Outside Air Leaking Inside Passenger Side Of Cab.

[96ahs]

I have a 2000 2500 that has a leak somewhere in the firewall, its not a problem except in the winter when the cold air comes inside and freezes my passenger's legs so I know its has to big a good size leak but I cant see a hole anywhere, any suggestions?

If you look back with the search option, there is a way you can stop it. If I remember it was pretty involved though.
