Hi
washer motor is on the end of the washer bottle, drivers side behind headlight, to remove washer bottle you have to remove inner wheel arch and about two screws and one bolt bit of a sod to get too, or you can just about get your hand in and pull pump off washer bottle will still have to remove inner wheel arch, our washer pump stopped working i stripped it all out and it turned out to be the fuse blown so check this first.
Best of luck
