2000 GMC Yukon XL 2500 with RPO Code C68 (Front Automatic Electronic Temperature Control) with RPO Code C36 (Auxiliary Heater) with RPO Code C69 (Auxiliary Air Conditioning) Auxiliary Temperature HVAC Blend Door Actuator TRQ HCA40137

THIS WAS EXACTLY WHAT I NEEDED TO GET MY CAR COOLING RIGHT, & AT A VERY GOOD PRICE, THANKS AEG

Arrived quickly, works as expected. It's not easy to install by design (GM Engineering)

Worked as described and arrived on time. I also appreciated U- tube video.

this was an easy install, needed short and long 9MM socket and a long 9/32 socket, the whole process took less than an hour for a guy who does not work on cars.

So far,so good!... Best price!! Slow shipping :-( Definitaly not oem parts but not my car so works 4 me :-)

The temperature control in my Suburban stopped working which was extremely uncomfortable because it was at max Heat! The actuator was not working and I found an "exact" replacement through 1A Auto. the replacement actuator was installed and my temperature stays exactly where it is set just like when it was new. Thanks 1A Auto!!

More than fair price. Shipped immediately. Return policy is great. Thank you.

Didn't work initially but after following the learn sequence it worked fine

Fits well and does what it should. Only concern is that the socket is made of plastic and the OEM being metal. Could wear out in the future but you can't beat the price for the quality of the part.

Ordered it then installed it followed the instructions to relearn the hvac system and driver side stays cold checked my fuses and no luck

Bought a blend door actuator for my 06 Yukon Denali. I was having hot air only on the drivers side intermittently and as time went on it was always hot on the drivers side. 1A Auto is great cause they have a lot of parts, fairly quick shipping, and a tutorial on YouTube for the removal/installation. Great company!!!

The part was for a great price and it works great Im buying all my part from 1A for all my vehicles. Thanks

Great price, part working great looking forward to ordering more from the company.

Had to call 1AAuto to make sure the part was correct for our 2004 suburban. After telling him we kept getting different suggestion on the actuator we need and one saying just ask a mechanic, the rep we spoke to at 1AAuto took his time asking questions about our vehicle and suggested this particular actuator. It was delivered on the day promised. We installed it and have had no problems with our AC blowing hot air since.

Bought this to fix a "no heat in rear" issue with my suburban. Swapped it and definitely works great now. 1A has failed to disappoint yet. They're adorable, fast shipping and best of all actually have quality parts.

Ive been ordering parts for my two Chevy vehicle for the last four years from A1auto and they have been very accurate with the parts that I needed the price are reasonable so I will keep ordering from A1auto for a long time to come. I recommend a few friends to use A1auto and theyre also happy with their service.

I replaced the original actuator. After reconnecting battery, it cycled between the limits as expected for calibration and never moved again. Stuck on cold. 1A Auto kindly replaced the part free of charge and same thing happened. I found this on Sparkys.com and wonder if it could be the issue. "Something else you need to know. If you buy a new actuator make sure the part numbers match. At the time of this writing the aftermarket (non dealer) application books are incorrect. You have to buy an actuator for the passenger side to get the correct actuator for the drivers side. Crazy but true. I cannot think of the number of actuators I have changed that have already been replaced by others. If you install the wrong actuator, it will rotate to a full stop and never move again." Please let me know if this is still a possible issue for that part.I put 3 stars because I don't know if it is the parts fault or mine .

This work but the cold one the controller is hot and vice versa.

this piece did not work, in fact, it worked completely backward from the factory's original part. Get AC Delco. Don't mess with this junk. They sent me two of them both of which did not work. Finally they refunded my money and told me to keep the items.

Perfect fit
