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?

Yes, but it only happened to me once. I turned on my wipers to get rid of
it. Not sure how to prevent this from happening, except to possibly turning
the a/c a little warmer? It only happened once on my '05 Accord so I never
tested this method. Since it is happening on the outside I can only assume
it is the colder air from the a/c that is chilling the windshield, creating
this effect. Could this be the reason? I'm not sure but can't imagine what
else it could be.

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

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?

Why is it a safety issue?

If moisture is on your windshield, use the wipers to wipe it off.

Or do you expect life to be perfect in all ways?

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.

I have to agree..Just bought a CRV with 300 miles on it. Night time 68f 90%
humidity, no problem with clearing inside but outside had to use wipers and
it still left a film which built up right away with moisture. Cleaned window
on outside and inside with good glass cleaner to no help. Tried heat and
cold and all in between. The wipers need to run almost constantly, hell I
thought there was a leak in engine compartment...
Never had this problem with other vehicles on same night- Jeep Cherokee and
Taurus.....
Sounds like a safety issue to me....Something is not right.....

Thanks

Its not a safety issue at all. when you use your AC on cool to clear
the glass, you're clearing the inside, by removing the internal
humidity. however, the glass is cold enough to drop below the external
dew point. Solution - heat the windscreen up - that is what the
defrost setting on your car heater is for!. Warm the glass, its not a
proble. My experiance is that american vehicles (such as the taurus
and jeep0 tend to have thinner and/or less insulating glass, so the
gradient between in and out isn't so bad.

I have, however, had this problem on EVERY SINGLE CAR i've ever owned,
one time or another - and most of them don't and never have had, AC.
in those cases, you run the engine fora bit, get the inside warm, then
stick the wipers on intimittant, or use the manual single-sweep when
needed..

What is all this obsessing with 'this sounds like a safety issue' -
even *IF* it was, there would be no recall, since a solution (THE
WIPERS) are already included into the design of the car.

I agree with your comments on heat.
My point is I tried with the heat with and without recirc. and the problem
was still there...
I never noticed this before with other vehicles....

The issue with the "safety" is that it seems others, not just myself,
experience much worse windshield fog on Honda vehicles than other
models/makes. I drove a Camry, Maxima, and Caravan Minivans...and
don't recall a prob with the windshield fogging in any of them. While
I don't disagree with your assursion that it is cause by outside
elements, it still seems odd that Honda vehicles seem to be reacting
worse than others. The wipers don't help too much especially when
driving on 2-way roads, at night. The oncoming headlight glare
illuminates the fog and makes it hard to see even with the wipers on.
Hence, the saftey issue. It is possible that the Honda glass is
thicker (it does seem to be very thick..never compared though) and
therefore the problem is somehow exaserbated. I tried warming up the
windshield (set my inside temp to 77-78) but it actually worstened the
problem.
