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 !

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.

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 .
In the under hood fuse box , should have diagram inside the lid . Front wiper's or rear ? Front fuse # 36 - 25 amp. Plus Two relay's PCB hi and Wiper PCB relay . Wouldn't think this being fuse problem . Wiper switch , motor etc... The wiper's are control by a computer . BCM - body control module .
The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes: Mist, Intermittent, Low, and High. When the front wipers are in the intermittent mode, there are 5 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). The rear wipers has an only one mode.
If the fuse is bad , could have a short to ground or wiper motor pulling to much current (amps) . Fuse's don't just blow for no reason ! Could also have DTC'S - diagnostic trouble codes stored in the BCM .

The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
The BCM controls the windshield wiper motor through two output controls, controlling two different PCB relays which control the desired wiper speed, high or low.

The PCB relay's are non- servicable , replace fuse box . Soldered in Your best bet mit be to take it to a qualified repair shop .
Are you talking about the front wiper fuse? It's in the under hood fuse block. Hopefully the lid on the under hood fuse block will tell you which fuse is which. Or, your owners manual may have a fuse box legend that will show you which fuse is which.
In my wiring diagram, it appears the front wiper fuse supplies voltage for both the front wiper and washer.
The fuse box is located down or just above where a driver puts their left foot, under the steering well and below the coin box. According to ABMforum.com: "The front wiper rear wiper and washers are on separate fuses (15A WSH front and rear washers 25A WIP front wiper 15A RR WIP rear wiper)."
The breaker is grey in color and goes into the fuse box located above the radiator. If you don't have them go back to the dealer to get them and have them install them.
The power distribution box in the engine compartment # 6 , 30 amp mini - fuse , front wiper motor , front wiper relay , front washer pump , FEM ( also # 7 , 25 amp mini - fuse , rear wiper etc. ) The owners manual shows to disconnect your battery cables before servicing anything in the PD BOX
your relay could be shorted which makes the fuse keep blowing
My wife has a 08 Fox and her front wipers stopped working it's just a fuse in bank 7 a 10 amp just replace with a new one or swap for the 10 amp fuse in bank 11 (just a warning lamp for the handbrake) until you get a new one. ;-)
