NISSAN 80861-VD22B Front Left Door Vapor Barrier

The genuine NISSAN (SKU: 80861-VD22B) front left vapor barrier (garnish / protective cover) is a premium quality, original factory OEM part that plays a crucial role in protecting the vehicle's interior cabin. This specialized protective element is located between the internal structure of the front left door and the interior door trim panel.

Function and Importance:

The primary function of the vapor barrier is to prevent moisture, humidity, wind, and dust from penetrating from the inner cavities of the door into the passenger cabin. In addition, it contributes to the vehicle's sound dampening (NVH – noise, vibration, and harshness reduction), ensuring a more comfortable ride. Without an intact seal, the door trim panel can absorb moisture, resulting in mold, unpleasant odors, and corrosion of sensitive electrical components (such as window regulator motors, speakers, and door lock assemblies).

Technical Specifications:

• Manufacturer: NISSAN (Original OEM)
• Part Number: 80861-VD22B
• Fitting Position: Front left door (interior side)
• Material: High-density, tear-resistant polyethylene (PE) film / durable plastic composite
• Resistance: Excellent water, moisture, and temperature resistance
• Mounting: Fastened using dedicated butyl sealing tape or adhesive

Signs of Damage or Aging:

Damage to the vapor barrier film most frequently occurs during door repairs, window regulator replacements, or aftermarket audio upgrades when the film is improperly peeled back or torn. Typical symptoms of aging or damage include:

• Appearance of moisture or water stains at the bottom of the front left door trim or on the floor carpet.
• Excessive fogging of windows and windshield due to moisture accumulating inside the passenger compartment.
• Increased wind noise and exterior road noise entering the cabin while driving.
• Oxidation and malfunctions of electrical connectors located inside the door shell.

To ensure a perfect fit and fully restore factory sealing efficiency, the use of genuine OEM replacement parts is recommended.
