It's likely coming in from the antenna, where it goes into the cockpit.  The
grommet there usually is rotten, and I use this material to seal it:

This is a permanently flexible moldable putty that you will find many uses
for on the Vanagon. I use it under the bolts entering the pop top as well.

Subject: Water entry ?

We (www.slowcarfasthouse.com) just passed through major rainstorm. As I was
driving I felt water on my left foot. Seems to be entering all the way
forward on the bulkhead in the left corner. Any suggestions for me to locate
and stop this?  May explain why carpet under floor mat has been damp lately.
