I had the same thing 2 years ago ... It was a rainy day, so i used the 
wipers very often. After 1 or 2 hours, they went out ! I stopped (it was 
lunch time..). The afternoon, less rain but  i had to use the wipers 
again. They worked !! No problem until the evening (but no rain ..)
Next day, rain ! The wipers worked but after while stopped again  (with 
some "click click" under the dash: circuit breaker ?) ! I try to jiggle 
the wiper switch button but i got an electrical shock (my other hand was 
on , i can't remember, but it was metallic )... so i used a rag. After a 
while they worked again and if i try to turn the button, no shock. 1 
hours later they went out and never worked again.  But i got other 
elctrical shocks if i touched the button and another metallic thing
As the rain was harder and harder i bought a special product (Rain X) 
and came home (400 miles !!)
Some days later i found what happened: please note that all linkage was 
ok, motor also etc..
On my car ther's a special feature: automatic action of the wiper when 
you push the windshield washer pedal. So the wiring of the wiper motor 
goes through a switch in this pedal. And the ground of the wiper motor 
goes through this switch ! Ther's a spring in the pedal which closed the 
switch (and grounded the motor) when you don't push it. Spring was 
weaked so the wiper motor wasn't grounded. The switch axle (and button) 
was perhaps insulated but contacted one of the motor wire inside. So the 
motor "grounded" through me....

Her's my 2002 "report" about this curious thing:

>As i said my wipers failed last weekend. I thought first that the
>problem was in the automatic parking switch of the motor.
>I remember that sometimes when i tried to switch off the wipers
>(when they worked) i felt a little electric shock when i touched
>the switch button, depending where was my other hand. Seems that
>there was somewhere a poor ground.
>The wiring of wipers has three grounds: one bolt of the wiper
>motor assy, the switch assy and the automatic windshield washer
>switch on the washer push pedal (this is a factory device on Imp
>and Chrysler, option for other Mopar: when you push the
>windshield washer pedal you operate also a switch which actuates
>one cycle of the wipers).
>Before removing the wipers motor / arms (need to remove glove
