WPR/WSW fuse 25amp is located in the under hood fuse box . This a complex system ,controlled by the BCM . If you find that the fuse is good i suggest you take it to a qualified repair shop . This wiper / washer system has the capability to set DTC'S - diagnostic trouble codes !
DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
The Body Control Module (BCM) monitors the control circuit of the WIPER relay. The voltage level should be low while the WIPER relay is de-energized and near system voltage when the relay is energized. After the BCM receives a low, intermittent, or mist signal from the wiper/washer switch, it responds by applying battery voltage through the WIPER relay control circuit to the coil side of the relay, energizing the WIPER relay.
DTC B3873 00: Front Washer Relay Circuit
DTC B3875 00: Wiper High Speed Relay Circuit
DTC B3922 00: Front Wiper Function Select Circuit
I really don't think this is a fuse problem , but if it is a blown fuse they don't just blow for no reason . Low resistance high current flow ,short to ground .
The wiper / washer switch is a input to the BCM - body control module . Depending on switch position the BCM will energize a relay the WPR relay or the WPR HI relay .

This is a complex wiper circuit ! The place to start would be to check for DTC'S - diagnostic trouble code's .
DTC B3715, B3716, B3717, B3718, or B3719
The body control module (BCM) controls and monitors the state of the ON/OFF wiper relay control circuit. When the windshield wiper switch is placed in to a low speed setting, a signal is applied to the BCM. The BCM then applies battery positive voltage to the coil side of the ON/OFF WPR relay through the relay control circuit. This energizes the relay, allowing battery positive voltage from the FRT/WPR fuse through the switched side of the ON/OFF WPR relay through the HI/LOW WPR relay and to the windshield wiper motor. Ground is applied at all times to the coil sides of the wiper relays and the windshield wiper motor from G105.
• DTC B3717, the BCM detects a low voltage level on the supply circuit of the wiper micro relay for 1 second when the relay is energized.
• DTC B3718, the BCM detects a high voltage level on the supply circuit of the wiper micro relay for 1 second when the relay is de-energized
Your best bet mite be to take your vehicle to a qualified repair shop !

WPR fuse 25amp under hood fuse box .
Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper PCB relay
• Wiper high PCB relay
• Windshield wiper motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR fuse 25 A
• WSW fuse 10 A
This is more then likely not a fuse issue !!!!!!!
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !

Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.

Both headlamps an wipers are controlled by the BCM - body control module ! There is a lot involved in turning on the headlamps an wipers , here is GM factory service repair manual description .
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through a resistor internal to the switch and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WPR relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WPR relay and out to the switch input side of the WPR HI relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the WPR relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
There could be DTC'S - diagnostic trouble codes stored in the BCM .
DTC B3715 DTC B3873 DTC B3875 DTC B3922
Your best option would be to have it checked out by a qualified repair shop . Hooking up a diagnostic scan tool to check inputs an outputs of the BCM is the best way to find the problem . Could be the switches (no input to BCM) The BCM could be at fault . There are relays involved in both the headlamps an wipers , couldn't be three relays bad at the same time .

Pull the two fuse's , RR WPR 15amp in the instrument panel fuse box an the RR WRP 25amp fuse in the under hood fuse box.

No wipers at all , hi , low , delayed ? You really need a factory scan tool to diagnose this problem , there is a lot involved ! The switch , BCM , wiper relay , an wiper hi relay ! With a scan tool you would be able to access data parameters in the BCM - body control module . When you turn the switch to turn on the wipers , that's an input to the BCM , the BCM then energizes the proper relay in the under hood relay box . Turning on the wipers ! Plus there could be trouble codes stored in the BCM pointing to a problem .
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through a resistor internal to the switch and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WPR relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WPR relay and out to the switch input side of the WPR HI relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the WPR relay can also be commanded ON/OFF by using a scan tool. Refer to Scan Tool Output

You need to remove the trim panel inside the back door, Unplug the motor, Be sure you have power on the Orange wire with key on, then test the Grey wire with wiper on, key on and if power? then likely bad motor If NO power on one or both wires at the plug? then fuse for rear wiper or bad switch the orange wire is from the RR WPR fuse in the under hood fuse box.
I doubt the other fuse is bad as if it was, the rear washer would not work So,, be sure power on orange wire, then check power on grey wire with wiper on and key on. No power on grey? bad switch. No power on both orange and grey? likely motor. This is the only way to test the system

The WPR fuse is for the wiper and washer system. It is a 25 Amp fuse that powers up the WIPER HI relay, WIPER relay, and the WSH relay.

Check the main fuse box next to the battery, # 8 max fuse powers IGN MAIN 2 Ignition Switch to Fuses (I/P): BCM PRGRM, FRT HVAC LOW/MED BLWR, FRT WPR/WSHR, HVAC/DRL, MALL/RADIO/DIC, PWR QRT VENT, RR HVAC, RR WPR/WSHR, SWC ACCY & PWR WDO Circuit Breaker.

#3 circuit breaker is the front window breaker, try swapping it out with another breaker beside it and thats located in the side dash panel also.

The common cause of failed power window function is the switch on the doors going bad from dirt. Does the power window on the passenger side go down with the passenger side switch?? if it does then its a bad drivers side and and try cleaning the switch with electrical contact cleaner. 95% of the time this will save you from buying a new switch.
