🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the left rear lamp assembly

• Open the liftgate and locate the rear lamp screws on the inside edge of the left lamp.
• Use a Phillips #2 screwdriver to remove the screws.
• Carefully pull the lamp straight rearward to release the locating pins.
• If it feels stuck, use a plastic trim removal tool to gently help it break free. Pull straight back, not sideways.

Step 2: Remove the taillight bulb socket

• Find the socket that corresponds to the taillight bulb (typically a larger socket for a 3157 style bulb).
• Twist the socket counterclockwise about 1/4 turn by hand and pull it out.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new 3157 bulb by pushing it straight in until fully seated.
• Reinstall the socket into the lamp and twist clockwise to lock.

Step 4: Reinstall the left lamp assembly

• Line up the locating pins with their holes and press the lamp straight in until it sits flush.
• Reinstall the screws using a Phillips #2 screwdriver.
• Torque to 2 Nm (18 in-lbs) (snug only—do not overtighten).

Step 5: Repeat on the right side

• Repeat Steps 1-4 for the right rear lamp using the same Phillips #2 screwdriver and plastic trim removal tool.
• Replace the second 3157 bulb so both sides match brightness and color.
