Sounds like a possible blend door problem. If you are not knowledgable in automotive AC's, this one is best left to a professional.
Even to diagnois this will require going behind the dash. All of the controls and ducting are nicely hidden behind the dash area.
A 2006 with ? miles. At this age it could use a AC system checkup also.
Thank you for taking the time to share your knowledge. I was thinking about the air conditioning check up too, but since I am not a technician I am not able to offer ideas such as that.
I hope you had a great weekend.
