ok today i did some tinkering with the wiper and motor cause my ford edge wiper doesnt hit the top arc ...
heres the fix
take the hatch plastic off and it will expose the motor
theres 3 screws on the motor ... 1 at the bottom and 2 on top
well its upside down but heres a pic
the 2 that are circled are held on by sheet metal brackets that flex
push gently on these 2 and bend em towards the hatch and then experiment
go little by little
spray the window with water and turn the wiper on ... if it doesnt hit ... then push some more ... mine is PERFECT now ... all the time i spent ... 30 mins tinkering ... pays off ... HOPE THIS HELPS EVERYONE ....
