GM Genuine Parts 15-72971 (89018365) Temperature Mode Valve Actuator Assembly

While my husband is a mechanic, I looked at a few youtube videos on replacing this part and decided that I could actually tackle it myself. I wrote down instructions from the video, and was able to replace the part myself. The only dtricky part that I could see in replacing it was making sure that you adjust your air temp while using a little dental type mirror to watch the little dial line up at 12:00 before detaching the old one and putting the new one in. Of course you have to unplug your battery and also there are other steps in turning the key to the "on" position etc to reset the computer etc. Just write the steps down and follow. But it was easy. The part is working great and I saved a ton of money! I think I purchased it for $83+ and the parts house wanted about $275. This part said OEM. My a/c is working great!

OEM part Fixed AC issue on 2013 Chevy Silverado. Driver side vents would blow hot air while p.side blew cold air. Located at bottom center of dash after removing cover. Has 2 screws securing module and 1 connector. New OEM part is the one w/o the sticker. Connect plug to AC module w/ key on to set module to park setting for easier installation. Driver side vents now blow cold air also.

2004 suburban had an issue. When AC on it blew heated air out of the driver's vents. This part fixed the issue, and it looked and fit just like the one I took out.

I bought this one through Amazon Warehouse Deals due to the cost of buying new so I haven’t run the AC long enough to see if it’s working properly. This was purchased to fix an issue with our 2007 Tahoe blowing warm air on the driver side while blowing cold air on passenger side.UPDATE: Still working properly after about two weeks. Both driver and passenger blowing cold air.

This is one of a few parts that I have ordered from amazon.com at a discounted price. GM parts stores or a dealer service departments seem to command premium prices on these little gadgets. You will not find a lower price than amazon. I installed one on my 98 Corvette (passnger side - though it is my understanding that the same part number applies to the driver's side as well). Works great. This actuator has the "new style" case - i.e: the black plastic case is glued together and not screwed together like the old style. Note: This does not affect the operation or installation of the unit.

We had a problem with the zoned air conditioning on a 2005 Tahoe not working correctly. The air conditioning vent next to the driver's window would start blowing hot air when it should not and the only way of normally fixing it was to stop the SUV, turn the motor off and restart. That would work most of the time. Youtube videos indicated a good chance that this was the solution and it was. The GM product is more expensive than generic aftermarket parts but this thing is a pain to put in so I paid more in the hope that it will work and not have to be replaced.

My 2004 Tahoe was not giving my hot air when I wanted it, or cold air when I wanted it. After researching online at sparkys-answers dot com, I found the problems was the blend actuator. Once I got this replaced, I regained control of the heater and A/C! This item is apparently an improvement on the OEM actuator, with updated software. My mechanic wanted to charge me $300 just for the part! I did have to buy a GearWrench 891427 27 Piece 1/4-Inch Drive (13mm) Pass Thru Ratchet set to get to the bolts holding it in, but I still saved a ton of dough doing it myself.

My 2004 GMC Yukon would blow hot air on drivers side (with a/c on) when all other vents were cold. If you shut off vehicle and removed the key, open door to cut delay circuit, then start vehicle it would cycle back to cold for unknown amount of time. Maybe rest of day maybe a few minutes.I checked blog websites and Sparkey's answers for info on this. 98% of research has been done on this problem aiming at a replacement to solve the issue. Follow their instructions.Relatively easy to replace. Tough part is getting the hush cover off and on as one screw is hard to access with normal tools. Need 7 mm to remove hush cover and 5.5mm for the actuator.Beside the cover, the actuator came right off and went right on. Look at the research and study the procedures and should be no problem. The hush cover install was again tough as the last screw under the console is hard to access. Now working like a charm.Oh Yes...Amazon has once again smoked the competition with their price on this item.
