Buyer's checklist
What to check before buying a used front door assembly
- Verify door shell dimensions, body line pressings, and trim moldings, especially when comparing 2-door, 4-door, crew cab, and extended cab body variants.
- Check internal electrical harness connectors, verifying power mirror options (heating, turn signals, blind spot indicators), speaker wiring, and door lock modules.
- Inspect bottom drain holes and lower inner hem flanges for bubbling paint or structural rust common in wet climates.
- Confirm whether the assembly includes glass, window regulator, latch mechanism, exterior handle, and interior panel or if it is a bare door shell.
