When I went out this AM, the back window was misted on the outside. (40
degrees and damp.)  Put on rear defrost and this time it cleared up very
quickly, I mean I could see the filament lines appear which NEVER
happened last night.  It's like the rear defrost is too weak for inside
fogging, but can take care if minimal outside fogging with help from the
sun.  As far as the front fogging, put on AUTO and still got some
fogging.  Turned on defrost and it cleared up.  This is weird!
