Purpose and vehicle placement

The presented seal has been designed specifically for the rear left door window of the Ford Fiesta ST model. Its placement in this part of the body means the component is responsible for:

• stable window guidance within the door channel,
• reducing wind noise at higher speeds,
• protecting the interior from rainwater and dirt,
• maintaining proper window pressure against the door frame.

Due to its correct profile, the seal works in harmony with the window lifting mechanism, which translates into smoother operation and less strain on moving parts.

Technical characteristics and construction

The Ford Fiesta St Door Window Glass Run Seal Gasket Rear Left N/S belongs to the Window seals and trims group, meaning it has been developed for long-term performance in varying weather conditions. The component's construction is optimized for:

• resistance to UV radiation and temperature fluctuations,
• maintaining flexibility in both low and high temperatures,
• precise adhesion to the door and window edges,
• reducing the transmission of vibrations from the body to the glass.

A properly selected seal cross-section helps maintain even pressure along the entire length, which is important for both sealing and acoustic comfort inside the vehicle.

Product condition and benefits of using OEM parts

The offered seal is a used component, which in practice means an economical replacement option while maintaining parameters close to factory specifications. Compared to aftermarket replacements, using an original Ford part promotes:

• better fit to the shape of the door frame and window,
• preservation of factory assembly clearances,
• reduced risk of improper door closing or window operation,
• maintenance of material consistency with other body seals.

For the user, this means stable performance in the long term and less need for assembly adjustments after replacement.

Why it is worth using this seal in a Ford Fiesta ST

Using the correct window seal in the rear left part of the body has a direct impact on the daily comfort of using the car. Replacing a worn component with an original seal for the Ford Fiesta ST allows you to:

• reduce wind noise heard in the cabin,
• limit the risk of window fogging resulting from leaks,
• protect upholstery and door components from moisture,
• maintain the aesthetic appearance of the window edge and door frame.

For workshops and individual users, this is a practical way to restore factory driving comfort without the need to interfere with the door structure.
