🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release inside the cabin, then release the secondary latch at the front of the hood.
• Raise the hood and secure it with the hood prop rod.
• Use a flashlight to inspect the rear of the headlamp on the side you are replacing.

Step 2: Find the Front Turn Signal Socket

• Use the flashlight to locate the turn signal bulb socket at the rear/outboard area of the headlamp assembly.
• The front turn signal socket is usually a larger twist-lock socket with wires going into it.
• Compare with the other side if unsure.

Step 3: Remove the Bulb Socket

• Put on nitrile gloves.
• Grip the turn signal bulb socket by hand.
• Turn the socket counterclockwise about a quarter turn, then pull it straight out of the headlamp housing.
• No torque spec applies; this is a hand-tight twist-lock socket.

Step 4: Remove the Old Bulb

• Hold the socket firmly with one hand while wearing nitrile gloves.
• Pull the old bulb straight out of the socket by hand.
• If the bulb is stuck, use a clean microfiber towel for extra grip and gently rock it side to side while pulling.
• Do not squeeze hard enough to break the glass.

Step 5: Install the New Bulb

• Use nitrile gloves or a clean microfiber towel to handle the new amber front turn signal bulb.
• Push the new bulb straight into the socket until it seats fully.
• Make sure the bulb is secure and not loose in the socket.
• Do not twist the glass bulb.

Step 6: Reinstall the Socket

• Use the flashlight to line up the tabs on the bulb socket with the slots in the headlamp housing.
• Insert the socket straight into the headlamp.
• Turn the socket clockwise by hand until it locks in place.
• No torque spec applies; tighten only until the socket stops.

Step 7: Test the Turn Signal

• Turn the ignition to ON without starting the engine.
• Switch on the left or right turn signal for the side you replaced.
• Walk to the front and confirm the new bulb flashes bright amber.
• Turn on the hazard lights and confirm both front turn signals flash normally.

Step 8: Close the Hood

• Use your hand to lower the hood slightly while removing the prop rod.
• Secure the prop rod in its clip.
• Lower the hood and let it latch firmly.
• Pull up gently on the hood to confirm it is fully latched.

✅ After Repair

• ✅ Confirm the turn signal indicator on the dash blinks at a normal speed.
• ✅ If the dash indicator still blinks very fast, recheck that the bulb is fully seated or replace the bulb on the other side.
• ✅ Check the rear turn signal too, because a failed rear bulb can also cause fast blinking.
• ✅ No scan tool, programming, or reset is required for this repair.
