⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging the mirror connector to reduce short-circuit risk.
• ⚠️ Wear safety glasses and gloves. Door trim clips can pop loose suddenly.
• ⚠️ Support the mirror with one hand while removing the final nut so it does not fall and scratch the paint.
• ⚠️ Do not pry against painted surfaces with metal tools.
• ⚠️ If your replacement mirror includes a blind-spot indicator, confirm it matches your original mirror equipment before installation.

📋 Before You Begin

• Apply painter’s tape 2-inch width around the outside mirror base if the painted area is close to the mirror housing.
• A plastic trim removal tool is a non-metal pry tool used to release interior panels without scratching them.
• A panel clip remover is a fork-shaped tool that pulls plastic clips straight out so they are less likely to break.
• Disconnect the negative battery cable using a 10mm socket before unplugging mirror wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the Battery

• Open the hood and locate the battery.
• Use a 10mm socket and ratchet wrench to loosen the negative battery terminal clamp.
• Move the cable away from the battery post so it cannot touch the battery while you work.

Step 2: Protect the Paint

• Use painter’s tape 2-inch width around the outside base of the side mirror.
• Place a microfiber towel along the top of the door trim and outer door edge.
• Tip: Tape prevents accidental scratches.

Step 3: Remove the Interior Mirror Trim Cover

• At the inside front corner of the door, locate the small triangular trim cover behind the mirror.
• Use a plastic trim removal tool to gently pry the trim cover away from the door.
• Pull it straight outward by hand after the clips release.
• If a small connector or tweeter speaker is attached, use a small flat-blade screwdriver to press the connector tab and unplug it.

Step 4: Remove the Window Switch Trim

• Use a plastic trim removal tool to lift the front window switch trim from the armrest.
• Use a small flat-blade screwdriver to press the connector lock tab.

Step 9: Remove the Mirror Mounting Nuts

• Support the outside mirror with one hand.
• Use a 10mm socket, 6-inch socket extension, and ratchet wrench to remove the mirror mounting nuts from inside the door.

Step 10: Remove the Old Mirror

Step 11: Install the New Mirror

• Feed the new mirror wiring harness through the door opening by hand.
• Seat the mirror gasket flat against the outside of the door.
• Hold the mirror in place with one hand.
• Start the mirror mounting nuts by hand to avoid cross-threading.

Step 12: Connect and Test the Mirror

• Plug in the mirror connector by hand until it clicks.
