A good advisor would have explained the situation to you. Trust me we don't want to have to give estimates like that. We know we aren't going to get the job but even if you explain it to people and give them the option when it does break again guess what? Either me or the dealership is eating that repair so we just can't do it anymore.

I think you have a broken blend air door, you may also have a broken recirc/fresh air door as well. They are both common. You could always have the a/c system sucked out and pull the dash and case yourself.
