A/C Issue
 

My new 2020 Expedition has a strange thing that randomly happens with the A/C on. The A/C will all of a sudden start blowing air out of the vents really fast and I have no control over it accept to just turn the power off. Also, there is a slight change in the smell of the air...like it went from recirculated air to fresh air. The air is still cool but not as cool as it was. This will last for a minute or less than it goes back to working properly. It's happened about 3-4 times now. I am going to take it in to the dealership and have it checked out. I just got my license plates put on and asked my salesman and he didn't know what it could be. Has anyone else had this issue or know what could be causing it? TIA
