Ford Fiesta Mk7 Door Window Outer Weatherstrip Rear Right O/S BA61-A25860-AA

Ford Fiesta Mk7 Door Window Outer Weatherstrip Rear Right O/S is an original body component designed for precise installation on the rear passenger side. It ensures a tight seal for the window, limits the ingress of water and contaminants into the door interior, and improves the cabin's acoustic comfort. Thanks to the factory fit, installation is predictable, and the fitment with the window and door panel remains consistent with Ford standards.

Purpose and function in the Ford Fiesta Mk7 body

The presented weatherstrip belongs to the Window seals and moldings group and is dedicated to the rear right door window of the Ford Fiesta Mk7. The component operates at the interface between the glass and the outer edge of the door panel, creating a barrier against water, mud, road salt, and fine debris that could accelerate corrosion and wear of the window regulator mechanism.

A properly selected weatherstrip profile stabilizes the window during up-and-down movement, limiting vibrations and unwanted play. This is important for both the durability of the guides and driving comfort – it reduces cabin noise and the risk of rattles and knocks within the door area.

Construction, fitment, and installation

The Ford Fiesta Mk7 Door Window Outer Weatherstrip Rear Right O/S has been designed as a component with a precisely replicated door edge shape. This means that the contact line with the sheet metal and the glass is factory-defined, which facilitates installation and allows for maintaining the original geometry of the gap between the window and the panel.

Key design features of this component include:

• a profile matched to the rear right side of the body,
• a characteristic edge finish that works with the window,
• a solution designed to operate in variable weather conditions.

By maintaining the original geometry, the weatherstrip works with the factory door mounts, allowing for installation without the need for body modifications. A correctly installed component restores the tightness and aesthetics of the vehicle's side line.

Benefits of using an original outer window weatherstrip

Using a dedicated outer window weatherstrip in the Ford Fiesta Mk7 brings a number of practical operational benefits:

• limiting water ingress into the door interior, which reduces the risk of corrosion and electrical system problems in the door,
• better protection of the window regulator mechanism against dirt,
• improvement of acoustic comfort inside the vehicle by reducing wind noise,
• maintaining a consistent visual line of the side body section.

A component from this group is particularly important when replacing a window, repairing a door after a collision, or when removing the effects of long-term use in harsh weather conditions. Selecting the correct weatherstrip for the specific installation location (rear, right side) minimizes the risk of leaks and accelerated wear.

Characteristics of the used product

The offered weatherstrip is a used component, which in practice means it comes from vehicle dismantling and may show signs of normal wear. This type of part is an attractive alternative to new components, especially when you want to maintain the original manufacturing standard while optimizing repair costs.

In the case of elements such as outer window weatherstrips, it is crucial to maintain the proper profile and material flexibility so that after installation, it is possible to achieve the appropriate pressure against the window and door panel. Choosing an original Ford component helps maintain the factory operating parameters of the window system.
