[Vwdiesel] Flashing alternator light and windshield washer

[LBaird119 at aol.com]

  Odd stuff like that is usually from one of two things.  Normal glitches
in wiring, switches, etc., or a normal bad connection causing a ground
circuit feedback.  Those do some really weird, unrelated things!  Sounds
like you have a dirt or sticky switch for the washer.  A flashing alt. light
is
strange.  Solid glows of varying degrees are pretty easy to diagnose but
for a flash I guess I'd look for a loose wire or check the brushes like
Nate suggested.
