🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear tail lamp fasteners

• Open the liftgate.
• Use a Phillips #2 screwdriver to remove the two screws along the inside edge of the tail lamp (the edge closest to the liftgate opening).
• Set the screws somewhere safe so they don’t fall into the bumper area.

Step 2: Pull the tail lamp assembly straight out

• Grip the tail lamp with both hands and pull it straight rearward (toward you).
• If it feels stuck, use a plastic trim removal tool to gently help it start moving. (A trim tool is a plastic pry tool that helps release clips without scratching paint.)
• Tip: Don’t pry on the painted body edge.

Step 3: Remove the turn signal bulb socket

• Look behind the lamp and find the turn signal socket (usually the larger dual-filament bulb socket in the lamp).
• Use your flashlight to see the socket tabs clearly.
• Twist the socket counterclockwise about 1/4 turn by hand, then pull the socket out of the tail lamp.

Step 4: Replace the bulb

• Put on nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new 3157 type bulb straight into the socket until fully seated.
• Tip: If the bulb is glass, don’t touch it bare-handed.

Step 5: Reinstall the socket and tail lamp

• Insert the socket back into the tail lamp and twist clockwise to lock.
• Line up the tail lamp’s locating pins with the body holes, then push the lamp straight in until it sits flush.
• Reinstall the two screws using the Phillips #2 screwdriver and snug them evenly.
• Torque to 2 Nm (18 in-lbs) (snug, not tight).

✅ After Repair

• Turn the ignition to ON and test the turn signals and hazards on both sides.
• Confirm the lamp sits flush and doesn’t wiggle (loose lamp = water leak risk).
• If the new bulb still doesn’t work, re-check that the socket is fully locked and the bulb is fully seated.
