🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to open the liftgate fully so you can reach the inner edge of each rear combination lamp.
• Use the flashlight to look at the inner side of the taillight housing near the liftgate opening.

Step 2: Remove the Left Rear Lamp Cover or Fastener Access

• Use the plastic trim removal tool to gently remove the small trim cover hiding the rear lamp fasteners, if equipped.
• Set the cover aside where it will not be stepped on.
• Plastic tabs break if rushed.

Step 3: Remove the Left Rear Lamp Fasteners

• Use the 10mm socket and 3/8-inch ratchet to remove the exposed rear combination lamp retaining bolts.
• Support the lamp with one hand while removing the last bolt.
• Keep the bolts in a safe place.

Step 4: Pull the Left Rear Lamp Straight Back

• Use both hands to pull the lamp assembly straight rearward from the body.
• Do not pry against the painted body panel.
• If it feels stuck, gently wiggle the lamp while pulling straight back.
• Do not yank the lamp because the wiring is still attached.

Step 5: Remove the Left Rear Turn Signal Socket

• Use the flashlight to identify the rear turn signal bulb socket on the back of the lamp housing.
• Use your gloved hand to turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the lamp housing.

Step 6: Replace the Left Rear Turn Signal Bulb

• Use your gloved hand to pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb straight into the socket until fully seated.

Step 7: Reinstall the Left Rear Turn Signal Socket

• Use the flashlight to align the socket tabs with the slots in the lamp housing.
• Push the socket into the lamp housing.
• Turn the socket clockwise until it locks.

Step 8: Reinstall the Left Rear Lamp Assembly

• Use both hands to align the lamp guide pins with the body openings.
• Push the lamp straight forward until it seats flush with the body.
• Use the 10mm socket and 3/8-inch ratchet to reinstall the retaining bolts.
• Torque to 5.4 Nm (48 in-lbs).
• Use your hand to reinstall the trim cover, if removed.

Step 9: Replace the Right Rear Turn Signal Bulb

• Repeat Steps 2 through 8 on the right rear lamp assembly.
• Use the plastic trim removal tool for the cover, if equipped.
• Use the 10mm socket and 3/8-inch ratchet for the lamp fasteners.
• Use the flashlight to identify the turn signal socket before twisting it out.
• Torque to 5.4 Nm (48 in-lbs) when reinstalling the lamp fasteners.

Step 10: Test the Rear Turn Signals

• Turn the ignition to ON without starting the engine.
• Use the turn signal stalk to test the left rear turn signal.
• Use the turn signal stalk to test the right rear turn signal.
• Press the hazard switch and confirm both rear turn signal bulbs flash evenly.
