Had the same problem through the summer under slightly different
circumstances with my hi-mileage '92 100CSQW.  Thanks to a tip from a
q-lister, the problem turned out to be a clogged "secret" drain under
the plenum beneath the dash instrument cluster under the hood.  You with
me?  The drain had four years' accumulation of leaves and twigs that
caused the fogging, and eventually water in the footwells after heavy
rains.  Good luck, Shaun
