What would cause the washer pump to not work?

The washer pump, which operates both front and rear, has quit working along with the entire back glass (rear defrost, wiper, and washer fluid.) I have checked the fuses, both under hood and under the dash, and all checked out. I then took a test light to see if the washer pump that I replaced was getting any power and there was no power running to it. Cannot find which relay is for the washer pump. The only relay that I see in the owners manual that has anything to do with the wipers is front wiper relay, which are working fine Not sure what to check next.
