Study Notes

Vehicle Door Designs

Variety of models results in different door designs among vehicle manufacturers.
Passenger cars and trucks generally have similar door designs; minivans commonly feature electric sliding doors activated by handles or key fob buttons.
Electric-powered sliding doors present unique challenges for collision repair technicians.

Types of Doors

Two basic designs for passenger car doors: framed and frameless.
Framed Doors:
- Surround window glass with a metal frame that aids in alignment.
- Seal against the door opening when closed.
- Sliding doors with roll-down windows fall into this category.
Frameless Doors:
- Glass extends above the door (when rolled up) without a surrounding frame.
- Requires the glass to seal against weatherstripping to prevent leaks.

Basic Parts of a Vehicle Door

Door Frame: Main steel structure that supports various components like hinges, glass, and handles.
Door Skin: Outer panel covering the door frame, made from materials such as steel, aluminum, fiberglass, or plastic.
Door Glass: Must provide good visibility and can be operated up and down.
Door Glass Channel: U-shaped guide lined with low-friction material, facilitating the movement of the glass.
Window Regulator: Mechanism that moves the glass up or down when the window handle or button is operated.
Door Latch: Engages with the door striker on the vehicle body, securing the door when closed.
Inner and Outer Door Handles: Use linkage rods to activate the door latch for opening.
Door Trim Panel: Attractive cover for the inner door frame, can house elements like inner handles and speakers.
Moisture Barrier: Plastic layer between inner trim panel and frame, protecting against wind noise and moisture.
Weatherstripping: Seals around the door or opening; compresses when the door is closed to prevent air and water leaks.
Rearview Mirror: Typically mounted outside the door frame, adjustable by controls on the dash or door panel, mostly power-operated rather than manual.
