My air in the front of the tahoe onlys comes out of the defrost vents no matter what mode I select. Any ideas as to what it can be and what I need to replace top fix it?

Thanks

Thank you for the info!

Would it possibly be a blend door actuator? If so where is that one located? From what I have found out there are at least two installed up front.
