Brown smoke coming from center vents.

["Raylynn A. Knight" <rknight@randomc.com>]

On my '88 80Q w/ 133K miles I just started experiencing a strange
problem.  I am getting brown smoke coming from the center vents.  This
discharge lasts for a minute or two after making a left turn.  I cannot
distinguish any particular smell from the smoke.  The air conditioning
appears to function properly otherwise and the smoke comes even when the
air conditioning is not engaged.  I have a 25 minute commute every
morning and evening and this has been occuring for a little over a week
with no other problems.  Any ideas on what this might be?

TIA
