- Work carefully around the door trim and glass to avoid scratching the paint or window.
- Use a plastic trim tool, not a screwdriver, on interior panels to prevent damage.
- If the mirror has an integrated turn signal, unplug it gently before removing the assembly.

📋 Before You Begin

🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the interior sail panel
- Use a plastic trim removal tool to pry off the small triangular trim panel at the front upper corner of the door.
- Pull it straight away from the door to release the retaining clips.
- Keep pressure even to avoid cracking the clip tabs.
Step 2: Disconnect the mirror connector if equipped
- If your mirror is power-operated, heated, or has a turn signal, unplug the electrical connector by hand.
- If the connector is tight, gently release the lock tab with a small pick or your fingernail.
- On a manual mirror, there will be no connector to unplug.
Step 3: Remove the mirror mounting nuts
- Use a 10mm socket, ratchet, and short extension to remove the three mirror nuts from inside the door.
- Hold the mirror with your other hand as the last nut comes off.
- Torque to 7 N·m (62 in-lbs) during installation.
Step 4: Remove the old mirror from the door
- Carefully lift the mirror assembly away from the door from the outside.
- Check that the foam seal comes off cleanly and does not tear into the door opening.
Step 5: Install the new mirror
- Position the new mirror on the door studs from the outside.
- Start all three nuts by hand first using the 10mm socket only after the threads are seated correctly.
- Reconnect the electrical connector if equipped.
- Tighten the nuts evenly with the torque wrench to 7 N·m (62 in-lbs).
Step 6: Reinstall the sail panel
- Align the trim panel clips and press the panel into place by hand.
- Make sure it sits flush with the door trim.
Step 7: Test the new mirror
- If equipped, test mirror adjustment, heating, and turn signal function.
- Check from inside and outside to make sure the mirror is secure and does not move.
✅ After Repair
- Confirm the mirror glass adjusts smoothly through its full range.
- Verify the mirror housing is tight and the trim panel does not rattle.
- If the vehicle has a power mirror, make sure the connector is fully seated before closing the door panel fully.
- Road test briefly and recheck for wind noise around the mirror base.
