🔧 Altima - Side View Mirror Replacement

You’ll remove the inner door trim, unplug the mirror wiring (if equipped), unbolt the mirror from the door, then install the new mirror and reassemble. The key is protecting the door panel clips and supporting the mirror so it doesn’t drop and chip paint.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours (each side)

Quick questions (so I match your setup): (1) Are your mirrors power-adjust or manual? (2) Are you replacing the entire mirror assembly or just the mirror glass?

⚠️ Safety & Precautions

• Work on a level surface, key out of the ignition, and keep the window fully down on the door you’re working on.
• If your mirror is power-adjust, disconnect the negative battery cable to avoid accidental shorting while unplugging connectors.
• Use plastic trim tools, not a screwdriver, to avoid cracking trim and scratching paint.
• Support the mirror with one hand as you remove the last nut so it doesn’t fall.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the inside mirror sail panel

• At the top-front corner of the door (inside), pry off the small triangular trim cover using a plastic trim removal tool.
• If it feels stuck, work around the edges gently to pop the clips free. Slow, steady pressure prevents cracks.

Step 2: Remove the power window switch panel

• Pry up the switch panel in the armrest using a plastic trim removal tool.
• Unplug the electrical connector(s) by pressing the tab and pulling straight out (use a pick tool to help lift stubborn tabs).

Step 3: Remove door panel screws

• Remove the Phillips screw(s) in the armrest/handle area using a Phillips screwdriver #2.
• If there’s a small cover hiding a screw, pop the cover with a pick tool, then remove the screw with the Phillips screwdriver #2.

Step 4: Release the door panel clips and lift the panel off

• Start at the bottom edge of the door panel. Slide a plastic trim removal tool between the panel and the door metal and pop the clips free, one by one.
• Once the clips are loose, lift the door panel straight up to unhook it from the top window ledge.
• Disconnect any remaining connector(s) and the inner handle cable if equipped (use needle-nose pliers only if needed and be gentle).

Step 5: Peel back the vapor barrier near the mirror area

• Carefully peel back the plastic moisture barrier at the front-upper corner of the door using your hands and a plastic trim removal tool.
• Try not to tear it; it prevents water leaks and wind noise.

Step 6: Unplug the mirror connector (power mirrors)

• Find the mirror wiring connector inside the door near the mirror mounting area.
• Press the lock tab and unplug it by hand (use a pick tool to help depress the tab if needed).
• If your mirror is manual-adjust: there may be no connector—skip this step.

Step 7: Remove the mirror mounting nuts

• Hold the mirror from the outside with one hand.
• Use a 10mm socket, 3" extension, and 1/4" drive ratchet to remove the three mirror mounting nuts.
• Keep the nuts—many replacement mirrors do not include new hardware.

Step 8: Remove the mirror assembly

• Pull the mirror away from the door from the outside.
• If it’s a power mirror, feed the wiring grommet and connector through the opening carefully.
• Wipe the mounting surface with shop rags so the new mirror sits flush.

Step 9: Install the new mirror assembly

• Position the new mirror on the door and start all three nuts by hand to avoid cross-threading.
• Use a 10mm socket and 1/4" drive ratchet to snug the nuts evenly.
• Use an inch-pound torque wrench (20–200 in-lb) with a 10mm socket: Torque to 65 in-lb (7.3 N·m).
• If power mirror: plug the connector back in until it clicks.

Step 10: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place by hand. If the adhesive won’t stick, apply vapor barrier butyl adhesive.
• Reconnect all electrical connectors and any handle cable.
• Hang the door panel on the top window ledge and push downward to seat it.
• Press around the perimeter to snap the clips back in.
• Reinstall door screws using a Phillips screwdriver #2.

Step 11: Reinstall trim pieces

• Reconnect and snap the window switch panel back in using your hands.
• Snap the mirror sail panel back in place.
• Remove the painter’s tape.

✅ After Repair

• If you disconnected the battery, reconnect it using a 10mm socket.
• Test mirror operation (power adjust), and confirm the glass is stable and doesn’t shake at idle.
• Close the door and check for wind noise; if you hear a new whistle, the sail panel or vapor barrier may not be seated.
• Verify the window and door lock switches work before you fully finish.
