another common source of water inside cabin

[///M42 sport]

Check this tube attached to the passenger side of the firewall. Mine was clogged with debris. Just twist it off. Now I just have to figure out how to reattach it

yep, its called the elephant trunk/snout/nose, etc.

its fairly common for them to get clogged.

my friend bought an extremely clean lagunengrun 325is, with a full leather interior that had been redone 2 years prior and was pristine, had 135k miles, for $1300... cause water would get in the cabin and flood. the only thing it needed was the elephant snout to be yanked and cleaned.
