10mm ring/flat spanner
First remove the plastic drip tray. Next, loosen and remove the centre nut holding the wiper arm. Then pop it off the motor using the spanner.
Next, remove the 3 bolts holding the motor to the support bracket and remove the motor towards the driver's side. Note this is for right hand drive, so LHD cars, remove towards passenger side.
Unclip the wire connector on the motor, throw old motor far away, put connector onto new motor, place new motor in position, tighten bolts up and check wipers.
Time taken: 10 minutes.
Quick and easy.
