🔧 Focus - Side View Mirror Replacement

On your Focus, the side mirror can be replaced as a complete mirror assembly (the whole unit) or as just the mirror glass (the reflective part). The assembly swap is common after a broken housing; the glass-only swap is common after cracked glass.

Difficulty Level: Intermediate | Estimated Time: 0.5-1.5 hours (per side)

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and remove the key before unplugging mirror wiring.
• ⚠️ Support the mirror with one hand when removing the nuts so it doesn’t fall and chip paint.
• ⚠️ Wear gloves—broken mirror glass is razor-sharp.
• ⚠️ If your mirror has heat/turn signal/indicator wiring, don’t pull on wires—pull on connectors.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the inside sail-panel trim (mirror triangle cover)

• Use a trim removal tool set to gently pry off the small triangular trim panel at the front upper corner of the door (inside, by the A-pillar).
• If it feels stuck, work around the edges—this panel is held by clips.
• Pull straight out to avoid breaking clips.

Step 2: Unplug the mirror electrical connector (if equipped)

• Locate the mirror wiring connector behind the sail-panel area.
• Use a small flat plastic pry tool to lift the lock tab if needed, then unplug the connector by hand.
• If there’s a harness clip, use needle-nose pliers to release it without yanking wires.

Step 3: Remove the mirror mounting nuts

• Hold the mirror on the outside with one hand.
• Use a 10mm socket, 1/4" ratchet, and 3" extension to remove the 3 mounting nuts.
• Set the nuts aside (or replace them if damaged).

Step 4: Remove the mirror assembly from the door

• Carefully pull the mirror away from the door while guiding the wiring through the opening.
• Remove any foam gasket remnants from the door surface by hand (don’t scratch paint).

Step 5: Install the new mirror assembly

• Feed the mirror wiring through the door opening and position the mirror on the studs.
• Hand-thread the 3 nuts first to avoid cross-threading.
• Use a torque wrench (in-lb or Nm range) with a 10mm socket to tighten the nuts: Torque to 10 Nm (89 in-lb).
• Plug the connector back in until it clicks.

Step 6: Reinstall the sail-panel trim

• Line up the clips and press the trim back into place by hand.
• If clips won’t hold, replace them (they’re easy to break once removed).

Optional: Mirror glass-only replacement (if you’re not replacing the whole assembly)

• Use a trim removal tool set to carefully pry the mirror glass outward at an edge until it pops off the backing plate.
• If heated, disconnect the two heater terminals from the back of the glass by hand (note orientation).
• Reconnect heater terminals to the new glass (if equipped), align the center mount, then press evenly until it snaps in.
• Press near the center, not the edges.

• If equipped, verify mirror heat (may take a few minutes), and check the mirror turn signal/indicator operation.
• 🚗 Take a short drive and listen for wind noise—if present, re-check mirror seating and gasket alignment.
