This a "FAIRSUN" brand item inside a GM/Acdelco box. Did not notice until installing the part.

works great, just make sure you know how to calibrate the automobile when you install it or you can strip the gear inside again.

These worked great for my 2006 Envoy Xl rear comfort controls. I actually bought 2 of these. One was for the head/floor blend door and the other was for hot/cold blend door. I recommend replacing both at the same time as I had one break and then the other a few months later. I made the mistake of buying a different set on amazon for cheaper but when they showed up they were set 180 degrees off and would not rotate enough to work on the vehicle. These mounted up with no issue and after following the recalibration process they were ready to work in about 20 min time ( total time for install and calibration.) calibration process was turn off all climate controls. Turn vechile off. Pull HVAC B fuse ( under rear (2nd row) driver side seat in fuse panel) then replace both actuators and plug them in then replace fuse and turn key to on but do not start vechile. You should hear/ see actuators turn all the way to one side and sit then turn all the way to the other and sit. After a few minutes they are ready to use. Start car and check complete operation.Wish I would have just bought these from the get go. Definitely easy to replace.

Fixed my "Clicking" / vent problem. There's 2 of them back there and you'll only know if one is bad by taking it apart and looking for broken plastic gears inside. Metal gears would've lasted forever but would've cost GM 5 cents more! I changed both while I was there so hopefully I won't have to open up that part of the vehicle again for another 14 years.

I needed two of these for my 2005 Chevrolet Trailblazer EXT. After installation by our Chevrolet dealer it not only repaired my Rear A/C temp zone but just like the other reviewers stated, the clicking noise is gone as well. Works perfectly.

I have a 2005 Trailblazer that had the click-ity clicks in rear ac system on startup. I did have to replace my battery when this all started. I replaced both actuators since it was a bit of work getting back into the panel to fix this. There are a lot of guides and tips out there on how to install these so I will not get into that. BUT if you are changing the hot/cold actuator (the one on the side not the top) you WILL need a flat head screwdriver. The star stud that this installs onto has a slit it the tip because the shaft will have to be turned a little to get the star pattern to line up for the new part to slide on. This was a little tricky but as long as you don't use force and take your time you should have no issues. This is the one thing I didn't find in any of the guides or videos for this job.

The product installed relatively easily and it worked great for about 3 weeks. No thumping noises coming from the rear of the 2005 GMC Envoy. However, after about a month, the thumping noise is back again. Very frustrating.

I replaced this part 6 months ago, now the stupid thing is clicking AGAIN. I didn't disconnect the battery at all or change any fuses, so why it keeps breaking is beyong me. GM needs to pull their heads out of there butt and quit making stupid crappy parts for their cars that are so easily breakable. One easy fix would be to make the stupid thing with metal gears, the designer at GM must have been home sick that day. So I'm curious how many more times this cheap ass part will break during the rest of the time I own this car?

This product was shipped fast and worked perfect first time but I'm sure I will be buying another one do to the fact its not the actuator that's the problem but the design of the blend door stopping point its always under a load in the at rest position. So keep up with the good pricing and delivery and we will be friends for a long time
