Purpose and fitment for Ford Fiesta Mk6

The presented window is designed for installation in the front left door of the sixth-generation Ford Fiesta, in the position defined as front – left side of the vehicle. The appropriate edge profile and correct glass thickness allow for proper interaction with guides, seals, and the window regulator, which minimizes the risk of jamming and leaks.

Original Ford glass guarantees the maintenance of factory transparency and color parameters, which is important for both driving safety and the consistent appearance of the entire line of windows in the car.

Glass characteristics and user comfort

The window is made of AS2 tempered glass in a subtle green tint. This type of glass:

• provides adequate light transmission while limiting excessive interior heating,
• is characterized by a controlled breakage pattern, which increases user safety,
• maintains stable optical properties, reducing image distortion in mirrors and when observing the surroundings.

As a result, the driver and passenger receive a balanced compromise between visibility, thermal comfort, and safety.

Installation zone and technical aspects

The window is intended for installation in the front left door, which means its shape, bending radii, and the placement of mounting points are adapted to this specific position. Proper seating in the door frame allows for maintaining:

• correct pressure against the seals along the entire perimeter,
• smooth operation throughout the full range of window movement,
• visual consistency with the vehicle's other side windows.

The item comes from the Car Windows group, which facilitates the selection of compatible components, such as guides, seals, or lifting mechanisms, in the case of broader service work within the door area.

Condition, origin, and benefits of choosing used glass

The offered window is a used part, which allows for a significant reduction in repair costs compared to new replacements, while maintaining factory origin and fitment. In practice, this means:

• original glass geometry consistent with the Ford design,
• no need for modifications to mounts or guides,
• the possibility of an economical repair after mechanical damage or a collision.

With proper installation by an experienced service center, the window ensures stable operation in daily use, without a negative impact on the door mechanism's performance or body tightness.
