When inspecting a vehicle door, what else may need to be examined?

In a comprehensive vehicle door inspection, it is crucial to assess all components that can impact both functionality and structural integrity. The door skin is the outermost layer that provides the first line of defense against environmental elements, while the window channel is vital for ensuring the smooth operation of the window and preventing any water intrusion. Additionally, the frame that supports the inner door panel and arm rest is essential for the overall strength and stability of the door assembly.

Examining all these components together allows for a thorough understanding of the door's condition. Overlooking any single aspect may result in missing underlying issues that could affect the vehicle's safety and performance. This holistic approach ensures that repairs can be accurately diagnosed and addressed, making the correct answer that all these parts need to be examined.
