The wiper arm hinge and tension spring are concealed on the underside of the wide end of the arm, while integral latch features (3) concealed on the underside of the narrow end of the wiper arm accept the pivot pin of the matching molded plastic wiper blade unit.The rear wiper arm cannot be adjusted or repaired. If damaged or ineffective, the entire wiper arm unit must be replaced.
