When in recirc the evaporator dries and cools dry and cool air if no one is in the cabin. If you experience fogging with the AC running there is a problem somewhere.

The rear window defroster turns itself off after a set interval, I think 15 minutes.

You understate the wrongness. Theoretically, i.e. assuming perfect sealing, recirc is not dealing with a constant influx of humid air; it’s making the same air drier and drier until the system can’t be made any drier. Now, if the cabin contains 5 panting adults in wet clothes and saturated carpets, I suppose that could contribute more moisture than outside air…

And recirc effects are different in a cold, high humidity winter (heater) than in a hot dry (AC) sunner.

When in doubt, read to the manual. Even if you don’t get a clear answer, you might learn new ways to waffle.

From the 2006 OM:

That sure helped the drive from Florida back in 2014, when Oldblue decided to split the flex pipe! I fixed it when I got home! A new catalytic converter was at the door. 5 fasteners and the 2 O2 sensors, fresh new task and done!
