Hello, what year and model of Buick do you have? this usually means there is poor or no vacuum to the ac system, the default is always defrost for safety so the windshield does not fog up, but depending on the year and model depends on if its vacuum actuated or electronically actuated, so let me know and i can get you fixed up.
