It is winter time again and once again I am soaked.  Water appears to be
leaking into the front ventilation duct, and from there flowing down both
sides of the van, all the way to the door vents.  So, please if anyone has
any ideas about occluding this flow and allowing me to open the doors
without a splash of water.  I would appreciate it.

PS I tried using the search engine but it was too slow for my browser.
thanks
