🔧 Forester - Side View Mirror Replacement

This repair replaces the complete outside side-view mirror assembly on your Forester. The mirror is bolted to the front door from behind the interior door trim panel, so the door panel must come off carefully to reach the mirror connector and mounting nuts.

Difficulty Level: Beginner-Intermediate | Estimated Time: 1-2 hours per side

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door electrical connectors to reduce the chance of short circuits.
• ⚠️ Your Forester Limited mirror may include heat, turn signal, blind spot warning indicator, and power folding depending on equipment. Replace with a matching mirror assembly.
• ⚠️ Do not pull hard on the door panel. It has wiring and plastic clips behind it.
• ⚠️ Support the mirror with one hand when removing the last mounting nut so it does not fall and scratch the door.
• ⚠️ If replacing both mirrors, do one side at a time so you can use the other side as a reference.

📋 Before You Begin

• 🅿️ Park your Forester on level ground and set the parking brake.
• 🔑 Turn the ignition off and remove the key fob from the vehicle.
• 🪟 Lower the front window on the side you are repairing. This gives you more room to hold the mirror.
• 🔋 Use a 10mm wrench to disconnect the negative battery cable, then wait at least 2 minutes before unplugging door connectors.
• 🧰 A trim removal tool is a plastic pry tool used to remove panels without scratching them.
• 🧰 A panel clip remover is a fork-shaped tool that pops plastic clips out without breaking them.
• 🧼 Apply painter’s tape around the mirror base on the painted door edge to protect the paint.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Protect the Door Paint

• Use painter’s tape around the outside mirror base where it meets the door.
• Place a microfiber towel over the upper door edge to protect the paint while you work.
• Take photos before removing parts.

Step 2: Remove the Interior Door Handle Trim

• Use a plastic trim removal tool to gently pry off the small trim cover inside the interior door handle area.
• Use a Phillips #2 screwdriver to remove the screw behind the trim cover.
• Keep the screw in a small cup so it does not get lost.

Step 3: Remove the Door Pull Screw Cover

• Use a small flat-blade screwdriver to carefully lift the screw cover in the door pull pocket.
• Wrap the screwdriver tip with tape if needed to avoid marks.
• Use a Phillips #2 screwdriver to remove the screw inside the door pull pocket.

Step 4: Release the Door Trim Panel Clips

• Use a plastic trim removal tool at the lower rear edge of the door panel.
• Gently pry outward until the first clip pops loose.
• Use the panel clip remover to work around the bottom and sides of the panel.
• Do not pry at the top edge yet. The top edge hooks over the window ledge.
• Slow pressure breaks fewer clips.

Step 5: Lift Off the Door Trim Panel

• Use both hands to lift the door panel straight upward off the window ledge.
• Hold the panel close to the door because wiring is still attached.
• Use a small flat-blade screwdriver to press the locking tabs on the electrical connectors.
• Unplug the window switch connector and courtesy light connector if equipped.
• Set the door panel on a clean towel.

Step 6: Remove the Mirror Sail Trim

• The sail trim is the small triangular plastic cover inside the door, directly behind the mirror.
• Use a plastic trim removal tool to gently pry the sail trim away from the door.
• If a tweeter speaker is attached, use a small flat-blade screwdriver to release its connector tab and unplug it.

Step 7: Disconnect the Mirror Wiring

• Find the mirror wiring connector inside the upper front area of the door.
• Use a small flat-blade screwdriver to depress the connector lock if it is tight.
• Unplug the mirror connector by pulling on the connector body, not the wires.
• Release the wiring harness clips from the door using the panel clip remover.

Step 8: Remove the Mirror Mounting Nuts

• Support the outside mirror with one hand.
• Use a 10mm socket, ratchet handle, and 6-inch extension to remove the mirror mounting nuts.
• Remove the lower nut first, then the upper nuts.
• Keep holding the mirror while removing the final nut.
• Typical Subaru outside mirror nut torque on installation is Torque to 7.5 Nm (66 in-lbs).

Step 9: Remove the Old Mirror

• From outside the door, gently pull the mirror straight away from the door.
• Feed the wiring harness through the hole in the door.
• Check that the old mirror gasket did not stick to the door.
• Use a microfiber towel to clean the mounting surface.

Step 10: Install the New Mirror

• Make sure the new mirror gasket is seated flat on the mirror base.
• Feed the mirror wiring harness through the door opening.
• Position the mirror studs through the mounting holes.
• Install the mounting nuts by hand first to avoid cross-threading.
• Use a 10mm socket, 6-inch extension, and torque wrench to tighten the nuts evenly to Torque to 7.5 Nm (66 in-lbs).
• Do not overtighten mirror nuts.

Step 11: Reconnect the Mirror Wiring

• Plug the mirror connector into the door harness until it clicks.
• Use your fingers to route the harness back into the original clips.
• Make sure the wiring will not touch the window glass or regulator parts inside the door.

Step 12: Test the Mirror Before Reassembly

• Use a 10mm wrench to temporarily reconnect the negative battery cable.
• Turn the ignition to ON without starting the engine.
• Use the mirror switch to test up, down, left, and right adjustment.
• Test mirror heat using the rear defogger button if safe to do so.
• Test the turn signal indicator and blind spot warning indicator if equipped.
• Turn the ignition off and use a 10mm wrench to disconnect the negative battery cable again before final panel installation.

Step 13: Reinstall the Mirror Sail Trim

• If equipped, plug the tweeter speaker connector back in until it clicks.
• Align the sail trim clips with the door holes.
• Press the sail trim into place by hand until all clips snap in.

Step 14: Reinstall the Door Trim Panel

• Hold the door panel close to the door.
• Reconnect the window switch connector and courtesy light connector by hand until they click.
• Hang the top of the door panel over the window ledge.
• Line up the panel clips with the holes in the door.
• Press around the sides and bottom with your palm until all clips snap in.

Step 15: Reinstall Door Screws and Covers

• Use a Phillips #2 screwdriver to reinstall the door pull screw.
• Use a Phillips #2 screwdriver to reinstall the interior door handle screw.
• Snap both screw covers back into place by hand.
• Use gentle pressure. These covers are plastic and can crack.

Step 16: Reconnect the Battery

• Use a 10mm wrench to reconnect the negative battery cable.
• Tighten the terminal snugly. Do not overtighten it.
• Start the vehicle and verify the window switch, door lock switch, and mirror controls work.
