Buyer's checklist
What to check before buying a used door mirror
- Confirm the feature set: power fold, heated, blind-spot monitoring, turn signal, and auto-dim vary by trim.
- Test the power adjustment motor if possible — a mirror that moves on one axis but not the other needs a motor replacement.
- Check the connector pin count. Mirrors with more features have more pins, and a mismatch means missing functions.
- Look for cracks on the mirror glass backing plate. A cracked plate causes the glass to vibrate at highway speeds.
