[T3] Wiring?!

[John L. Morgan IV]

Jim,

Thanks so much.  IT is always something with the 70fb which makes it verrrry
exciting.
The knocking still needs to be addressed, but I havent attacked it since my
initial questions.
I re-mounted the wheels and tires and still feel some play in the front,
which I assume
is the knocking I hear at hard stops, but since the car is a daily back and
forther (I am a teacher
and my commute is relatively short), I have tried to deal with it (not the
bet thing I know), but
my wife kills me when I throw $$ at the VW.

Thanks for the wiper advice.  I will look at the fuse # spots you mentioned
and see
if anything looks loose.  IT seems very hard to see anything close to that
wiper switch.
Im always getting things in my eyes, lying on my back with a flashlight,
trying to figure it out.

Oh the joy!
