'87 4kq: A/C: good as it gets?

[Andrew Buc]

OK, I gather that I should have been looking to the side vents. All I can say
is that the owner's handbook gave me the impression that cooled air came through
the center vents. No occasion yet to drive around at length w/AC on, but I've
confirmed that the air from the side vents is subjectively quite a bit cooler.
However, I did get the following off-list:

> The A/C in my '85 4kq gets cold enough that I have to aim the
> center vents away from my hands.

This doesn't seem to square with the comments I've gotten that the center vents
provide uncooled outside air. TIA
