It's probably behind the the black plastic driver's side wheel arch, inside the front bumper as on my daughter's 2001 Micra. You have to undo the two 10mm bolts on the underside of the bumper. Then remove a couple of phillips screws up around the edge of the wheel arch. Then peel the wheel arch black plastic into the wheel area to get access to the tank and pump. If you pull the pump out of the tank be ready to get wet. The pump has probably become clogged or jammed but there is no way to clear the pump, you could try tapping the pump on a hard surface(sometimes gets the pump going again but not for long)
