Both my current Caprices and my former Daihatsu had it this way;
hot, dry air available for both defogging and clothes/hair drying
at any outside temp. Lovely. 
...not having a working A/C system, I hadn't realized this old
5kS doesn't do it like that. Neither do later Audis?
Call me comfy-chair-dependent, but that actually
rules out any future newish-Audi purchases.
