🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the liftgate and access the tail lamp fasteners

• Open the rear liftgate fully.
• Use a trim panel tool to remove any access cover or trim piece blocking the tail lamp fasteners.
• On each side, locate the retaining fasteners for the tail lamp assembly.

Step 2: Remove the tail lamp assembly

• Use an 8mm socket, 1/4-inch ratchet, and short extension to remove the tail lamp retaining bolts.
• Pull the tail lamp straight rearward to release the locating pins.
• If it sticks, wiggle gently. Do not pry hard against the painted body.
• Pull straight back to avoid breaking tabs.

Step 3: Remove the bulb socket

• Twist the bulb socket counterclockwise and pull it out of the lamp housing.
• If your lamp uses a connector, disconnect it by pressing the tab and pulling the connector body straight out.

Step 4: Replace the bulb

• Remove the old bulb from the socket by pulling it straight out.
• Install the new bulb by pressing it straight into the socket until fully seated.
• Replace the socket seal or foam gasket if it is torn, flattened, or missing.

Step 5: Reinstall the bulb socket and lamp

• Install the bulb socket into the lamp housing and twist it clockwise to lock it in place.
• Reconnect any electrical connector until it clicks.
• Align the tail lamp with the body openings and press it straight into place.
• Reinstall the retaining bolts using the 8mm socket.
• Torque to 4-6 Nm (35-53 in-lbs).

Step 6: Repeat on the other side

• Repeat the same steps for the opposite rear lamp.
• Replace both bulbs as a pair so the light output matches.
