What This Product Does:

• This end cap covers the mounting point of the rear wiper arm, providing a finished, clean appearance and protecting the pivot/nut of the wiper arm from the elements (water, dirt, corrosion).
• It helps maintain the aesthetic of the vehicle’s rear window area, hides the fastening hardware, prevents dirt ingress and supports longevity of the wiper arm mount.
• Because it’s a cosmetic/finishing piece, it contributes to the overall visual quality and can prevent corrosion or wear of the wiper arm pivot point by sealing the joint.

Symptoms / Signs You Might Need To Replace It:

• The cap is missing, cracked, faded or broken, leaving the wiper arm nut or pivot exposed to corrosion.
  
• The wiper arm looks unfinished or the finish/interior of the cap appears damaged, which can detract from the rear window area’s appearance.
  
• You notice corrosion or rust around the wiper arm mounting point — missing or damaged cap may have allowed moisture ingress.
  
• You’ve replaced or serviced the rear wiper arm and want to restore all original parts including the finishing cap, especially on a well-presented or restored vehicle.
• The rear wiper arm nut appears exposed or the cap is loose — replacing the cap ensures correct sealing and fitment.

Why Replacement Matters:

• Preventing moisture/dirt from entering the wiper arm mount area can pre-empt corrosion, loosening or wear of the wiper arm mounting hardware.
• For someone performing restoration, repair or washer/wiper maintenance on the rear window, replacing this cap ensures the job is finished to original standard.
