Default AC vent blowing chunks

The right passenger side AC vent in my 99 Camry started blowing out
bits of black, very sticky foam-like material whenever the AC is on.
They go all over the car, in my eyes, etc. I also saw a piece of the
stuff about the size of a matchbook in behind the louvers of the vent.
Even before the chunks started, the vent would whistle whenever it was
closed with the AC running. I have the louvers pointed down & to the
right to keep the chunks out of my eyes, but it's getting the door and
seat all sticky. Any ideas what this is & how I can fix it? Is there
a replacement part I need to get?

That's the foam insulation between the various duct components
degrading. Eventually all the loose pieces will blow out. I'd just
wait it out. You could disassemble the duct work and replace the foam,
but that's more work than I'd want to do on an 18 year old car.

Is this normal for a car 7 years old ?
I have never had this happened on my '95 camry.
I have about 207k miles on the odometer now...

Math never was one of my strong points <grin>.

Now I wonder why the foam is degrading after such a short time. Here in
the Florida heat that problem doesn't usually show up for about 10
years.

I'm in Oklahoma heat/humidity, and though it's probably not as bad as
Florida's that's the only cause I can think of for this. Only one vent
out of the four is affected. Will the lack of foam in that one cause
problems, or can I do without it?

I've never replaced any of mine (3 Toyotas over 15 years) and it doesn't
seem to affect anything.

My 97 does this just from the windshield defrost vents.
I turn it on low to avoid that, looks like a major pain to fix it.

Sometimes, if the vent controls have been left unadjusted for a long time,
the foam seals sorta stick and tear-off once the vents are changed position.

Wow, I thought I was the only one (not). I have had a 97 that did the
same thing, now I have a 2000 and it's doing it too. It is most
definitely a weather related issue. I have only one issue with it at
all. Mine losing the foam, started a high pitched whistle on the
drivers side (by the door) dash vent. The other side is not making the
whistling noise. I plan on pulling just the one vent off and replacing
the foam with something from Home Depot or something.
