How to change the rear wiper on your 2008 Nissan Pathfinder
Release the old blade
Lift the wiper arm off the window. On many vehicles the wiper arm will not come very far off the window. Grasp the wiper arm with one hand and rotate the blade directly toward you.
Remove the wiper
The blade will release from the wiper arm. Gently pull it straight out and away.
Position the new blade
Place the small bar attachment on the new wiper blade into the hook on the wiper arm.
Lock the blade into place
Rotate the blade away from you and it will snap into place.
Your wiper has been installed. Gently rest the wiper back against the rear window.
