Greetings,

I'm fighting to eliminate fumes that appear to be coming through to the cabin. Ran the air and the heat, placed my head near the vent and noticed the mild scent of fumes. Got a charcoal filter which I plan to install tomorrow (actually later today, lol) but was wondering if it's possible to determine the path of the air that comes into the cabin. Anybody know or able to perhaps point me to a reference?

Thx!
