Our 2008 Acura MDX started blowing black stuff through a/c system (driver and passenger sides). When I picked up a piece of it and crushed it in my hand, it would disintegrate into almost a powder-like substance.
We took it to the Acura Dealer and according to them interior filter and a/c vent look fine and they would have to take the whole dashboard apart to see if there is a problem. Has anyone ever heard of this or does anyone have an idea of what it could be? It’s not affecting the performance of the car and the AC seems to function just fine. This black net-like particles started last summer.
Thanks in advance. Wan
