1982 Scirocco Electrical Problem

Thank you everyone.  The problem is fixed.  Another one of those that, if one had only learned to think logically, you would have saved a lot of work!  I misled myself by thinking that the only place the two circuits were adjacent was in the switches or at the relay panel.  There was, of course one other place, where the w/s washer motor and the front RH signal lamp share a ground wire at the motor connector.  I really don't think VW meant these cars to last for 22 years.  They used a cheap plastic insulated wire with a stranded conductor of bare copper.  This reacts in our weather conditions to corrode the wire away just at the crimp of the connector, leaving the wire apparently still attached, though only by the insulation.  In my case the wire going to ground open circuited, leaving the wire from the lamp intact.  The perfect "ground loop"!  Ten minutes to fix then another forty to put back all the underdash panels that didn't need to be removed anyway.
Thank you once again
