Located inside the door, it helps guide the window regulator mechanism during operation, ensuring controlled movement as the window is raised or lowered.

Not intended for Coupe models. Confirm compatibility using the vehicle VIN before ordering.

What Does It Do?

The guide rail supports the window regulator mechanism, helping maintain the correct movement and alignment of the door glass.

It works alongside the regulator, window guides and electric motor to allow smooth opening and closing of the window.

• Difficulty raising or lowering the glass

Why Does It Fail?

Common causes include:

• Wear from repeated window operation
• Corrosion or moisture exposure
• Bent or damaged guide surfaces
• Loose mounting points
• Incorrect window alignment

When Should It Be Replaced?

Replace the guide rail if:

• The window moves unevenly or becomes difficult to operate
• The rail is bent, corroded or damaged
• Excessive movement is present in the regulator mechanism
• The mounting points are damaged
• The original rail cannot maintain correct alignment

Checks & Installation

Inspect the window regulator, guide rollers, mounting points and door glass alignment before installation.
