I recently purchased a 2016 acadia the a/c worked perfect until the other day, when I started ìt up it felt like it was blowing hot and cold air at the same tim cold this be a setting ?.
Not sure, I know some vehicles will use colder air at the vent or head level to keep you alert and heat on the floor to maintain the designated temperature that was set. Check the owners manual or stop off at the dealership and ask.
