbag. As well as the pocket below the driver's side center vent. But I cannot recommend this to anyone. It was rough!! So take that under advisement. As for the parts, I can highly recommend these actuators for the blend doors. They arrived on time and a great value for the price. They are correct and work well. If this changes I will update this review.

Units fit perfectly and resolved my AC cooling issues

Works great

These are very good quality I use them in my 2004 Chevy Tahoe I bought six of them and replaced blend door actuator motors air mixture actuators everything they all work great. The only thing I could say you need to make sure you recalibrate your heating AC system in your vehicle that's not a negative thing it's just something you need to do.

Awesome Works as it should

These replacement units are Not as robust as the factory originals. Only one had failed after 375K miles, so I chose to let the Factory unit remain....

I should have done this years ago perfect replacement for 2013 gmc yukon rear ac. If your rear ac is blowing hot air but you have cold ac upfront this is the part you need. Youtube has videos to replace takes 30 min.

Did not work out of the box. Went to the salvage yard bought a used one for 10 bucks. Proble solved.
