As I posted 2 days ago, my van's windshield wipers
sometimes work and some times dont.  I tried fiddleing
with the column seitch (blew air in & tried sandpaper)
but it still wont work.

I ran an errand today and I left the switch in the
"intermitent" position to see if a bump in the road
would cause it turn on.  NO.

BUT!!!   When I turned on the headlights, the wiper
went ON.  It worked in all positions.  Turn head
lights OFF and no wiper motor!!.. Headlights ON, Wiper
motor ON.

Can anyone use this 2nd clue to suggest a solution to
the problem?     Thanks,   Malcolm (Not much of an electrician)
