🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to fully open the liftgate.
• Stand at the rear corner of the side you are replacing.
• The rear turn signal bulb is inside the outer tail lamp assembly mounted to the body.

Step 2: Remove the Tail Lamp Screws

• Use a Phillips #2 screwdriver to remove the visible tail lamp retaining screws along the liftgate opening.
• Place the screws somewhere safe so they do not roll away.
• Tip: A cup works great.

Step 3: Release the Tail Lamp Assembly

• Use a plastic trim removal tool at the inner edge of the tail lamp if it feels stuck.
• Pull the tail lamp straight rearward with both hands.
• The lamp has plastic guide pins. Pull straight back, not sideways.
• Tip: Wiggle gently, do not pry hard.

Step 4: Locate the Turn Signal Bulb Socket

• Look at the back of the tail lamp assembly.
• The turn signal bulb socket is the socket for the amber flashing lamp.
• A bulb socket is the plastic holder that locks the bulb into the lamp housing.

Step 5: Remove the Bulb Socket

• Use your hand to rotate the turn signal bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the tail lamp housing.
• No wrench is needed for this step.

Step 6: Remove the Old Bulb

• Use nitrile gloves or a clean microfiber cloth to grip the old bulb.
• Pull the bulb straight out of the socket if it is a wedge-style bulb.
• If your replacement bulb has side pins, push down slightly and twist counterclockwise to remove it.
• Do not crush the glass.

Step 7: Install the New Bulb

• Use nitrile gloves to handle the new rear turn signal bulb.
• Install the bulb into the socket the same way the old bulb came out.
• Make sure it seats fully and feels secure.
• If you touched the glass, wipe it clean with a clean microfiber cloth.

Step 8: Test the Turn Signal Before Reassembly

• Turn the ignition to ON without starting the engine.
• Use the turn signal stalk to switch on the side you repaired.
• Confirm the new bulb flashes normally.
• Turn the ignition OFF again before reinstalling the lamp.

Step 9: Reinstall the Bulb Socket

• Use your hand to insert the bulb socket into the tail lamp housing.
• Rotate the socket clockwise until it locks.
• It should stop firmly. Do not overtighten by hand.

Step 10: Reinstall the Tail Lamp Assembly

• Line up the plastic guide pins with the body openings.
• Use both hands to push the tail lamp straight forward until it seats flush.
• Use a Phillips #2 screwdriver to reinstall the retaining screws.
• Torque to snug only, approximately 2-3 Nm (18-27 in-lbs)
• Tip: Stop when the screw seats.

Step 11: Final Light Check

• Use the turn signal stalk to check the repaired side again.
• Use the hazard switch to confirm both rear turn signals flash.
• Close the liftgate by hand when finished.

• ✅ If the bulb still does not work, inspect the socket for corrosion or loose terminals.
