Purpose and compatibility with Ford Focus Mk3
The presented window is dedicated to the five-door version of the Ford Focus Mk3 and has been designed as a component for the rear right door. Its placement on the passenger side in the rear of the vehicle ensures a proper fit with the door frame, the window lifting mechanism, and factory seals.
The AS2 marking indicates the use of glass with appropriate light transmission and safety parameters, typical for side windows in modern passenger cars. As a result, the window meets the requirements for user protection and driving comfort.
Technical and functional characteristics
The Ford Focus Mk3 rear right door window is manufactured as a component matched to the factory body contour, which facilitates installation in existing mounting points. The design, intended for use with the standard window regulator, ensures smooth operation in the guides and stable seating in the door frame.
As a part from the Car windows category, this component contributes to:
- lateral structural rigidity of the door,
- proper air circulation when the window is opened,
- reduction of noise and vibrations transmitted to the cabin.
The appropriate edge profile allows for correct adhesion to the seals, which helps maintain body tightness and limits the ingress of water and contaminants into the door interior.
Condition, origin, and benefits of choosing a used part
The offered window is a used component, sourced from vehicle dismantling, which allows for maintaining the factory fit characteristic of original Ford components. Choosing such a part is a cost-effective solution while also being consistent with the principles of sustainable vehicle maintenance – it reduces raw material consumption and supports the reuse of functional components.
For owners of cars from years similar to the Focus Mk3, the topic of refreshing a vehicle using original components from the secondary market may be particularly interesting – this is described in more detail in the article The second life of a youngtimer – how used car parts rejuvenate cars from 1998–2012, which shows practical scenarios for modernization and repair.
Practical installation tips and application
When replacing the rear right door window, it is recommended to check the condition of the guides, seals, and the window lifting mechanism. Proper installation includes:
- thorough cleaning of the door frame from remnants of the old glass or contaminants,
- checking the geometry of the hinges and the door lock,
- verifying the operation of the window regulator for smooth movement.
Doors prepared in this way allow for the full utilization of the offered window’s properties, minimizing the risk of rattles, leaks, or excessive stress on the glass during operation.
