Purpose and fitment for Ford Focus Mk2

The described window is designed as a component mounted in the rear left area of the Ford Focus Mk2 body, in the passenger door on the left side of the vehicle. The construction is based on factory dimensions and geometry, which allows for maintaining the correct body line, tightness, and compatibility with original guides, seals, and the window lifting mechanism.

The component is dedicated to the diesel engine version, which facilitates part selection when repairing vehicles used intensively, e.g., in fleets or for daily urban and extra-urban use.

Technical characteristics of the AS3 window

The window belongs to the AS3 type, which means tinted glass with increased user comfort. This type of solution:

• reduces interior heating on sunny days,
• improves visual comfort for passengers in the back seat,
• supports privacy inside the cabin,
• maintains a consistent, factory look of the side bodywork.

Thanks to the use of appropriate glass thickness and structure, the window works with factory seals and guides, which is important for tightness, noise reduction, and the proper operation of the lifting mechanism.

Condition, origin, and benefits of choosing a used OEM part

The component comes from disassembly and is offered as a used original Ford window. In practice, this means factory fitment to the body, compliance with manufacturer standards, and the preservation of performance parameters intended for this model. Compared to low-quality replacements, the original glass fits better into the body line and works with existing door components.

Choosing a used OEM part is also a real saving when repairing a vehicle – especially in the case of daily-driven diesel cars, where both cost and durability matter.

Safety, comfort, and utility aspects

The tinted rear left window affects passenger travel comfort by limiting exposure to solar radiation and improving thermal conditions inside. At the same time, transparency and visibility are maintained within the range provided by the manufacturer, which is important for driving safety.

Proper fitment to the door frame and factory mounts helps maintain body tightness, reduce air noise, and ensure the proper operation of the window opening and closing mechanism. Thanks to this, replacing damaged glass with an original used component allows for restoring full functionality of the side body area without the need for additional modifications.
