How to change the rear wiper on your 1990 Subaru Justy

Most blades are held in place with a tiny clip. Push that clip up towards the arm and push the blade backwards, as if you were sliding it down the wiper arm.

Once the blade is free from the hook, push the blade a few inches down the arm to disconnect it. When the hook is fully visible, the blade will be free and can be taken off.

Position the new blade so that the the hook is pointing at the wiper attachment. The hook will go over the top of the attachment.

Pull the blade toward the end of the arm. You'll hear a click when it locks into position.

You're all finished replacing the blade.
