Joe....I know this doesn't address the question you posed, but every time
one of my cars did 
what you describe, it turned out to be due to a large volume of water pooled
somewhere in the
passenger compartment, on the floor or in the plugged air conditioner
collector tray.

Each pool had a different cause. But usually the water was in some footwell
and under a seat. 
The pools revealed themselves *first* by the window fogging, followed
*later* by wet carpet or 
moldy smell. 

Some causes were: leaks, faulty heater core, plugged air conditioner drain.

It is fairly easy to turn back some carpeting under a front seat and check
for water in the deep spot 
under the seat.  Or, you could put the car on a lift and remove some drain
plugs in the footwells 
if the car is blessed with them.
