⚠️ Safety & Precautions

• Turn the ignition off and make sure the exterior lights are switched off before starting.
• Let the bulbs cool completely if the lights were recently on. Halogen bulbs get very hot.
• Do not touch the glass part of a new bulb with your bare fingers. Skin oil can shorten bulb life.
• Battery disconnect is not required for this repair.
• Support the tail lamp housing carefully so the locating pins do not crack when removed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the cargo area access

• Open the rear liftgate.
• Move any cargo away from the tail lamp area.
• Use a trim panel tool if needed to gently move aside the small trim cover in the cargo area for access to the lamp fasteners.

Step 2: Remove the tail lamp fasteners

• Use a 10mm socket, 1/4-inch ratchet, and short extension to remove the tail lamp nuts.
• Keep the nuts in a safe place.
• Work slowly so the lamp does not bind.

Step 3: Remove the tail lamp assembly

• Pull the tail lamp straight rearward to release the locator pins.
• If it feels stuck, gently wiggle the housing by hand. Do not pry hard against the body panel.
• Once loose, disconnect the lamp enough to access the bulb socket.

Step 4: Remove the turn signal bulb socket

• Locate the rear turn signal bulb socket on the back of the lamp assembly.
• Twist the socket counterclockwise by hand and pull it out.
• If needed, use a clean glove for better grip.

Step 5: Replace the bulb

• Remove the old bulb from the socket.
• Install the new bulb firmly into the socket. The bulb should seat fully.
• Match the bulb base exactly.

Step 6: Reinstall the socket and lamp

• Insert the socket back into the lamp housing.
• Twist clockwise until it locks.
• Position the tail lamp assembly back into place, making sure the locator pins line up.
• Reinstall the 10mm nuts and tighten to 3 N·m (27 in-lbs).

Step 7: Test the repair

• Turn the ignition on.
• Activate the left and right turn signals one at a time.
• Make sure the new bulb flashes normally and the lens is seated correctly.
