• A trim tool is a plastic pry tool used to remove clips without damaging panels.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Protect the Door Paint

• Use 1-inch painter's tape around the mirror base on the outside of the door.
• This protects the paint if the old mirror shifts during removal.
• Take your time here.

Step 2: Remove the Interior Sail Trim Panel

• The sail trim panel is the small triangular plastic cover inside the door, directly opposite the mirror.
• Use a plastic trim removal tool to gently pry the triangular sail trim away from the door.
• Pull straight outward to release the clips.
• If equipped with a small tweeter speaker, unplug the speaker connector by pressing the locking tab with a small flathead screwdriver.

Step 3: Check Mirror Connector Access

• Look behind the sail trim opening for the mirror electrical connector.
• If the connector is visible, press the connector tab with a small flathead screwdriver and unplug it.
• If the connector is lower inside the door, continue to Step 4 to loosen the door panel for access.

Step 4: Loosen the Front Upper Door Panel Area if Needed

• Use a plastic trim removal tool to remove the small trim cover inside the door pull handle.
• Use an 8mm socket or Phillips screwdriver, depending on fastener style, to remove the door pull fastener.
• Use a plastic trim removal tool around the upper front edge of the door panel to release only the clips needed for hand access.
• You do not usually need to fully remove the door panel for this mirror replacement.
• Do not yank the panel.

Step 5: Unplug the Mirror Electrical Connector

• Use your fingers or a small flathead screwdriver to press the mirror connector locking tab.
• Pull the connector straight apart. Do not pull on the wires.
• If the connector is clipped to the door, release the clip using a plastic trim removal tool.

Step 6: Remove the Mirror Mounting Nuts

• Support the outside mirror with one hand.
• Use a 10mm socket, 6-inch extension, and 1/4-inch ratchet to remove the mirror mounting nuts.
• There are typically three mounting nuts behind the sail trim area.
• Use a magnetic pickup tool if a nut drops inside the door.

Step 7: Remove the Old Mirror

• From outside the door, gently pull the mirror away from the door.
• Feed the wiring harness and connector through the door opening by hand.
• Check that the old foam gasket came off with the mirror. Remove stuck gasket pieces by hand if needed.

Step 8: Install the New Mirror

• Feed the new mirror wiring connector through the door opening by hand.
• Place the new mirror against the door and make sure the gasket sits flat.
• Start all mounting nuts by hand first to avoid cross-threading.
• Use a 10mm socket, 6-inch extension, and torque wrench inch-pound 20-120 in-lbs to tighten the nuts evenly.
• Torque to 9 Nm (80 in-lbs)

Step 9: Reconnect the Mirror Wiring

• Push the mirror electrical connector together until it clicks.
• Use a plastic trim removal tool to secure the harness clip back into the door if equipped.
• Make sure the wiring is not pinched by the door panel or sail trim.

Step 10: Reinstall the Door Trim

• If you loosened the door panel, press the panel clips back into place by hand.
• Use an 8mm socket or Phillips screwdriver to reinstall the door pull fastener.
• Snap the handle trim cover back in by hand.
• Reconnect the tweeter speaker connector if equipped.
• Press the triangular sail trim panel back into place by hand until the clips seat fully.

Step 11: Reconnect Battery and Test

• If disconnected, use a 10mm socket to reconnect the negative battery cable.
• Turn the ignition on and test mirror adjustment using the mirror switch.
• If equipped, test the heated mirror by turning on the rear defrost.
• Remove the 1-inch painter's tape from the outside of the door.
