🔧 F-150 - Side View Mirror Replacement

This repair replaces the outside side view mirror assembly on your F-150. The mirror is held to the front door with mounting nuts behind the interior door trim panel, so the door panel must be loosened or removed to access the connector and fasteners.

Difficulty Level: Beginner | Estimated Time: 45-90 minutes per side

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging the mirror connector to prevent electrical shorts.
• ⚠️ Support the mirror with one hand while removing the last nut so it does not fall and scratch the door.
• ⚠️ Wear safety glasses and gloves. Door panel clips can pop loose suddenly, and the door shell has sharp edges.
• ⚠️ Do not pry against painted metal with a screwdriver. Use plastic trim tools to avoid scratches.
• ⚠️ If your mirror has blind spot monitoring, puddle lamps, heat, or turn signal wiring, make sure the replacement mirror has matching features.
