Small foam pieces are coming out of vents almost all the time when the air conditioning is on. Question is why and what is causing it?
Also If I have the air conditioning on heat I've noticed that the small vent on the drivers side next to the window doesn't blow out warm or hot air while the others do.
My car is a 2000 v6 4motion
Your airbox behind the dash has started breaking off and your hot and cold side vent no longer works well enough.
Remove the box, and refoam flaps.
