Wiper blade, Rear
Genuine Porsche rear wiper blade for Porsche 964 / 993 Coupe applications. It replaces the wiping component on the rear wiper arm to clear water from the rear screen.

Fits:
Porsche 964 1989 – 1994
Porsche 993 1994 – 1997 Coupe

What Is This Part?
This is the replaceable blade in the rear window wiper assembly. It attaches to the rear wiper arm, which moves it across the outside of the glass. The blade provides the wiping edge, while the arm and drive mechanism position and move it. Blade renewal is appropriate when the wiping edge has deteriorated and the supporting arm remains serviceable.

What Does This Part Do?

• Clears water: Sweeps rain and spray from the area covered by the rear wiper.
• Provides the wiping contact: Places the blade edge against the rear screen as the arm moves.
• Works with the rear wiper assembly: Follows the movement of the arm and its drive mechanism.

Why Replace This Part?

A worn or damaged wiping edge can leave smears or uncleared sections on the rear screen. Replacing a deteriorated blade renews the part that contacts the glass without unnecessarily replacing a serviceable arm or motor. Persistent poor wiping should also prompt inspection of the glass, arm and blade attachment rather than assuming the blade is the only cause. Streaking and noise are recognised indications that wiper condition needs attention. 

When to Replace This Part?

• Persistent smearing: Streaks remain after the rear screen and blade edge have been cleaned.
• Visible edge damage: The wiping edge is split, torn or uneven.
• Skipping or chatter: The blade does not travel smoothly across wet glass; check the arm and screen condition as well.
• Poor contact: Sections of the blade lift away from the glass or leave an unwiped area.
• Damaged attachment: The blade cannot be secured correctly to the arm.

Cleaning can resolve contamination-related streaking or jumping, so assess the blade again before deciding replacement is necessary.

Where Is This Part Fitted?
Location: On the rear wiper arm, against the outside surface of the rear window.

FAQs

• Why might a new blade still wipe poorly?
  Check rear screen cleanliness, arm condition and whether the blade sits evenly against the glass. Contamination can interfere with wiping even when the blade is serviceable. ()
• Does the rear wiper arm need replacing at the same time?
  Not automatically. Inspect it for corrosion, stiff pivots, looseness or inadequate contact with the screen, and replace it only if its condition warrants it.
