🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk and Locate the Access Area

• Open the trunk lid fully.
• Go to the side where the turn signal bulb is being replaced.
• Look at the trunk side trim directly behind the rear lamp assembly.
• Use a trim panel removal tool to gently loosen the trunk liner or access flap.
• Work slowly to avoid breaking clips.

Step 2: Move the Trunk Trim Aside

• Use a flat-blade screwdriver or trim panel removal tool to remove any plastic push clips if needed.
• A push clip is a small plastic fastener that holds trim panels in place.
• Pull the trunk liner back just enough to reach the bulb sockets behind the tail lamp.
• Do not yank the trim; just flex it gently out of the way.

Step 3: Identify the Rear Turn Signal Bulb Socket

• Find the bulb socket for the rear turn signal inside the rear lamp housing.
• The turn signal bulb socket is typically the socket for the amber flashing bulb.
• If unsure, turn the hazard lights on briefly, watch which socket flashes, then turn the lights off again before removing it.
• Use safety glasses while working close to the trunk trim and lamp housing.

Step 4: Remove the Bulb Socket

• Grip the turn signal bulb socket by hand.
• Rotate the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the rear lamp housing.
• No torque spec applies because the socket is hand-tight only.
• Do not pull on the wires.

Step 5: Remove the Old Bulb

• Put on clean nitrile gloves.
• Pull the old rear turn signal bulb straight out of the socket by hand.
• If the bulb is stuck, gently wiggle it while pulling straight out.
• Check the socket for heat damage, corrosion, or melted plastic.

Step 6: Install the New Bulb

• Hold the new rear turn signal bulb, amber with clean nitrile gloves.
• Push the new bulb straight into the socket until it seats fully.
• Do not force it at an angle.
• If you touched the glass, wipe it clean with a dry lint-free cloth before installing.

Step 7: Reinstall the Bulb Socket

• Insert the bulb and socket back into the rear lamp housing.
• Turn the socket clockwise by hand until it locks in place.
• Make sure it is snug and even.
• No torque spec applies because this is a hand-locking bulb socket.

Step 8: Test the Turn Signal

• Turn the ignition to ON without starting the engine.
• Switch on the turn signal for the side you repaired.
• Walk to the rear and confirm the bulb flashes normally.
• Also press the hazard switch and confirm both rear turn signals flash.
• If the signal flashes very fast, the bulb may not be seated correctly or the wrong bulb may be installed.

Step 9: Reinstall the Trunk Trim

• Turn the ignition and lights back off.
• Move the trunk liner back into position by hand.
• Use the trim panel removal tool or your fingers to reinstall any plastic push clips.
• Press each clip until it sits flush with the trim.
• Close the trunk and check that nothing is pinched.

✅ After Repair

• ✅ Test the left turn signal, right turn signal, and hazard lights.
• ✅ Confirm the dash indicator flashes at a normal speed.
• ✅ Check the lamp housing from outside to make sure the bulb is bright and amber.
• ✅ If one bulb failed, replacing both rear turn signal bulbs is recommended so brightness and age match.
