There are two relay's in the under hood fuse / relay box . Wiper relay an wiper relay 2 . Maybe one is bad . also check fuse #14 25 amp. Wiper fuse.Plus the BCM - body control module has a hand in making the wipers work . Are you familiar with automotive electronic control modules ?
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper micro relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIP/WASH 10A fuse
• WIPER 25A fuse
Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper micro relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay switched output to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.
Check the Fluid First, check that the windshield washer bottle has fluid and that ... If the pump is not heard, check the fuse panel to see if there is a blown fuse.

Here is a step by step guide to diagnose any trouble with yourwindshield washer pump, or other issues that ...
A washer pump in a car's windshield wiping system moves washer fluid from a reservoir through hoses. The motorized pump pressurizes the fluid to allow it to be squirted from the hoses through nozzles onto the front and/or rear windshield of a car. The washer fluid helps windshield wipers get rid of rain, dirt, or other objects that can interfere with a driver's visibility. If your washer fluid is not being sent out when activated, the solution could simply be filling the washer system's reservoir with more fluid or cleaning the nozzles and hoses. In more severe cases, the washer pump may need to be replaced. Here are steps to troubleshoot a windshield-washer pump.
usaully located at the bottom of washer tank where you fill the window washer fluid some have fuses in the fuse box others the wires corrode or break at the pump or pump burnt
Check fuse in fuse box inside vehicle,if good,then go to windshield washer pump and disconnect wiring,get meter and check if power is going to pump,if so then pump is at fault,if no power,thenwiring could be short somewhere to fuse box.Also check your washer hoses,that they are not kinked or came loose.Pump could just be loose.
More than likely it's the pump itself. I say this because in a nutshell your pump is computer controled. It receives power through the CAN system on your vehicle. If it were just a fuse MANY other things would not be working. I would see if you are geting power and ground to the pump. If you are then replace the pump. If you are not you may be looking at the switch or a wiring problem or in the system itself. Wish I could give you just a fuse but it's not that simple on your vehicle. I gave you a descrition of how it works but it can be a little confusing.
The windshield washer pump is part of the windshield wash reservior.
There is an electrical connector located on the bottom of the reservior.
That is the pump .
If the pump is not in the reservior. I would just trace the washer fluid lines from the sprayer on the vehicle back to the pump. The lines just might lead back to the reservior for the windshield wash solution. Then you will have confirmed the pump is in the reservior.
You may have to get a new reservior. The pump might not be seperate item, I am not 100% sure on that.
I also would double check the fuses and any relays related to the washer pump.
Finally, I would check the washer switch if you replace the pump and still is not working .
