Hi, the fuse for the wiper motor is located in the interior fuse box located in the passenger side front footwell. Fuse 3 is for the wiper motor.
I've attached a diagram of the fuse box and fuse location. If your fuse is good you need to test for power to the wiper motor on the green wire. If there is no power to the motor the problem is with the wiring between the fuse and the motor. The most likely place would be at the flex point at the tailgate hinge.
