🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the access panels in the cargo area

• Put on nitrile gloves and safety glasses.
• On the side you’re working on, use a trim panel removal tool (a plastic pry tool that pops clips without scratching) to open/remove the small interior access cover behind the tail lamp area.

Step 2: Remove the tail lamp retaining nuts

• Use a 10mm socket, 1/4" drive ratchet, and 6" socket extension to remove the two 10mm nuts holding the tail lamp.
• Set the nuts aside where they won’t roll away.

Step 3: Pull the tail lamp assembly off the body

• Grab the tail lamp with both hands and pull it straight rearward.
• If it’s stuck on the alignment pins, gently wiggle while pulling—do not pry on the painted body.
• Pull straight back to avoid breaking pins.

Step 4: Remove the rear turn signal bulb socket

• Find the turn signal socket on the back of the lamp assembly (it’s the socket for the amber bulb).
• Twist the socket counterclockwise by hand to unlock it, then pull it out.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket. If it’s tight, use needle-nose pliers gently.
• Install the new 7440A amber bulb by pushing it straight in until fully seated.
• Reinstall the socket into the lamp and twist clockwise to lock.

Step 6: Reinstall the tail lamp assembly

• Line up the lamp’s guide pins with the body holes, then push the lamp straight in until it seats flush.
• Install the two nuts using the 10mm socket, ratchet, and extension.
• Torque to 5 N·m (4 ft-lbs).
• Snap the interior access cover back into place using the trim panel removal tool to align clips if needed.

Step 7: Repeat on the other side

• Do the same steps for the other rear turn signal so brightness and color match.

✅ After Repair
