⚠️ Safety & Precautions

• ⚠️ Work on a level surface with the car in Park and the ignition OFF.
• ⚠️ Disconnect the negative battery terminal before unplugging door wiring to reduce risk of shorts and warning lights.
• ⚠️ Support the door panel so it doesn’t hang by the wiring harness.
• ⚠️ Don’t pull on wires; pull on connectors (the plastic plugs).
• ⚠️ If your mirror has the passenger-side camera, handle it gently and keep the lens clean.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the mirror “sail” trim (small triangle cover)

• Use a trim removal tool set (plastic) (specialty) to gently pry off the interior triangular trim at the front top corner of the door (by the mirror).
• If it has a small clip tether, release it with a pick tool (specialty).

Step 2: Remove the door panel fasteners

• In the interior door pull/handle pocket area, remove the cover with a trim removal tool set (plastic) (specialty).
• Remove the exposed screw(s) using a Phillips #2 screwdriver.
• At the bottom/edge of the door panel, remove any additional screw(s) using a Phillips #2 screwdriver.

Step 3: Pop the door panel clips loose

• Slide a trim removal tool set (plastic) (specialty) between the door panel and the metal door.
• Pry near each clip location until it pops free (you’ll hear a snap). Work around the sides and bottom.
• Pry near clips, not in the middle.

Step 4: Lift the door panel up and disconnect wiring

• Lift the whole door panel straight up to unhook it from the window ledge.
• Support the panel with one hand (or rest it on a box), then unplug connectors by pressing the tab and pulling the plug:
  • Use a pick tool (specialty) only if the tab is stubborn (don’t break it).
• If equipped with a door handle cable, unhook it carefully (a cable is a small wire with a plastic end that snaps into the handle).

Step 5: Peel back the vapor barrier (water shield)

• Near the mirror corner, gently peel back the plastic water shield enough to access the mirror mounting area.
• If the sticky seal (butyl) stretches, use shop towels to keep it clean and reuse it, or plan to replace it with butyl tape.

Step 6: Unplug the mirror harness

• Locate the mirror electrical connector near the front upper door area.
• Press the connector lock tab and unplug it (use needle-nose pliers only to assist grip, not to crush it).
• Pull on the connector, not the wires.

Step 7: Remove the mirror mounting nuts

• Hold the mirror with your outside hand so it doesn’t fall or scratch paint.
• Use a 10mm socket, 6" socket extension (1/4"), and 1/4" drive ratchet to remove the three mounting nuts.
• Remove the mirror from the outside of the door.

Step 8: Transfer parts if needed (gasket/trim pieces)

• If the new mirror does not include the foam gasket, transfer/install the mirror mounting gasket so it seals against wind and water.
• Wipe the door mounting surface clean with shop towels.

Step 9: Install the new mirror

• Set the new mirror in place from the outside and align the studs through the door.
• Start all three nuts by hand first to avoid cross-threading.
• Tighten the nuts using a 10mm socket and 1/4" drive ratchet, then finish with a torque wrench (in-lb capable) to: Torque to 9 Nm (80 in-lb).

Step 10: Reconnect mirror wiring (and camera/turn signal if equipped)

• Plug the mirror connector back in until it clicks.
• If your mirror has a passenger-side camera, make sure the connector is fully seated and routed exactly like before so it won’t rub the window track.

Step 11: Reinstall the vapor barrier

• Press the plastic water shield back onto the door using the existing adhesive.
• If the seal is damaged or won’t stick, apply butyl tape and press the shield firmly all the way around.

Step 12: Reinstall the door panel

• Reconnect all door panel connectors (window switch, lock switch, etc.) by pushing them in until they click.
• Hang the top of the door panel onto the window ledge first, then press downward to seat it.
• Use your palm to press around the edges to snap all clips back in.
• Reinstall screws using a Phillips #2 screwdriver (snug only). If using a torque wrench: Torque to 2 Nm (18 in-lb).
• Reinstall the sail trim by pressing it back into place.

Step 13: Reconnect the battery

• Reconnect the negative terminal using a 10mm socket and tighten securely.

✅ After Repair

• Turn the ignition ON and test mirror movement in all directions using the mirror switch.
• If equipped, test mirror heat (rear defogger on) and verify the glass warms after a few minutes.
• If equipped, test the mirror turn signal and blind spot camera image; confirm the picture is stable and not angled oddly.
• Drive at highway speed and listen for wind noise; if present, recheck gasket seating and nut torque.
