⚠️ Safety & Precautions

• Turn the lights off and remove the key/fob from the vehicle.
• Let the bulb cool before touching it. Halogen bulbs get very hot.
• Do not touch a new halogen bulb with bare fingers. Skin oil shortens bulb life.
• Work carefully around the tail lamp lens and plastic clips. They can crack easily.
• Battery disconnect is not required for this repair.

📋 Before You Begin

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the rear access area

• Open the liftgate and move any cargo out of the way.
• Use your hand or a trim panel tool to gently remove the small side access cover in the cargo area near the tail lamp.
• Work slowly to avoid breaking clips.

Step 2: Remove the bulb socket

• Reach behind the tail lamp and find the rear turn signal bulb socket.
• Use your hand to twist the socket counterclockwise, then pull it straight out.
• If it is tight, use a small flathead screwdriver carefully to help release it.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new rear turn signal bulb by pushing it straight in until fully seated.
• Do not force it. The bulb should fit cleanly.

Step 4: Reinstall the socket

• Line the socket tabs up with the housing opening.
• Use your hand to twist the socket clockwise until it locks.
• Make sure it sits snug and does not wobble.

Step 5: Test the new bulb

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

✅ After Repair

• Check the turn signal from outside the vehicle to confirm proper operation.
• Make sure the tail lamp area is sealed and the access cover is back in place.
• If the signal still flashes fast, the bulb may not be fully seated or the wrong type may be installed.
