🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Trunk

• Use your hand to open the trunk fully.
• Use a work light to illuminate the inside corner of the trunk behind the tail lamp you are repairing.

Step 2: Move the Trunk Side Liner Aside

• Use the flat-blade trim clip remover to carefully lift out the plastic trunk liner clips near the tail lamp area.
• Pull the trunk side liner inward by hand just enough to access the rear of the tail lamp assembly.
• Do not crease the liner sharply.
• Only move what you need.

Step 3: Locate the Rear Turn Signal Bulb Socket

• Use the work light to look at the back side of the tail lamp assembly.
• The rear turn signal bulb socket is the socket for the amber turn signal bulb in the tail lamp assembly.
• Follow the wiring to the socket and confirm it is seated in the lamp housing.

Step 4: Remove the Bulb Socket

• Use your hand to grip the rear turn signal bulb socket.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the tail lamp housing.
• Do not use pliers on the socket because it can crack.

Step 5: Remove the Old Bulb

• Use nitrile gloves to grip the old bulb.
• Pull the bulb straight out of the socket.
• If the bulb is tight, gently wiggle it while pulling straight outward.
• Inspect the socket for corrosion, heat damage, or melted plastic.

Step 6: Install the New Bulb

• Use nitrile gloves to handle the new rear turn signal bulb.
• Push the new bulb straight into the socket until fully seated.
• Make sure the bulb does not feel loose in the socket.
• Keep fingers off the glass.

Step 7: Test the Bulb Before Reassembly

• Use your hand to operate the turn signal stalk for the side you replaced.
• Check that the new rear turn signal flashes at a normal speed.
• Turn the signal OFF before reinstalling the socket.
• If the bulb does not light, remove it by hand, reseat it fully, and test again.

Step 8: Reinstall the Bulb Socket

• Use your hand to align the socket tabs with the openings in the tail lamp housing.
• Push the socket straight into the housing.
• Turn the socket clockwise about a quarter turn until it locks.
• The socket should sit flush and feel secure.

Step 9: Reinstall the Trunk Liner

• Use your hand to move the trunk side liner back into its original position.
• Use your hand to push the plastic clips back into place until fully seated.
• If any lamp retaining nuts were loosened for access, use a 10mm socket, 1/4-inch drive ratchet, and 1/4-inch drive 6-inch extension to snug them evenly.
• Torque to 5 Nm (44 in-lbs) if a tail lamp retaining nut was removed or loosened.

Step 10: Repeat on the Other Side if Replacing in Pairs

• Use the same tools and steps on the opposite rear turn signal bulb.
• Replacing both rear turn signal bulbs together helps keep brightness and color even.
