🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood and Locate the Turn Signal Socket

• Use the hood release inside the cabin, then lift the hood from the front latch.
• Use a flashlight to look behind the headlamp assembly on the side you are replacing.
• The front turn signal bulb socket is at the rear of the headlamp housing, separate from the main headlight bulb area.
• Work on one side at a time.

Step 2: Move the Air Intake Duct if More Space Is Needed

• On the passenger side, use a flat-blade screwdriver or trim clip removal tool to release any plastic retainers holding the air intake duct if it blocks access.
• Lift the duct out gently and set it aside.
• Do not pull hard on nearby wiring or hoses.

Step 3: Remove the Turn Signal Bulb Socket

• Use your gloved hand to grip the turn signal bulb socket at the back of the headlamp.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight rearward out of the headlamp housing.
• If it is tight, use a flashlight to confirm you are turning the correct socket before applying more pressure.

Step 4: Remove the Old Bulb

• Use nitrile gloves to hold the socket steady.
• Pull the old bulb straight out of the socket.
• If the bulb is stuck, gently wiggle it while pulling straight outward.
• Check the socket for melting, corrosion, or a loose terminal.

Step 5: Install the New Bulb

• Use nitrile gloves to handle the new front turn signal bulb.
• Push the new bulb straight into the socket until it seats fully.
• Do not touch the glass with bare fingers.
• A fully seated bulb will not wobble.

Step 6: Reinstall the Bulb Socket

• Use your gloved hand to insert the socket into the headlamp housing.
• Align the socket tabs with the slots in the housing.
• Turn the socket clockwise about a quarter turn until it locks.
• No torque spec applies because this socket is hand-tight only.

Step 7: Reinstall Any Removed Intake Ducting

• Use your hands to place the air intake duct back into position if it was removed.
• Use the trim clip removal tool or flat-blade screwdriver to reinstall the plastic retainers.
• Make sure the duct sits flat and does not rub the fan, belt area, or wiring.

Step 8: Test the Turn Signal

• Turn the ignition to Run without starting the engine.
• Switch on the turn signal for the side you repaired.
• Use a flashlight to confirm the new bulb flashes normally.
• Turn on the hazard lights and check both front turn signals.
