I saved these from last year's posting to the list (with credit to the
noted listers) ....just be sure to check these first in case it's
applicable to your 90Q.

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

I would suggest that you check the spring on the air recirculating flop. If it
is broken, you are not getting fresh air from the outside and with the increase
humidity inside you are having this problem.

Another possibility is your heater radiator core; this however is unlikely since
your car is not that old and you would be losing antifreeze.

Last but not least, check for the blocked drain if you park near a lot of trees.

Good Luck
