🔧 Forte - Side View Mirror Replacement

You can replace the side mirror on your Forte either as a complete mirror assembly (housing + motor + glass) or just the mirror glass. The complete assembly replacement requires removing the door trim panel so you can access the mirror mounting nuts and electrical connector.

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

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before working in the door (side-impact airbag wiring runs through the door).
• ⚠️ After disconnecting the battery, wait at least 3 minutes before unplugging door connectors.
• ⚠️ Support the door panel as you remove it so it doesn’t yank on wiring.
• ⚠️ Don’t fully peel off the vapor barrier (plastic sheet); it prevents water leaks.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm what you’re replacing

• If the housing is cracked, the mirror won’t adjust, or the connector is damaged, replace the full mirror assembly.
• If only the reflective glass is broken and the housing/motor still work, you can replace mirror glass only (see Step 10).

Step 2: Remove the inner mirror “sail” trim

• At the front top corner of the door (inside), pry off the small triangular trim cover using a plastic trim tool.
• Work slowly; it’s held by clips. Pull straight outward to avoid breaking clips.

Step 3: Remove door panel screws

• Use a pick tool to lift the small screw covers in the interior door pull/handle areas (if present).
• Remove the exposed screws using a Phillips screwdriver #2.

Step 4: Release the door panel clips

• Starting at the bottom edge of the door panel, slide a plastic trim tool between the panel and the door and pop the clips free one-by-one.
• Keep the panel close to the door as clips release so it doesn’t bend.

Step 5: Lift the door panel up and disconnect wiring

• Lift the panel straight upward to unhook it from the window ledge.
• Disconnect the power window/lock switch connector(s) by pressing the lock tab with your fingers or a pick tool.
• If equipped with a cable-style interior door handle, release the cable end using needle-nose pliers and rotate the cable housing out of its bracket.
• Set the door panel on your blanket.

Step 6: Peel back the vapor barrier near the mirror area

• Carefully peel the plastic vapor barrier back only in the front upper corner using your hands (no sharp tools).
• If the butyl adhesive won’t stick later, you’ll replace it with butyl tape.

Step 7: Unplug the mirror electrical connector

• Find the mirror harness connector near the mirror mount area.
• Press the tab and unplug it (use a pick tool only if needed).

Step 8: Remove the mirror mounting nuts

• Support the mirror from the outside with one hand (or use painter’s tape to help hold it).
• Use a 10mm socket, ratchet, and 3" extension to remove the three mirror mounting nuts.

Step 9: Install the new mirror assembly

• Feed the mirror harness through the door and position the mirror on the studs.
• Start all three nuts by hand first (prevents cross-threading).
• Use a torque wrench (in-lb) with a 10mm socket to tighten the nuts: Torque to 71 in-lbs (8 Nm).
• Reconnect the mirror electrical connector until it clicks.

Step 10 (Optional): Mirror glass-only replacement

• Skip door panel removal if you are only replacing the glass and the housing is intact.
• Angle the mirror fully inward/down using the mirror switch (or gently by hand if it’s broken).
• Place a microfiber towel under the mirror to catch pieces.
• Use a plastic trim tool to carefully pop the glass off the motor plate (it snaps on).
• If your mirror is heated, pull the two heater terminals off using needle-nose pliers (pull on the connector, not the wire).
• Reconnect the heater terminals (if equipped), align the new glass, and press evenly until it snaps in.

Step 11: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into the butyl. If it won’t seal, apply butyl tape and reseat it.
• Reconnect all door panel electrical connectors and the handle cable (if equipped).
• Hang the panel on the top lip first, then press the clips back in around the edges with your hands.
• Reinstall screws using a Phillips screwdriver #2 and snap the covers back on.
• Reinstall the sail trim by lining up clips and pressing it on by hand.

Step 12: Reconnect the battery

• Use a 10mm wrench to reconnect the negative battery terminal.

• If equipped, test turn signal indicator on the mirror.
• Close the door and listen for rattles; re-seat any loose door clips if needed.
• Drive at 30–45 mph and listen for wind noise (a mis-seated mirror gasket can whistle).
