Hello,
  I have an issue where if I do not start and drive the van at least
every couple of days the battery goes dead.  I have replaced the
battery a couple of times and it does not appear to be my problem.
The only odd thing I notice is when I start the car or shut it off the
wipers tend to make one swipe, I checked to ensure the wipers are not
on.  They are not.  Also when replacing the battery the wipers made
one swipe upon initial connection.  Is there a common problem with
this or am I going down the wrong path?
