NISSAN 80860-VD22B Front Right Door Vapor Barrier

This genuine Nissan (SKU: 80860-VD22B) front right vapor barrier is a premium-quality, original OEM part that plays a vital role in protecting the vehicle interior and the door trim panel. The vapor barrier is positioned between the inner metal frame of the front right door and the interior door card.

Technical Specifications and Features:

• Fitting Position: Front right door (passenger side).
• Material: High-tensile, moisture-resistant polyethylene (PE) film resistant to temperature fluctuations and mechanical wear.
• Moisture Protection: Effectively prevents rainwater and moisture entering the door cavity from penetrating the passenger compartment.
• Dust and Wind Protection: Minimizes draft and exterior dust intrusion, improving cabin comfort and acoustics.
• Electrical Component Protection: Shields wiring harnesses, connectors, the central locking motor, and speakers located inside the door from corrosion and short circuits.

Function and Signs of Failure:

The vapor barrier is most frequently damaged during maintenance or repairs of internal door components (such as replacing the window regulator, door lock actuator, or speaker) if the adhesive is improperly detached or the liner is torn. A damaged film may result in the following symptoms:

• Water accumulation in the front right footwell carpet.
• Dampness, staining, or warping at the lower section of the interior door trim.
• Increased window fogging and cabin humidity, especially during wet weather.
• Elevated wind noise and dust ingress while driving.

To ensure a complete seal and maintain a leak-free cabin, it is recommended to replace a damaged or degraded moisture barrier with a new, genuine Nissan part and secure it using an appropriate butyl-based sealant tape.
