Is your washer bottle under the front of car, drivers side, like on S4 spiders?

so you have voltage at the washer motor...correct?
but the motor won't run?

just how are you measuring that? IGN on and someone pulling the wiper column arm back whilst you measure voltage at the black/white wire connector on the little pump?
OR, are you measuring voltage at steering column stalk?

yet when you power the pump direct it runs....correct?

a thread on getting inside the column stalk (sounds like your problem, depending):

and a schematic:
