1996 dodge grand caravan wiper relay under hood for front wiper has no power why there is power to wiper switch and fuse is good?

I don't have a specific answer, however, I owned one of these vans and found the

wipers used to turn on by themselves. I have since sold it.

Ultimate control of the circuit for the front wipers is thru the Body Control Module located behind storage tray mounted below radio,floor level by right foot. BCM has two plugs one blue one brown. Circuit position exits switch to BCM then to relays then to motor.
