🔧 Altima - Side View Mirror Replacement

Replacing the side view mirror means removing the interior trim near the mirror, unplugging the mirror wiring (if equipped), and swapping the mirror assembly. This is usually straightforward, but taking your time with the door panel clips prevents broken trim.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• ⚠️ Work on level ground and keep the window fully up until you’re ready to remove the door panel.
• ⚠️ If your mirror is power/heated, disconnect the battery negative cable before unplugging connectors.
• ⚠️ Support the mirror with your hand when removing the last nut so it doesn’t fall and chip paint.
• ⚠️ Use plastic trim tools, not a screwdriver, to avoid cracking panels.

• 🪟 Lower the window about halfway before removing the door panel (gives you a safe handhold later).
• 🔋 If power/heated mirror: use a 10mm socket to disconnect the battery negative cable and wait 2 minutes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Protect the paint and prep the area

• Use painter’s tape to mask the door area around the mirror base.
• Place a shop rag on the door sill to catch dropped screws.

Step 2: Remove the inner mirror “sail” trim panel

• Use a flat plastic trim removal tool to gently pry off the triangular trim at the front top of the door (inside, by the mirror).
• Pry close to the clips, not the edge.

Step 3: Remove the door panel (needed to unplug the mirror)

• Use a pick tool to lift the small covers hiding screws in the door pull/handle area (if equipped).
• Use a Phillips #2 screwdriver to remove the door pull/armrest screws.
• Use a flat plastic trim removal tool to pop the door panel clips around the edges (you’ll feel them “snap” free).
• Lift the whole door panel upward to unhook it from the window ledge.
• Disconnect connectors:
  • Use the pick tool to release electrical connector locks (power windows/locks).
  • If there’s a mechanical door-handle cable, use needle-nose pliers to help rotate the cable end out of its slot.
• Set the panel somewhere safe where it won’t get stepped on.

Step 4: Peel back the moisture barrier (water shield)

• Use your hands and a plastic trim tool to carefully peel the plastic moisture barrier back near the mirror area.
• Try not to tear it; it prevents leaks.

Step 5: Unplug the mirror wiring (if equipped)

• Find the mirror connector inside the door near the mirror mount.
• Use a pick tool to lift the lock tab, then unplug the connector by hand.

Step 6: Remove the mirror mounting nuts

• Hold the mirror with one hand from the outside.
• Use a 10mm socket with a 1/4" ratchet and extension to remove the three mounting nuts.
• Pull the mirror away from the door and feed the wiring through the hole (if equipped).

Step 7: Install the new mirror

• Feed the mirror wiring through the door opening (if equipped), and seat the mirror on the door.
• Thread the nuts on by hand first to avoid cross-threading.
• Use a torque wrench and 10mm socket to tighten the mirror nuts: Torque to 7.2 Nm (64 in-lb).
• Plug in the mirror connector until it clicks (if equipped).

Step 8: Reinstall the moisture barrier and door panel

• Press the moisture barrier back into place by hand. If the adhesive won’t stick, apply butyl adhesive.
• Reconnect all door panel connectors (and the handle cable if equipped) by hand.
• Hang the door panel on the top window ledge, then press the clips in around the edges using firm palm pressure.
• Reinstall screws using a Phillips #2 screwdriver, then snap the screw covers back in.
• Snap the triangular sail trim back on by hand.

Step 9: Reconnect battery (if disconnected)

• Use a 10mm socket to reconnect the battery negative cable.
