🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear tail lamp fasteners

• Open the liftgate.
• Locate the fasteners on the inboard edge of the outer tail lamp (the part mounted to the body, not the liftgate).
• Some Muranos use Phillips screws here; others use 10mm nuts/bolts. Use a flashlight to confirm which you have.

Step 2: Remove the tail lamp fasteners

• If equipped with screws: remove them using a Phillips #2 screwdriver.
• If equipped with nuts/bolts: remove them using a 10mm socket and 1/4" ratchet.
• Set the fasteners aside where they won’t roll away.

Step 3: Pop the tail lamp loose from the body clips

• Hold the lamp with one hand.
• Use a plastic trim tool set to gently work at the seam and pull the lamp straight rearward (away from the vehicle).
• Pull straight back to avoid breaking pins.

Step 4: Remove the rear turn signal bulb socket

• Find the turn signal bulb socket on the back of the lamp (it will twist-lock into the housing).
• Twist the socket counterclockwise by hand and pull it out.

Step 5: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb (amber, 7440A) straight into the socket until fully seated.

Step 6: Test the turn signal before reassembly

• Reinstall the bulb socket into the lamp and twist clockwise to lock it.
• Turn the ignition to ON and activate the turn signal.
• Confirm it flashes normally (not rapidly).

Step 7: Reinstall the tail lamp

• Align the lamp locating pins with the body holes and press the lamp straight forward until it seats flush.
• Reinstall the screws/nuts using a Phillips #2 screwdriver or 10mm socket.
• Torque to 5 Nm (44 in-lbs) using a torque wrench (in-lb) (specialty).

✅ After Repair

• Verify both rear turn signals work (left and right), plus hazards.
• Check that the tail lamp sits evenly and doesn’t wiggle.
• If you got rapid flashing, the bulb may be the wrong type, not fully seated, or there may be a socket/ground issue.
