Check for voltage at the washer motor wire when a helper presses the switch. Since the '96 models, this is all controlled by the insanely complicated Body Computer. If you find voltage to the connector for the washer motor, and the ground wire tests ok, replace the washer motor. If there is no voltage getting to the connector, suspect the Body Computer as the most likely cause but it wouldn't hurt to test the washer switch first.
The washer motor is under the fluid reservoir. I never had to work on one so I don't know what it takes to get to the plug. You might have to reach it from under the van.
