🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Make Space in the Wheel Well

• Put on safety glasses and nitrile gloves.
• Turn the steering wheel fully away from the side you are working on.
• For the left bulb, turn the wheel to the right. For the right bulb, turn the wheel to the left.
• If you need more space, use the floor jack to raise the front corner.
• Support the vehicle with jack stands before reaching into the wheel-well area.
• Turning the wheel often gives enough room.

Step 2: Open the Front Fender Liner

• Use the flat trim clip removal tool to remove the plastic push clips at the front of the inner fender liner.
• Use the 8mm socket and 1/4-inch ratchet to remove the small screws holding the liner near the front bumper edge.
• Pull the liner back gently by hand to expose the rear of the headlamp housing.
• If a clip breaks, replace it with a new fender liner push clip.

Step 3: Find the Turn Signal Bulb Socket

• Reach behind the headlamp housing through the wheel-well opening.
• Locate the smaller twist-lock bulb socket for the front turn signal.
• The socket will sit in the headlamp housing and have wires attached to it.
• Use a clean microfiber towel if the area is dirty before opening the socket.

Step 4: Remove the Bulb Socket

• Grip the turn signal bulb socket by hand.
• Turn the socket counterclockwise about one quarter turn.
• Pull the socket straight out of the headlamp housing.
• If it is tight, use needle-nose pliers gently on the socket body only.
• Do not pull on the wires.

Step 5: Remove the Old Bulb

• Hold the socket firmly in one hand.
• Pull the old bulb straight out of the socket by hand.
• If the bulb is stuck, use a clean microfiber towel for grip.
• Check the socket for melting, green corrosion, or loose terminals.
• If the socket is burned or corroded, the socket should be replaced before installing the bulb.

Step 6: Install the New Bulb

• Push the new front amber turn signal bulb straight into the socket until fully seated.
• Do not force the bulb. It should slide in smoothly.
• Keep fingers off the glass when possible by wearing nitrile gloves.
• If you touch the glass, wipe it gently with a clean microfiber towel.

Step 7: Test Before Reassembly

• Keep the bulb and socket away from moving parts.
• Turn the ignition to RUN.
• Switch on the turn signal for the side you are repairing.
• Confirm the new bulb flashes normally.
• Turn the ignition off and turn the lights off before continuing.
• If it does not light, remove the bulb by hand, rotate it 180 degrees, reinstall it, and test again.

Step 8: Reinstall the Bulb Socket

• Line up the tabs on the socket with the slots in the headlamp housing.
• Push the socket straight into the housing.
• Turn the socket clockwise about one quarter turn until it locks.
• Make sure it sits flat so water cannot enter the headlamp.

Step 9: Reinstall the Fender Liner

• Move the fender liner back into place by hand.
• Use the 8mm socket and 1/4-inch ratchet to reinstall the screws.
• Torque small fender liner screws snug only, about 2-3 Nm (18-27 in-lbs).
• Push the plastic clips back in by hand until flush.

Step 10: Repeat on the Other Side

• Turn the steering wheel the opposite direction to create access.
• Repeat Steps 2-9 for the other front turn signal bulb.
• Replace both bulbs as a pair for even age and brightness.

✅ After Repair

• Turn on the left turn signal and confirm the front, rear, and dash indicator flash normally.
• Turn on the right turn signal and confirm the front, rear, and dash indicator flash normally.
• Press the hazard switch and confirm both front turn signals flash.
• If the signal flashes very fast, one bulb is not working or the wrong bulb type is installed.
• If Tire/Jack Mode was turned on, turn it off using Controls > Suspension > Tire/Jack Mode.
