The front door component carrier does exactly what its name describes. It carriers the window regulator, glass, and mirror, and must be removed to work on these systems. This article will show you how to remove the carrier and all its components from the door.

To begin you will need to remove the door panel. Please see our article on removing your front door panel and complete the work there before starting this project.

With the door panel off you will be looking at the door with the membrane still in place (red arrow).
