Ford C-Max Mk2 Door Window Seal Glass Run Channel Rear Left N/S AM51-R25825

Ford C-Max Mk2 Door Window Seal Glass Run Channel Rear Left N/S is a precisely fitted component from the Window seals and trims category, designed for installation in the rear left door window. Proper sealing of this body area reduces noise, improves acoustic comfort, and helps maintain the cabin's integrity. Thanks to the preservation of factory geometry, the seal interacts with the glass and door frame in a predictable and stable manner.

Purpose and vehicle placement

The presented seal is dedicated for installation in the rear left part of the body, in the door and window area. This placement means the component works in direct contact with the side window, door frame, and bodywork, being responsible for:

• limiting the ingress of water and moisture into the door interior,
• reducing wind noise at higher speeds,
• stable guidance of the window edge in its extreme position. Thanks to the correct profile, the seal helps maintain the proper contact line between the glass and the frame, which translates into more predictable door closing and vehicle comfort.

Technical characteristics and fitment

The rear left door window seal has been designed as a component compatible with the factory Ford body construction. The appropriate cross-sectional geometry, corner shape, and routing along the door frame perimeter allow for installation without the need for modifications or forced fitting. This solution is particularly beneficial when:

• replacing a worn or leaking seal,
• performing post-accident repairs in the rear door area,
• eliminating whistling and wind noise appearing after painting or door adjustment. A properly selected seal profile promotes even pressure along its entire length, which helps maintain stable sealing under various operating conditions.

Component condition and practical application

The offered seal is a used component, which in practice means a real opportunity to reduce repair costs while maintaining the original design and fitment. In many cases, using a part from dismantling allows for restoring proper door sealing without the need to invest in a new component, while maintaining compliance with the factory design. Such a solution is particularly beneficial when:

• leaks appear in the area of the rear left window,
• an increase in noise from the rear door side is noticeable,
• after body and paint repairs, it is necessary to restore proper window adhesion.

Benefits of using a dedicated seal

Using a dedicated rear left door window seal in a Ford C-Max Mk2 allows for several significant operational benefits:

• Better cabin sealing – limiting the ingress of water, dust, and air drafts into the interior.
• Improved acoustic comfort – reduction of noise in the rear part of the body.
• Stable window guidance – lower risk of vibrations and unwanted play while driving.
• Consistency with factory design – no need for adaptation or modification of the door frame. For the user, this means more predictable door and window behavior, as well as a reduction in the risk of repeated service interventions in this area.
