Hello new member thank you for the add. I have a 2017, and we have had an issue when the air is put on the face it blows moreso on the feet. So much so I gave it to my wife practically brand new. In the TX heat I need all the air on my face! Now recently when the air is on now the middle and back vents blow hot. If I lower the rear temp and push the auto button it will turn cold. When the kids are cold I raise the temp and the heat comes back. Any ideas? Some say a control module and others blend doors. Just wanted to get ideas and how hard it might be. Thank you in advance!
