Hello All,

Thanks to all who replied to my original post. It was not the
thermoswitch as I thought--it was the big green resistor behind the
driver's headlight. It took me 4 minutes in a parking lot to change this
$30.30 part, and all was instantly well. The fan came on like clockwork
as I used the A/C.

This part looks funny-- a hollow cylinder (chalky--ceramic?) with the
resistor wire wrapped around it and a green coating. It looks like
something out of the Fifties, but I'm told that many VWs have it, not
just the Vanagon.

Special thanks go to Andreas Fenner, Tim Smith, Ken Lewis, Max Wellhouse,
Jimmy Sanby, Don Gibbons, and Karl Mulloo, all of whom gave great advice
(hope I didn't miss anyone). You saved me a lot of time and $$!

Happily Rolling on with my Westy,
--Dave
