Steve. lift up the flip up cover on the base of the wiper arm and undo the nut inside. the arm is on a spline and should be teased off, this can be very difficult. you can use WD40 or buy a wiper puller, £10. remove the plastic cowel inside the boot lid, screws or clips. unplug the wiring from motor. remove the 3 fixing bolts and lift out motor. when the new motor is fitted before fitting the arm make sure it is in its resting position. hope this is of use.
