next thing to do was to remove the wiper of the rear window. Before any of you tackle it if you have not already done it, it is a hard job !! first thing i did was to take the black plastic cover off the inside of the boot
next i unscrewed the motor for the wiper blade and disconnected the motors power cable
then soaked where the wiper is attached with wd40 overnight (use alot )
in the morning use some elbow grease and pullll !!! and off it came and then removed the wiper motor and finished off by using a 13mm blanking grommet to cover the whole where the wiper was
