🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp fasteners

• Open the liftgate.
• Locate the two mounting screws on the inside edge of the rear tail lamp (near the liftgate opening).
• Use a flashlight if the area is dark.

Step 2: Remove the tail lamp screws

• Use a Phillips #2 screwdriver to remove the two screws.
• Set the screws somewhere safe so they don’t fall into the body.
• On reassembly: Torque to 3 Nm (27 in-lbs).

Step 3: Release the tail lamp from the body clips

• Grip the lamp housing with both hands and pull it straight rearward (toward you).
• If it feels stuck, use a plastic trim removal tool to gently help start the separation at the edge.
• Pull straight back—don’t pry hard.

Step 4: Remove the turn signal bulb socket

• Find the turn signal socket on the back of the lamp (typically the amber/clear section).
• Twist the socket counterclockwise about 1/4 turn to unlock it.
• Pull the socket straight out.

Step 5: Replace the bulb

• Wear nitrile gloves so you don’t touch the bulb glass.
• Pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb (1156 / BA15s) straight in until fully seated.
• If the bulb is tight, use a small pick tool carefully to help wiggle it free (do not damage the socket).

Step 6: Reinstall the socket and test

• Insert the socket back into the lamp and twist clockwise to lock.
• Turn the ignition to ON (engine off is fine) and switch the turn signal on.
• Verify normal blinking speed on the dash and that the rear turn signal is bright and steady.

Step 7: Reinstall the tail lamp assembly

• Line up the lamp’s locating pins/clips with the body holes.
• Press the lamp straight forward until it seats flush.
• Reinstall the two screws with a Phillips #2 screwdriver and Torque to 3 Nm (27 in-lbs).

✅ After Repair
