Bob,

The problem with your solution is you can't make the wipers go faster in
heavy rain.
They will never go faster than they did originally and THAT was the problem
as I
perceived it.  The wipers on my 68 Midget are too slow in heavy rain.  If I
had
a motor that would go much faster I could easily build a switch and resistor

set-up that would allow slower speeds.  There are even under the dash
components
available out there that would allow intermittent settings but you are never
going
to get faster speeds out of the original motor.

Cheers!!
Jim

Then there was the mind reader who moved to Washington, D.C. and couldn't
find work.
