🔧 Outback - Side View Mirror Replacement

You’ll remove the inside door trim, unplug the mirror wiring, unbolt the mirror from the door, and install the new mirror. This is a straightforward bolt-on job, but you must be gentle with the door panel clips and careful around the side airbag inside the door.

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


⚠️ Safety & Precautions

  • ⚠️ Disconnect the negative battery cable before door trim work; the door contains a side airbag.
  • ⚠️ After disconnecting the battery, wait at least 3 minutes before unplugging any connectors.
  • ⚠️ Support the door panel as you unplug connectors; don’t let it hang by the wiring.
  • ⚠️ Use plastic trim tools to avoid paint and trim damage.
  • ⚠️ Keep the ignition OFF while connectors are unplugged to reduce warning lights.

🔧 Required Tools

You'll need the following tools for this repair:

  • 10mm socket
  • 1/4" drive ratchet
  • 3" extension (1/4" drive)
  • Torque wrench (in-lb capable)
  • Phillips #2 screwdriver
  • Plastic trim removal tool set
  • Pick tool
  • Needle-nose pliers
  • Painter’s tape
  • Shop light
  • Gloves
  • Safety glasses

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Side view mirror assembly (LH or RH, correct options: power/heated/turn signal) - Qty: 1
  • Door trim panel clips - Qty: 2-10
  • Mirror gasket/seal (if not included with mirror) - Qty: 1
  • Butyl tape for vapor barrier (if barrier adhesive tears) - Qty: 1

📋 Before You Begin

  • Park on level ground, shift to Park, and turn the ignition OFF.
  • Lower the window on the side you’re working on (helps handling the panel).
  • Use a 10mm socket to disconnect the negative battery terminal, then wait 3 minutes.
  • Apply painter’s tape along the door edge and mirror area to protect paint.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the small inner “sail” trim panel

  • At the top front corner of the door (inside, by the mirror), use a plastic trim removal tool to pry off the small triangular trim piece.
  • Pull straight outward to avoid cracking it.

Step 2: Remove the door pull/handle trim and screws

  • Use a plastic trim removal tool to pop off the trim cover in the interior door pull (the “grab handle” area).
  • Remove the exposed screws using a Phillips #2 screwdriver.
  • If there’s a small cover behind the interior door release area, lift it with a pick tool, then remove any screw underneath using a Phillips #2 screwdriver.

Step 3: Remove the door panel (trim panel)

  • Slide a plastic trim removal tool under the bottom edge of the door panel and gently pop the retaining clips free.
  • Work around the sides, popping clips one by one (you’ll hear them release).
  • Lift the panel straight up to unhook it from the window channel.
  • Support the panel and unplug connectors (window switch, courtesy light) by pressing the lock tabs; use a pick tool only if needed.
  • If equipped with a cable for the inside handle, note its routing and unhook it carefully (a cable is a steel wire inside a plastic sheath).

Step 4: Peel back the vapor barrier near the mirror area

  • The vapor barrier is the plastic sheet behind the door panel. Carefully peel it back only as much as needed near the mirror mount.
  • If the sticky seal (butyl) stretches, you can re-seal it later; use butyl tape if it tears.

Step 5: Disconnect the mirror wiring connector

  • Find the mirror connector near the upper front of the door.
  • Press the lock tab and unplug it by hand; use needle-nose pliers gently only if it’s stubborn.

Step 6: Remove the mirror mounting nuts

  • Hold the mirror with one hand from the outside so it doesn’t fall or scratch the door.
  • Use a 10mm socket, 1/4" ratchet, and 3" extension to remove the three mirror mounting nuts.
  • Remove the mirror from the outside and guide the wiring through the opening.

Step 7: Install the new mirror

  • Guide the mirror harness through the door opening and seat the mirror on the door.
  • Hand-thread the three nuts to avoid cross-threading, then tighten with a 10mm socket.
  • Final tighten using a torque wrench: Torque to 7.5 Nm (66 in-lbs).
  • Snug only—over-tightening can crack the mirror base.

Step 8: Reconnect wiring and reassemble the door

  • Plug the mirror connector back in until it clicks.
  • Press the vapor barrier back into place; add butyl tape if needed to fully seal.
  • Reconnect all door panel connectors and any handle cable.
  • Hook the door panel onto the top window channel and press down to seat it.
  • Press around the perimeter to snap all clips back in.
  • Reinstall screws with a Phillips #2 screwdriver, then snap the trim covers back on.
  • Reinstall the sail trim by aligning clips and pressing it into place by hand.

Step 9: Reconnect the battery

  • Reconnect the negative battery terminal using a 10mm socket.

✅ After Repair

  • Turn the ignition ON and test mirror movement (up/down/left/right).
  • Test mirror heat (if equipped) and turn signal/puddle light (if equipped).
  • Confirm the window switch, door lock, and interior handle all work normally.
  • Check the mirror sits flush and doesn’t wobble when you gently push on it.
  • If any airbag or warning light appears, recheck connectors and battery connection.
