Step 1: Open the rear access area

• Open the rear hatch and locate the inside access panels behind the taillights.
• Use a trim panel removal tool to gently pop off the small access cover on the side you are servicing.
• Set the cover aside so the clips do not get lost.

Step 2: Remove the bulb socket

• Reach into the opening and find the rear turn signal bulb socket.
• Use your hand to twist the socket counterclockwise and pull it straight out.
• Do not force it.

Step 3: Replace the bulb

• Use a flat-blade screwdriver if needed to gently release the bulb from the socket, but only if the bulb is tight.
• Remove the old bulb by pulling it straight out.
• Install the new bulb by pushing it firmly into the socket until fully seated.

Step 4: Reinstall the socket

• Align the socket tabs with the housing.
• Use your hand to twist the socket clockwise until it locks.
• Make sure it sits flush and does not wobble.

Step 5: Test the new bulb

• Turn on the ignition.
• Activate the left and right turn signals one at a time.
• Confirm the new bulb flashes normally.

Step 6: Reinstall the access cover

• Put the trim cover back in place.
