A musty odor may be noted from the heating, ventilation and AC (HVAC) system after sitting for two hours or more due to condensation in the heater case. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

bits of thin black foam are coming out of ac vents... It's as if a liner or filter has deteriorated and is flying out in bits and chunks ...musty smell too. Hoping its not too $$ to have fixed at Dealer.

I have a smell coming out of the vents. At first I thought it was the last mechanic that worked on it and have used a couple of bottles of Frebreeze. Nothing. I thought it was like that Jerry Seinfeld show then realized it was coming out of the vents. It can get pretty nasty. Glad I found this site!!!
