🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the tailgate and access the taillamp fasteners

• Open the tailgate fully.
• Use a 7mm socket and 1/4-inch ratchet to remove the two taillamp retaining bolts on the side you are servicing.
• Keep the bolts in a cup.

Step 2: Remove the taillamp housing

• Grip the taillamp assembly and pull it straight rearward to release the locator pins.
• If it feels stuck, use a trim panel tool to gently help it move free. Do not pry hard on the lens.

Step 3: Remove the bulb socket

• Locate the bulb socket on the back of the taillamp housing.
• Turn the socket counterclockwise by hand to unlock it, then pull it out.
• Twist, then pull.

Step 4: Replace the bulb

• Remove the old bulb from the socket.
• Install the new bulb in the socket.
• If the bulb has alignment pins, make sure it sits fully and straight.

Step 5: Reinstall the socket and lamp

• Insert the socket back into the taillamp housing.
• Turn it clockwise by hand until it locks.
• Set the taillamp housing back into place and make sure the locator pins line up.
• Install the two 7mm bolts and tighten them snugly. Torque to 3 Nm (27 in-lbs).

Step 6: Repeat on the other side

• Repeat the same process on the opposite taillamp.
• Replace both bulbs so both sides match in brightness and age.
