Wiper arm, Rear. Porsche 997 MKI / 997 MKII COUPE  ›  99762816901

What This Product Does

The arm transfers movement from the rear wiper motor spindle to the wiper blade. Its sprung construction holds the blade against the glass while allowing it to follow the shape of the rear window.

Functions

• Connects the rear wiper blade to the motor spindle
• Guides the blade across the intended wiping area
• Maintains pressure between the blade and rear glass
• Supports the correct parked position of the rear wiper
  
  

Symptoms of Fault

• Weak or uneven blade pressure against the glass
• Smearing, chattering or an incomplete wiped area
• Corrosion or visible damage to the arm
• A stiff pivot or restricted blade movement
• The arm no longer rests in the correct park position

Why Replacement Matters

A worn, bent or corroded arm can prevent the blade from following the rear glass correctly, even when the blade itself is serviceable. Replacing the faulty arm helps restore the designed wiping path and provides a secure mounting point for the rear blade. Set the park position carefully during fitting and inspect the spindle, fixing nut, cap and blade for wear or damage.
