Washers not spraying

2017 silverado 1500 5.3

 

Wipers function normally but no washer spray. Tested all the fuses. Put 12v to the pump and the pump runs. No power to the pump tho. I heard there are relays but they are not serviceable. 

 

Any ideas?

Underhood fuse box.  Relay is integral to the printed circuit board in the fuse box.

Any way to test that is the issue before buying a new one?

Unplug the washer pump and check for power when you hit the wiper washer switch.  If its dead, you will have to remove the fuse box and check for power in connector X3, terminal K6 and check for 12 volts there when you command the sprayers.  That's the 12v power from the BCM to the relay.  If you have 12V to the relay, needs the fuse box.
