My '88 5000CSTQ had a similar fogging problem. Minutes after getting into
the car, all the windows would fog up. Setting the climate control to the
Defrost setting helped a little but with more people in the car it couldn't
keep up.

The Fix....
I read a thread on here several months ago about a similar problem, the fix
being the recirculation flap. I took out my glove compartment and the glove
compartment liner and few other plastic pieces to gain access to the recirc
flap. The recirc flap is actuated be a vacuum servo. When the servo retracts
a "return" spring is supposed to pull the recirc flap closed. In my case
that spring was broken. Went to my friendly Ace hardware and bought a
similar spring for 97 cents. Reinstalled and the fogging problem has not
returned since.

Hope this helps!
