🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to fully open the liftgate.
• Make sure the liftgate is stable before working near the rear lamps.
• Use safety glasses to protect your eyes from dust or clips.

Step 2: Remove the Rear Lamp Access Cover

• Look at the inside edge of the taillight area near the liftgate opening.
• Use the trim panel removal tool or small flathead screwdriver to gently pry off the small access cover.
• If screws are present, use a Phillips screwdriver to remove them.
• Go slow to avoid cracked plastic.

Step 3: Remove the Bulb Socket

• Find the taillight bulb socket behind the access opening.
• Use your gloved hand to grip the socket body.
• Turn the socket counterclockwise about one-quarter turn.
• Pull the socket straight out of the lamp housing.
• A bulb socket is the plastic holder that locks the bulb into the taillight housing.

Step 4: Remove the Old Bulb

• Use nitrile gloves to hold the old bulb.
• Pull the bulb straight out of the socket if it is a push-in style.
• If the bulb uses a twist-lock base, press in slightly and turn counterclockwise, then remove it.
• Use a clean microfiber towel if the bulb is difficult to grip.

Step 5: Install the New Bulb

• Use nitrile gloves to handle the new bulb.
• Push the new bulb firmly into the socket until fully seated.
• If it is a twist-lock bulb, align the pins, press in gently, and turn clockwise until it locks.
• Do not force the bulb. If it does not fit, remove it and realign it.
• Never touch glass with bare fingers.

Step 6: Reinstall the Bulb Socket

• Use your gloved hand to insert the socket back into the taillight housing.
• Align the socket tabs with the housing slots.
• Turn the socket clockwise until it locks in place.
• No torque spec applies; hand-tight only.

Step 7: Test the First Taillight

• Turn the headlamp switch to the parking light position.
• Check that the replaced taillight bulb illuminates.
• Turn the lights back off before continuing.
• If the bulb does not light, use the nitrile gloves to remove it and reinstall it fully.

Step 8: Repeat on the Other Side

• Move to the opposite rear lamp.
• Use the trim panel removal tool or small flathead screwdriver to remove the access cover.
• Use the Phillips screwdriver if screws are present.
• Remove the socket, replace the bulb, and reinstall the socket using the same steps.

Step 9: Reinstall Covers and Fasteners

• Use your hand to snap the access covers back into place.
• If screws were removed, use the Phillips screwdriver to reinstall them snugly.
• No torque spec applies; tighten gently by hand.
• Plastic strips easily, so do not overtighten.
