🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk and Locate the Access Area

• Use the trunk release button or key fob to open the trunk.
• Use a flashlight to look at the inner trunk liner behind the rear lamp assembly.
• The rear turn signal bulb socket is accessed from behind the tail lamp area inside the trunk.

Step 2: Move the Trunk Liner Aside

• Use the trim clip removal tool to gently pry out the plastic trunk liner clips near the lamp area.
• If a clip has a center pin, use a small flathead screwdriver to lift the center pin first, then remove the clip.
• Pull the trunk liner back just enough to reach the bulb sockets.
• Go slow to avoid breaking clips.

Step 3: Find the Rear Turn Signal Bulb Socket

• Use the flashlight to identify the turn signal bulb socket on the rear lamp assembly.
• The turn signal socket is usually the amber bulb position in the rear combination lamp.
• Do not pull on the wiring harness; handle the plastic socket body only.

Step 4: Remove the Bulb Socket

• Use your gloved hand to grip the bulb socket.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.
• No torque spec applies to this twist-lock bulb socket; hand-tight only.

Step 5: Remove the Old Bulb

• Use clean nitrile gloves to grip the old bulb.
• Pull the bulb straight out of the socket if it is a wedge-style bulb.
• If the bulb is tight, gently wiggle it side to side while pulling.
• Do not crush the glass bulb.

Step 6: Install the New Bulb

• Use clean nitrile gloves to handle the new rear turn signal bulb.
• Push the new bulb straight into the socket until it seats fully.
• Make sure the bulb feels secure and does not wobble.
• Clean gloves keep bulbs working longer.

Step 7: Reinstall the Bulb Socket

• Use your gloved hand to insert the bulb socket back into the lamp housing.
• Align the socket tabs with the housing slots.
• Turn the socket clockwise about a quarter turn until it locks.
• Hand-tight only; do not use pliers or force.

Step 8: Test the Turn Signal

• Close the trunk only partway or leave it open safely.
• Turn the ignition to accessory mode or start the vehicle.
• Use the turn signal stalk to test the side you repaired.
• Use the hazard switch to test both rear turn signals if you replaced both bulbs.
• If the bulb does not light, turn the vehicle off and reseat the bulb and socket.

Step 9: Reinstall the Trunk Liner

• Use your hands to move the trunk liner back into place.
• Use the trim clip removal tool or your fingers to reinstall the plastic clips.
• Press each clip firmly until it sits flat against the liner.
• Make sure the liner is not pinching any wiring.
