Ok, first item is to check the fuse, which you have done. Just to make sure, it is in position 180, bottom row, third from the left, a 20 amp fuse. After checking the fuse, there is not to much else that can be done. The service manual has the normal items of checking the wiring from the wiper/washer switch to the washer pump. The washer pump is attached to the bottom of the fluid reservoir under the left (drivers side)front fender. You have to remove the fender splash shield to get access. Just out of curiosity, does the washer pump work for the rear windows? The same pump works for both front and back, it just reverses direction when pumping to the rear windows. One last item, do you have any fault codes DTC's? Front washer fault code for wiring is B2114 and for rear wring is B2115. You can check for codes by using the self test read out on the dash. Press and hold the trip odometer reset button (the one on the left of the LCD readout) and turn the ignition switch to the start position. Release the reset button when the LCD readout says tESt (takes about 5 seconds). The first display is gAgE (it tests all the gauges). Then press the reset button 8 more times to see if there are any DTC's.
If there are none, it will read NONE.
Turn the ignition key off to end the test.
Good Luck.
