Rear wiper help Clio 182

[Gibbo4k]

Hello all.
My 182 rear wiper has lost it's park as it does its sweep of the screen then on return to rest it passes its park spot touches the boot slightly then back up to park.
I've tried the motor on another car and is fine on their so wondered what controls this. I've searched and found some say a relay and some say a uch unit ? Has anyone else had this problem at all and did you manage to fix it.
Thanks for any advice

Take the wiper arm off and re position.

i would but then it looks silly sitting an inch higher up the screen than its meant to be.. the car didnt have a wiper on when i got it but prefered it looking more original..
