FIRST.............. Open the tailgate and try to move the wiper arm, if it's stiff then do the following:

Over time the wiper arm spindle that sits in the tailgate gathers muck and sticks (possible resulting in fuse blowing!).
To clean:
Take the cover off the rear wiper and undo wiper arm.
Using a small screwdriver remove the circlip and undo the large nut holding the wiper arm on
Take the spindle out from the glass, probably be stiff but wiggle it out!
On the spindle is a brass collar, this WILL come off, usually a good soak of WD40 and while holding the spindle with pliers use another set to manipulate the collar off (very stiff but MUST come off to lubricate/clean it)
Once off, wirebrush the spindle and clean the collar inside and out (carb cleaner good for inside), make sure it nice and clean and put a bit of copper-ease on it then re-assemble.
Put it all back together and the wiper should move very easily by hand with tailgate open.
Thats it!.....wipe away
