2011 w/ dual climate controls. Sometimes when the windshield fogs over, there is a section of the windshield (directly in the middle) that will not clear. The temp seems to change with the controls, eliminating a blend door issue. Is this normal for the GMT900s? I sat in my driveway waiting for it to clear for about 1/2 hr yesterday.
