🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk

• Use your hand to open the trunk fully.
• Use a flashlight to look at the left and right side trunk trim panels behind the tail light areas.
• Locate the carpeted trunk liner panels near the back corners.

Step 2: Remove the Trunk Trim Clips

• Use the trim clip removal tool to gently pry out the plastic trunk liner clips on one side.
• If a clip is tight, use the 1/4 inch flat-blade screwdriver to carefully lift the center of the clip first.
• Pull the carpeted trunk liner back just enough to reach the rear lamp bulb sockets.
• Work slowly to avoid breaking clips.

Step 3: Identify the Tail/Brake Light Socket

• Use the flashlight to locate the bulb socket in the back of the lamp assembly.
• The tail/brake light socket is usually the larger socket in the rear lamp area.
• Do not unplug or twist other sockets unless you are replacing those bulbs too.

Step 4: Remove the Bulb Socket

• Use your hand to grip the plastic bulb socket firmly.
• Twist the socket counterclockwise about 1/4 turn.
• Pull the socket straight out of the lamp housing.
• Use the shop towel if the socket is slippery.

Step 5: Remove the Old Bulb

• Use nitrile gloves to hold the socket.
• Pull the old bulb straight out of the socket unless the replacement bulb style requires a slight push-and-turn motion.
• Check the socket for melting, corrosion, or loose terminals.
• If the socket is melted or green with corrosion, the socket may also need replacement.

Step 6: Install the New Bulb

• Use nitrile gloves or a clean shop towel to handle the new rear tail/brake light bulb.
• Push the new bulb straight into the socket until fully seated.
• Make sure it sits squarely and does not wobble.
• Do not touch glass with bare fingers.

Step 7: Reinstall the Bulb Socket

• Use your hand to insert the socket back into the lamp housing.
• Line up the socket tabs with the matching slots in the lamp.
• Twist the socket clockwise about 1/4 turn until it locks.
• No torque spec applies; this is hand-tight only.

Step 8: Repeat on the Other Side

• Use the trim clip removal tool to release the opposite trunk liner clips.
• Use the flashlight to locate the opposite tail/brake light socket.
• Remove the socket by turning it counterclockwise by hand.
• Replace the bulb using nitrile gloves.
• Reinstall the socket by turning it clockwise until locked.

Step 9: Test Both Bulbs Before Reinstalling Trim

• Use your hand to turn the exterior lights on and confirm both tail lights illuminate.
• Press the brake pedal or have a helper press it to confirm both brake lights brighten.
• If one bulb does not work, turn the lights off, remove that bulb with nitrile gloves, rotate/reseat it, and test again.

Step 10: Reinstall the Trunk Liner

• Use your hands to move the carpeted trunk liner back into its original position.
• Push the plastic trim clips back into place by hand.
• If needed, use the flat-blade screwdriver 1/4 inch to gently guide the clip center flush.
• Make sure the liner is secure and not blocking the trunk hinge movement.
