Does anyone know if there is some sort of replacable filter for our HVAC system? When I lived in CA, I had to park under a tree all the time. At night the wind would blow and all these tiny leaves would fall into my cowl....then when I started up my car in the morning the leaves would blow out my vents into my face. Kinda funny, but annoying. I know lots of new cars have a pollen filter that you replace every so often. Do our cars have some kinda filter like that somewhere?
