Door card clip, GREY.
Porsche Genuine OE Door interior trim panel clip. This small but essential component is used to secure the interior door trim panel (door card) to the door frame on select Porsche 911 and Boxster models, preserving fitment, finish and noise-free operation. It is supplied in the correct grey colour used on many factory interiors.
Sold individually, 8 required per door card.

This trim panel clip functions as a fastener/retainer that holds the interior door card to the sheet-metal door shell. It ensures that the trim panel stays snugly in place, prevents rattling or sagging over time, and supports correct panel alignment and gap integrity. While small in size, these clips are critical for a quality interior install and are commonly replaced when door panels are removed for service or repair.

Functions & Technical Role:
•  Interior trim retention: Secures the door card to the door shell
•  Anti-rattle support: Helps stop vibration and panel noise
•  OEM-matched fit: Clip shape and size engineered for Porsche door components
•  Quick service access: Enables repeat panel removal and re-installation without damage
•  Durable construction: Made to withstand repeated door use over many years

Interior clips like this are small, but they play a big role in panel retention, noise reduction, and interior quality perception. Over time, plastic clips can become brittle or break when door panels are removed for access to speakers, wiring or window regulators. Replacing them with genuine Porsche OE clips ensures precise engagement, correct fit, and long-term reliability - keeping your interior looking and feeling factory-finished.

Door card clip, GREY.
OE Match door trim panel clip, direct-fit interior fastener that restores secure retention of door trim on Porsche 996 and Boxster (986) models. Helps keep panels aligned, reduces noise, and maintains factory interior quality.
Sold individually, 8 required per door card.

The door trim panel clip provides mechanical retention between the interior trim panel (door card) and the underlying door frame structure. It keeps the panel aligned, prevents rattles, and ensures a secure, flush fit with the surrounding interior surfaces.

Function
•  Secures the door trim/interior panel to the door structure
•  Restores proper alignment and fit of door panel assemblies
•  Reduces rattles, vibration, and panel movement

Missing or degraded trim clips can lead to loose, uneven, or rattling door panels, which detract from interior quality and comfort. Replacing old clips with correct OE Match parts restores a firm, factory-like attachment, improves interior finish, and helps prevent panel damage during removal or use.

When to replace:
•  Door trim panel feels loose or rattles
•  Visible broken, cracked, or missing clips
•  During door panel removal or servicing
•  After interior trim or speaker installation
•  When refurbishing or restoring vehicle interior

•  Position: Front left / right door, window lift regulator (cable type), used with the original electric window motor.

Function & Benefits:
•  Provides smooth, controlled raising and lowering of the side window.
•  Maintains correct glass alignment in the guides for proper sealing against wind and water.
•  Restores OEM-style speed, noise levels and reliability of the electric window system.

With age, window regulators commonly suffer from frayed or snapped cables, broken plastic guides or distorted tracks, leading to slow, jerky or inoperative windows. A failing mechanism can allow the glass to drop, jam or sit crooked, causing water ingress, wind noise and security issues.

Replacing the unit with a new regulator restores:
• Reliable window operation from full up to full down
• Correct glass position against the door frame and seals
• Reduced rattles, squeaks and wind noise
• Confidence when using the window frequently

 Typical signs it’s time to replace:
•  Window drops on one side or tilts in the frame
• Grinding, clicking or cable noise inside the door
• Window stops part-way or won’t move at all
• Regulator cables visibly snapped or off the pulleys

About Window Mechanism

Window mechanisms are the core components that allow your Porsche’s windows to move smoothly up and down. Located inside the door panel, these assemblies typically consist of a regulator, cables, pulleys, and guides that work together to raise or lower the glass when activated by the electric window motor and switch.

At Design911, we supply high-quality window mechanism assemblies for all Porsche models - from classic air-cooled 911s to the latest Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is designed to restore precise window movement and perfect alignment, ensuring your car retains its comfort, performance, and style.

What Do Window Mechanisms Do?
The window mechanism (or regulator) transfers motion from the electric window motor to the glass. It ensures smooth, consistent, and balanced movement of the window within the guide rails. Depending on your Porsche model, the system may use a cable-operated, scissor-type, or gear-driven design.

A correctly functioning window mechanism ensures:

  • Smooth and quiet window travel.
  • Secure sealing against wind and rain.
  • Reliable operation for ventilation and safety.

Why Do Window Mechanisms Fail?

Over time, window regulators can wear out due to repeated use, exposure to moisture, and mechanical stress. Common causes of failure include:

  • Broken cables or pulleys: Caused by corrosion or tension fatigue.
  • Worn plastic clips or guides: Often brittle with age or temperature changes.
  • Motor strain: Caused by a stiff or misaligned regulator.
  • Internal gear damage: Resulting in uneven or stuck window travel.

Signs of failure include grinding noises, slow window operation, or glass stuck halfway.

Why Replace Faulty Window Mechanisms?

A failing window mechanism compromises both comfort and safety. A window that won’t close properly can let in rain, reduce security, or fail an MOT test. Replacing a worn mechanism ensures:

  • Restored smooth window movement.
  • Improved cabin comfort and quietness.
  • Proper sealing and protection from elements.
  • Prevention of further motor or switch damage.

Design911 offers OEM-spec and genuine Porsche window mechanisms for an exact fit and long service life — the ideal solution to restore factory-quality operation and appearance.
