For all those who responded to my question about headlight problems,
many thanks.  For those that pointed first to the light switch on the
dash, congratulations, that was it.  And a special thanks to Chris
Delong of Fine Tuning in Seattle.  Even though he wasn't really open
today, he was willing to let me try the switch out of his Vanagon to
assure that was the problem.  But even better, he found in his shop a
replacement switch.  Even though from an different model and missing
several pins that are on the switch for my '90, it works fine, all
lights work.  I have no idea what the other pins are for, I guess I'm
left to trying to decipher the Bently diagrams.  Chris was a life saver.
  I have an important birthday party to go to tomorrow night and would
have had to miss it (the other car is in the shop).  BTW, local VW had
no stock and wanted $81 to order a switch.  Bow Wow did not have.  And
my local source, Rudi at Schaffner Motors was closed today.  Thank again
Chris.
