🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate and Locate the Lamp Screws

• Use your hands to open the liftgate fully.
• Stand at the rear corner of the vehicle and look along the inner edge of the tail light assembly.
• You will see the tail light mounting screws exposed with the liftgate open.
• Work on one side first.

Step 2: Remove the Tail Light Mounting Screws

• Use the T30 Torx screwdriver to remove the tail light mounting screws.
• Place the screws somewhere safe so they do not roll away.
• Support the lamp with one hand while removing the last screw.

Step 3: Release the Tail Light Assembly

• Use both hands to pull the tail light assembly straight rearward from the body.
• If it feels stuck, use the plastic trim removal tool gently at the outer edge to help release the retaining pins.
• Do not twist the lamp hard; the locating pins can crack.
• Pull straight back, not sideways.

Step 4: Remove the Bulb Socket

• Look at the back of the tail light assembly and find the tail/stop bulb socket.
• Use your hand to rotate the bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.
• If needed, use the clean nitrile gloves to grip the socket securely.

Step 5: Replace the Bulb

• Use your gloved hand to pull the old bulb straight out of the socket.
• Use the microfiber cloth to hold the new bulb if you are not wearing gloves.
• Push the new rear tail/stop light bulb straight into the socket until fully seated.
• Do not force it at an angle.

Step 6: Reinstall the Bulb Socket

• Insert the bulb socket back into the tail light housing.
• Use your hand to rotate the socket clockwise until it locks.
• Make sure the socket is seated evenly to help keep water out of the lamp.

Step 7: Test the New Bulb Before Reinstalling the Lamp

• With the lamp still supported, turn the headlamp switch to Parking Lamps.
• Press the brake pedal or have a helper press it.
• Confirm the new bulb works for tail light and brake light functions.
• Turn the headlamp switch back to Off before continuing.

Step 8: Reinstall the Tail Light Assembly

• Align the tail light guide pins with the body openings.
• Use both hands to press the lamp straight forward into place.
• Make sure the lamp sits flush with the body panel.
• Use the T30 Torx screwdriver to reinstall the mounting screws.
• Tighten the screws snugly by hand; do not overtighten plastic lamp mounts.

Step 9: Repeat on the Other Side

• Use the T30 Torx screwdriver to remove the screws on the opposite tail light.
• Use the plastic trim removal tool if the lamp needs gentle help releasing.
• Replace the second rear tail/stop light bulb the same way.
• Reinstall the second lamp and tighten the screws snugly by hand.
