Doors Buying Guide

Whether you're replacing a complete door assembly or just the exterior handle, this guide helps you understand what to look for and what to expect. It also covers the motor that powers automatic sliding doors.

A door assembly is the complete door frame including the inner structure, outer skin, window frame, and all the sheet metal as one unit. This is what you buy when mounting surfaces, hinges, or the overall door structure are damaged. Used doors may not include door glass, the window regulator, the trim panel, the mirror, the exterior handle, weatherstripping, or any wiring. Please check the listing or call our sales team if you aren't sure what is included.

Front Door Assembly

The front door (driver or front passenger) is shorter than the rear door on 4-door vehicles. Always specify driver/left or passenger/right.

Rear Side Door Assembly

The rear side door is the rear passenger door on 4-door vehicles. On minivans and some SUVs this may be a powered sliding door. Specify side and confirm whether yours is a hinged or sliding door.

Back Door Assembly

The back door is the rear hatch/liftgate on hatchbacks, SUVs, and vans. It typically includes the window frame but not the glass.

When replacing with a bare door assembly, you may have to transfer the following components from your original door if they aren't included in the assembly:

  • Door glass (verify it fits the replacement frame)

  • Window regulator and motor

  • Interior trim panel

  • Exterior door handle

  • Side view mirror

  • Weatherstripping

  • All wiring and connectors

This work is significant — factor it into your total repair time and cost estimate.

Used doors are typically sold in the donor vehicle's color. If it doesn't match your vehicle, the door will need painting. Budget for a body shop paint match unless the color is a near-exact match and you're comfortable with minor variation.

Before accepting a used door:

  • Open and close it to check the swing and latch engagement

  • Check the window frame for squareness (a bent frame means misaligned glass)

  • Inspect the bottom of the door for rust along the drain holes

  • Verify all holes align (mirror, handle cutouts)

The exterior door handle is the outside grip used to open the door. Failure modes include cracked handles, broken internal springs, and worn finishes. Handles are position- and side-specific. Many handles do not include the lock cylinder or any keyless-entry sensor — verify what's included and whether painting is required to match body color.

Electric Door Motor

The electric door motor powers automatic sliding door systems on minivans and some SUVs, driving the door open and closed along its track. It is specific to the door side and vehicle platform. It does not include the door panel, latch, or track assembly.
