Foam coming out of windshield vents

[Hugh]

Anyone ever experience this before? 99.9% of the time I have my climate control set for Full Auto. I just completed a round trip drive to NY and early one morning it was foggy so I manually selected the windshield vents to defog it and set the fan on high. After a few minutes I got showered by a bunch of small pieces of rotted brown foam. The type that you would see to seal a/c ducting.
Any ideas if I should bother pursuing this further? It didn't happen again while leaving the windshield vents blowing on high for over an hour.

I had an '85 Ferrari a couple of years ago which did the same thing a couple of times. It was just dried-up pieces of insulation foam in the ducting systems , as you suspected. In my case, it stopped after doing this a few times. I would gues that , as these cars get older and older, stuff like this foam will eventually gradually deteriorate over time. With the Ferrari, there was also foam rubber surrounding the radiator which was so deteriorated that it would literally crumble when touched.

Same thing happenned to me going for a car wash (luckily when i was in line). So they had to do some meticulous vaccuming. Then it dawned on me my car's gettin old. Nevertheless turn blower on insert 1/4 to 1/2 bottle windex (outside through cowl)cleans it and gets rid of any odors.:wink:
