It's not a design flaw. Honda engineers have no control over the elements.
The problem is related to conflicting temperatures(interior vs. exterior)
and humidity. My son was just complaining about this exact same issue
yesterday after having driven his 1990 Nissan 300ZX in extremely humid
conditions. I've experienced this same problem with most all of my cars at
one time or another. I've just always relied on the windshield wipers--and
it will eventually clear up and stay clear during your drive. It doesn't
usually plague you for very long after you've ran the wipers for a while.

Is this a design flaw by Honda?  I see it as a safety issue...and if it
is a flaw they should issue a recall, shouldn't they?

    All the Hondas I have owned do this. The outer side of the windshield
gets cold enough to drop below the dew point of the ambient air, and
water condenses at the lower edge outside. Lack of heat coming off the
engine to the same area also allows snow and ice to build up there in
the winter.  My old Pinto never had either problem.       bob

Can someone please post the best method of defogging ones' winshield in
humid (hot) weather?  I put my defogger on highest possible fan...and
the fog from the inside of the window goes away completely.  However,
the winshield is still fogged up from the outside and refuses to go
away without the use of my wipers.  Even then it does not go away
completeley (still a thin layer of fog)...and then returns fully in a
few seconds unless I keep my wipers on (even though its not raining).
I never had this problem before with my other cars.  It only seems to
be happening on my new 2005 Honda Acoord.  I spoke to a friend who also
purchased the same car...and he complaind of the same problem.
Neither blowing cold or hot air with or w/o the A/C seemed to get rid
of the outside fog.  Any suggestions?  Anybody else with the same
problem?
