🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release lever inside the cabin.
• Use your hand to release the hood safety latch at the front of the hood.
• Lift the hood and secure it with the hood prop rod if equipped.
• Use a small flashlight to look behind the front headlamp assembly.

Step 2: Find the Front Turn Signal Bulb Socket

• Use a small flashlight to identify the turn signal bulb socket at the rear of the headlamp assembly.
• The front turn signal bulb socket is separate from the headlight bulb socket and twists into the lamp housing.
• Look for the socket leading to the amber turn signal section of the headlamp.
• Work slowly; space is tight.

Step 3: Remove the Bulb Socket

• Use your gloved hand to grip the turn signal bulb socket firmly.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the headlamp housing.
• No bolts are used here, so there is no torque specification for removal.

Step 4: Remove the Old Bulb

• Use your gloved hand to press the old bulb slightly into the socket.
• Turn the bulb counterclockwise to unlock it.
• Pull the bulb straight out of the socket.
• If the bulb is broken, use safety glasses and remove glass pieces carefully with a clean microfiber towel.

Step 5: Install the New Bulb

• Use nitrile gloves to handle the new 2357A amber front turn signal bulb.
• Line up the small locking pins on the bulb with the slots in the socket.
• Push the bulb gently into the socket.
• Turn the bulb clockwise until it locks in place.
• If you touch the glass by mistake, use a clean microfiber towel to wipe it before installation.

Step 6: Reinstall the Bulb Socket

• Use your gloved hand to insert the bulb socket back into the headlamp housing.
• Line up the tabs on the socket with the openings in the housing.
• Turn the socket clockwise about a quarter turn until it locks.
• Do not overtighten it. It only needs to be snug by hand.
• No torque specification applies because this socket is hand-tightened only.

Step 7: Test the Turn Signal

• Use your hand to turn the ignition to accessory or start the vehicle.
• Switch on the left or right turn signal for the side you repaired.
• Walk to the front and confirm the new bulb flashes normally.
• Turn on the hazard lights and confirm both front signals flash.
• If the signal flashes very fast, the bulb may not be seated correctly or the wrong bulb may be installed.

Step 8: Close the Hood

• Use your hand to lower the hood carefully.
• Make sure no tools or towels are left in the engine bay.
• Close the hood firmly and confirm it latches.
