I think I know that smell, too. I've been told it's some kind of fungus growing in the AC evaporator or the air ducts behind it, where there's moisture. And there's several different species, with different smells.
One of them has a sweet smell which can be almost pleasant at first, but it soon becomes a a little nasty and nauseating.
Had a hint of it in my 86 last spring, so I started turning off the AC whenever it is colder outside than I want inside the car.
Ideally, the AC should turn itself completely off in such conditions, but it doesn't.
Anyway, the smell hasn't returned.
OP, I see you live in Texas so I guess this doesn't help much. Sorry.
