A few years ago the HVAC acted up in our 2012 Acadia and started blowing cold air on my wife's feet. Given that we were only halfway to Florida on the coldest day of the year, she was not happy. When we got to FL I took it into a local dealer and they replaced one of the HVAC actuators. The bill came to over $500. The actuator was about $110 and the labor was around $400. According to the service manager, it was necessary to remove the top of the dashboard to get access to the actuator.
There are four identical actuators in the car: Mode, recirculation, driver temperature and passenger temperature. A few weeks ago the recirc actuator started making noise, and I realized the mode and driver temp actuators were acting up, too. I decided to replace all four, which would have ran around a thousand bucks at the dealer. I decided to do it myself. There are a few not-particularly-informative YouTube videos on this repair, so I was pretty sure I could figure it out, too.
The OEM ACDelco actuators are fifty bucks apiece on Rock Auto, less than half what the dealer charges. There are also aftermarket units for half that, but I figured if I was going to do it I wasn't going to try to save a hundred bucks on parts, so I went with the OEM actuators.
I replaced the four actuators over three days. I probably spent about five or six hours total, most of which was just figuring out how to get the screws out with limited access. I only removed the trim under the dash, the passenger side console trim and the glove box. All of which were easy. The HVAC has to be reset with the new actuators, which you do by pulling the HVAC fuse, replacing it and starting up the car. Simple. Total out-of-pocket expense was $200 for the actuators plus five bucks for a set of Harbor Freight 'palm ratchets'.
