Answer 1
This is the default for when there is a problem with your A/C system . It is a safety state so you will have a defrosted windshield and usually there is heat in the defrost air as well. here are some shops to help you diagnose your truck http://repairpal.com/directory?address=89011&car_brand_names=Chevrolet -
