Rear Window Wiper Arm Assembly for Nissan

This rear wiper arm assembly is a key exterior part that keeps your back glass clear in rain, snow, and road spray ?️. It is needed to hold the wiper blade at the correct angle and pressure so the motor’s movement becomes a smooth, full sweep across the rear window.

How It Works

The arm mounts onto the rear wiper spindle and locks in place with a spline/fastener fit. A built-in spring applies steady tension, pressing the blade evenly on the glass. When the wiper motor rotates, the arm transfers torque to the blade, wiping water and grime away for safer reversing and lane changes.

Signs It’s Worn or Failing

• Uneven wiping, streaks, or missed areas
• Arm feels loose on the pivot or slips while running
• Blade chatter due to weak spring pressure
• Corrosion at the joint causing stiff movement

If You Drive With a Broken Arm

A damaged arm can stop wiping completely, overload the motor, or let the blade scrape and mark the glass ?. Visibility drops fast in bad weather, and the rear wiper system may require more expensive repairs if forced to run.
