⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging mirror wiring.
• ⚠️ Wear safety glasses and gloves. Door trim clips can pop loose suddenly.
• ⚠️ Support the mirror with one hand before removing the final nut so it does not fall and scratch the door.
• ⚠️ If your replacement mirror has blind spot, heat, signal, puddle lamp, or power-fold features, the replacement must match the original equipment.
• ⚠️ Do not pry against painted metal with a metal screwdriver. Use a plastic trim tool.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the window switch trim panel

• Use a trim panel removal tool to gently lift the window switch trim panel from the armrest.
• A trim panel removal tool is a plastic pry tool that helps remove panels without scratching them.
• Use a small flat-blade screwdriver to press the locking tabs on the electrical connectors.
• Unplug the window switch connectors and set the trim aside.
• Tip: Pry gently and evenly.

Step 2: Remove the hidden door panel screws

• Use a small flat-blade screwdriver to remove any small plastic screw covers in the door pull area and lower trim area.
• Use a 7mm socket and 1/4-inch ratchet to remove the small door trim screws.
• Use an 8mm socket and 1/4-inch ratchet to remove the larger door trim screws if equipped.
• Keep the screws grouped by location so they go back in the same holes.

Step 3: Remove the front door trim panel

• Use a trim panel removal tool along the lower edge of the door panel to pop the retaining clips loose.
• Retaining clips are small plastic fasteners that snap the door panel to the metal door shell.
• Once the clips are loose, lift the door panel straight upward to unhook it from the window ledge.
• Use a small flat-blade screwdriver to release any remaining electrical connector locks.
• Set the door panel on a clean surface.

Step 4: Remove the mirror sail trim panel

• Use a trim panel removal tool to gently pry off the small triangular interior trim at the front upper corner of the door.
• This triangular piece is called the sail panel, and it covers the mirror mounting area.
• Pull it straight away from the door so the clips release cleanly.

Step 5: Disconnect the mirror wiring

• Follow the mirror wiring harness from the mirror area to its connector inside the door.
• Use a small flat-blade screwdriver to press the connector lock tab if needed.
• Unplug the mirror connector by hand.
• If the harness is clipped to the door, use a trim panel removal tool to release the harness clips.

Step 6: Remove the old side view mirror

• Hold the mirror firmly from the outside with one hand.
• Use a 10mm socket, 6-inch extension, and 3/8-inch ratchet to remove the mirror mounting nuts from inside the door.
• Remove the final nut slowly while supporting the mirror.
• Pull the mirror straight away from the door and guide the wiring through the opening.
• Tip: Do not drag the studs on paint.

Step 7: Install the new side view mirror

• Guide the new mirror wiring through the door opening by hand.
• Set the mirror studs into the mounting holes.
• Hold the mirror flush against the door while starting the mounting nuts by hand.
• Use a 10mm socket, 6-inch extension, and torque wrench inch-pound to tighten the mirror mounting nuts.
• Torque to 10 Nm (89 in-lbs).
• Do not overtighten. The mirror base and door sheet metal can be damaged.

Step 8: Connect and route the mirror wiring

• Plug the mirror connector in by hand until it clicks.
• Use the original routing path and reinstall any harness clips by hand.
• Make sure the wiring is not pinched near the window track or door panel clips.

Step 9: Test the mirror before reinstalling trim

• Reconnect the negative battery cable using a 10mm socket.
• Temporarily plug the window switch panel back in by hand.
• Turn the ignition on.
• Use the mirror switch to test up, down, left, and right movement.
• If equipped, test mirror heat, turn signal, puddle lamp, and power fold.
• Turn the ignition off after testing.

Step 10: Reinstall the sail trim panel

• Align the triangular sail panel clips with their holes.
• Press the panel into place by hand until it snaps in securely.
• Make sure it sits flat with no gaps.

Step 11: Reinstall the front door trim panel

• Reconnect any door panel wiring by hand.
• Hang the door panel on the upper window ledge first.
• Press around the edges by hand to snap the retaining clips back into the door.
• Use a 7mm socket and 1/4-inch ratchet to reinstall the small trim screws.
• Use an 8mm socket and 1/4-inch ratchet to reinstall the larger trim screws if equipped.
• Torque small trim screws to 2 Nm (18 in-lbs).
• Torque larger trim screws to 3 Nm (27 in-lbs).

Step 12: Reinstall the switch trim panel

• Plug the window switch connectors in by hand until they click.
• Align the switch trim panel with the armrest opening.
• Press it down by hand until the clips snap into place.
• Use a microfiber towel to wipe fingerprints from the mirror glass and door trim.
