:'(  - 2001 2.5 auto GV, 144,000 miles.  new plugs, fuel filter, and PCV valve other day.  Next day (which of course was loaded with squalls and road spray in a 300 mile jaunt to return daughter to college at NCAA baseball champs and do business in Portland), the intermittent wipers no work.  They act just like full slow speed.  They also stop whereever they are when the switch is off.  DId I do something to yank a wire or nudge a relay?  PCV took some maneuvering with wiring and hoses. 

Or is it just happenstance?

Ideas?  Thanks,

Pat
