I've noticed lately this black fluffy stuff coming out in piece through the a/c vent. Not sure if anyone could tell me what that might be.






Thanks...

 

Might be parts of a filter after the blower fan. Not sure if your model is equipped with one.

 

There`s some black foam like gaskets around the edges of the plastic housing that contains the blower motor and ac/heater switching door etc..Not sure why it would be coming loose but that`s all I can think of in that area

 

Looks like the same stuff as a scotchbrite pad is made from. I think the later XJs have a filter made from that stuff. Maybe yours is deteriorating.
