With the advent of rainy season up here in Seattle I've sadly discovered my
Westy has a leak. It announces it's presence by dripping on my left foot.
Only happens in a fairly hard rain and while driving. Van can sit overnight
in a hard rain and no leak. I've only done a cursory check so far and it
seems to be dripping from behind and above the fuse panel. The windshield
seal visually looks fine.

I'm not really sure how to go about troubleshooting and the archives seem
strangely devoid of information on this. Any ideas on where I should start
looking?

Thanks,
-Roger
