This procedure replaces the complete driver-side or passenger-side mirror assembly. The inner door trim panel must be loosened or removed to reach the electrical connector and three mirror retaining nuts.

Assumption: Replacement mirrors match your Trax’s original power, heating, folding, and turn-signal features.

Difficulty Level: Beginner | Estimated Time: 1-1.5 hours per side

⚠️ Safety & Precautions

• ⚠️ Switch the ignition off and keep the key away from the vehicle before disconnecting the mirror.
• 🧤 Wear gloves because the door panel edges and damaged mirror glass can be sharp.
• 🪟 Support the mirror before removing its final nut so it cannot fall against the door or window.
• 🔌 Battery disconnection is not normally required. Do not switch the ignition on while door wiring is disconnected.
• 🚫 Do not pull the door panel away forcefully; wiring remains attached behind it.

📋 Before You Begin

• 🅿️ Park your Trax on level ground, select Park, apply the parking brake, and lower the window completely.
• 🔑 Switch the ignition off and move the key or transmitter away from the vehicle.
• 🛡️ Use 25mm automotive masking tape around the mirror base and upper door edge to protect the paint.
• 📦 Unpack the replacement mirror and compare its connector, three mounting studs, gasket, housing shape, and installed features with the old mirror.
• 🌡️ If working in cold weather, warm the interior first. Cold plastic trim clips break more easily.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the Interior Mirror Trim Cover

• Use a plastic trim-removal tool to pry the triangular trim cover inward from the upper-front corner of the door.
• Release its clips gradually and lift the cover away. A trim-removal tool is a nonmetal pry tool that helps prevent scratches.
• Do not use excessive force if the cover remains trapped by the main door panel.
• Keep each fastener grouped by location.

Step 2: Remove the Door-Pull Fastener Cover

• Use a small flat-tip screwdriver to lift the small cover inside or beneath the interior door-pull handle.
• Wrap the screwdriver tip with automotive masking tape before touching visible plastic.
• Remove the exposed screw with a Torx T20 screwdriver or the exposed bolt with a 7mm socket and 1/4-inch-drive ratchet, according to the original fastener fitted.

Step 3: Remove the Interior Handle Trim and Remaining Fasteners

• Use a plastic trim-removal tool to release the trim around the interior release handle.
• Remove the exposed door-panel fastener with a 7mm socket and 1/4-inch-drive ratchet.
• Check the bottom edge of the panel and remove any additional factory 7mm fastener with the same socket.
• Place all removed fasteners where they cannot fall into the door.

Step 4: Release the Door Trim Panel

• Insert a plastic trim-removal tool between the lower door panel and the metal door shell.
• Work around the bottom and both sides, releasing one push-in retainer at a time. A retainer is the plastic clip securing the panel to the door.
• Use both hands to lift the panel straight upward and release it from the window ledge.
• Support the panel instead of allowing it to hang from its wires or cables.

Step 5: Disconnect the Door-Panel Connections

• Use a small flat-tip screwdriver to depress the locking tabs, then unplug the window-switch and door-lock electrical connectors by their plastic bodies.
• Release the interior handle cable from its bracket by hand, then rotate the cable end out of the handle lever.
• Set the door panel on a clean, padded surface.
• Use a plastic trim-removal tool to peel back only the upper-front corner of the water deflector. Do not tear or stretch it.

Step 6: Disconnect the Mirror Wiring

• Locate the mirror wiring connector near the upper-front section of the door.
• Use a small flat-tip screwdriver to release the connector lock, then unplug the connector by hand.
• Release the mirror harness from any door-mounted clips by hand or with a plastic trim-removal tool.
• Note the harness routing so it can be installed away from the window mechanism.

Step 7: Remove the Old Mirror Assembly

• Hold the mirror securely with one hand from outside the door.
• Use a 10mm deep socket, 6-inch extension, and 1/4-inch-drive ratchet to remove the three mirror retaining nuts.
• Keep the socket level so a nut does not fall inside the door. Use a magnetic pickup tool if one is dropped.
• Pull the mirror straight outward while guiding its wiring and connector through the opening.
• Remove any gasket material left on the mounting surface by hand. Do not scratch the paint.

Step 8: Install the Replacement Mirror

• Confirm the replacement mirror gasket lies flat and fully covers the mounting base.
• Guide the electrical connector through the door opening and place all three studs through their mounting holes.
• Start all three nuts by hand to prevent cross-threading.
• Use a 10mm deep socket, 6-inch extension, and inch-pound torque wrench to tighten the nuts evenly in stages.
• Torque the mirror retaining nuts to 9 Nm (80 in-lbs).
• Do not overtighten the nuts; excessive force can crack the mirror base or distort the door sheet metal.

Step 9: Connect and Route the Wiring

• Route the harness through the original clips by hand, keeping it clear of the moving window glass and regulator.
• Push the mirror electrical connectors together until the lock clicks.
• Press the water deflector back into its original butyl adhesive using gloved fingers. Butyl is the reusable sticky seal around the deflector.
• Seal the deflector completely to prevent water from reaching the interior trim.

Step 10: Test the Mirror Before Reassembly

• Temporarily reconnect the window-switch connector by hand.
• Switch the ignition to On without starting the engine.
• Use the factory mirror control to move the glass up, down, left, and right.
• If equipped, verify the mirror turn signal. Heated-glass operation may take several minutes with the rear defogger switched on.
• Switch the ignition off and disconnect the temporary switch connection before reinstalling the panel.

Step 11: Reinstall the Door Trim Panel

• Reconnect the interior handle cable and all electrical connectors by hand. Confirm every connector lock clicks.
• Replace any damaged trim-panel retainer by hand before fitting the panel.
• Lower the upper edge of the panel over the window ledge, then align its retainers with the door holes.
• Press around the panel perimeter firmly with your hands until every retainer engages.
• Install the original door-panel fasteners with a 7mm socket and 1/4-inch-drive ratchet or Torx T20 screwdriver, matching the fastener removed from each location.
• Tighten the trim fasteners only until snug; do not crush the plastic mounting points.
• Snap the handle trim and fastener covers into position by hand.

Step 12: Reinstall the Mirror Trim Cover

• Align the triangular mirror trim cover with its clips.
• Press it evenly into place by hand until all clips engage.
• Remove the automotive masking tape and inspect the door finish.

✅ After Repair

• ✅ Operate the mirror through its full adjustment range and listen for smooth motor operation.
• 🔆 Check the mirror turn signal and heated glass if those features are installed.
• 🪟 Raise and lower the window completely. Stop immediately if the glass contacts wiring or makes an unusual noise.
• 🔒 Test the window switch, door lock, interior release handle, and speaker before driving.
• 🛣️ Adjust the mirror from the normal driving position and verify that the housing remains secure during a short road test.
• 💧 After rain or washing, inspect the lower door trim for moisture that could indicate an improperly sealed water deflector.
• 🧭 No programming, scan-tool setup, or ADAS calibration is normally required for a matching standard mirror assembly.
