Never had any luck actually finding much in the Archives so I'm asking direct..

  Weird, but my wipers seem to have lost their high speed.  I think.  The high speed they did have
was never very much faster than the other speed, but now I really don't see any difference when I go
up to the second position with the wiper control stalk on my steering column...1984 Van with
intermittent wipers at the down position..off above that, then low speed then high speed with the
control switched all the way up, or counterclockwise, if you think of the steering wheel as  the
clock face...
  Is there a common problem with the wipers...like some contacts that corrode or a bushing that
wears out?  Anybody have any hints as to what to look at?  I'd rather not just "throw parts at it"
with  a whole new switch if I don't need one.
  You wouldn't think the desert southwest is a place where a Northwesterner would end up finding out
about a window wiper problem...but it has been raining here...last week we got over 2 inches in one
storm...equal to the whole amount of precip for the past 3 years!...so it does rain here, sometimes.
  Thanks,
