what? are you talking about?
the foam that comes out of your vents?
if you are.... look at a calender, then look at the year of your car, then back again, and again one more time. put 2 and 2 together and eventually youll get to the point where you realize that over time, constantly heating and cooling from the heat and AC and that fragile foam that creates a seal around the pieces of the vent system that are linked together.... deteriorates over time, and eventually comes out in pieces......
best way to get it all out is to close all but one vent, crank up the air, and work the vents back and forth... turning the air up and down constantly, eventually you will get it all out.
its old. no way there would have been a recall 18 years later.
