98 astro wiper problem

[rob cole]

I just bought this astro for my wife to drive to the city . got home and descovered that
the wipers don't work at all. after checking fuses(all fine) and I pulled the plug to the wiper motor and tested for some kind of voltage there and nothing . I need a clue as to where to look next so I don't end up just throwing parts at this van I have read all posts about wipers and have not found anything helpfull so far . thanks any help would be great!
