Hi Jane I'll beat Thomas to it
nice and easy
Lift the wiper off the screen all the way till it stays up.....
look for the 2 serrated tabs (one at the top and one at the bottom of the wiper mount or each side (depending on how you look at it)
press these two tabs together and fold upwards and away then pull up to remove the top clip......
a video paints a million words however.....

take a min or 2 to load up in media player if that doesn't work click the blue text which says
This is a video, click on the thumbnail to download
and save it to your pc then play it that way !
just try to put the wiper down a bit more carefully than i did (one handed)
