2008 Buick Enclave Question: No air comes out of the defroster or floor vents



MDK, Hot Springs National Park, AR, January 20, 2011, 10:12

I have a 2008 Buick Enclave, 65,000 miles. Recently we have been unable to get any air to come out of the floor or defroster vents. Any ideas on the problem and/or fix?

    I have a 2009 Enclave with the same problem, 55k miles. The actuator for the diverter vane was bad. It had failed in the defrost position. The problem went away after the actuator was replaced.
