📋 Before You Begin
- Park on level ground, shift to 1st gear, and set the parking brake.
- Open the hood and set a flashlight so you can see behind the headlight.
- If access is tight, plan to remove the air intake duct (right side) or washer filler neck (left side).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Identify the correct bulb socket
- Use a flashlight and look behind the headlight on the side you’re replacing.
- Find the turn signal socket (it’s the socket that twists out; it typically points toward the fender side of the headlight).
- If unsure, turn hazards on briefly. Turn them back OFF before touching anything.
Step 2: Create working room (only if needed)
- If your hand doesn’t fit comfortably, remove nearby covers/ducting.
- On the air intake duct area: use a trim clip removal tool or small flat-blade screwdriver to lift the center pin of the plastic clips, then pull the clips out.
- If a 10mm bolt is present: use a 10mm socket with a 1/4" ratchet and 6" extension to remove it.
- Move the duct/cover aside gently (no need to force it).
Step 3: Remove the turn signal bulb socket
- Wear nitrile gloves and safety glasses.
- Grip the turn signal socket firmly and twist it counterclockwise about 1/4 turn, then pull it straight out by hand.
Step 4: Replace the bulb
- Pull the old bulb straight out of the socket by hand.
- Install the new front turn signal bulb (amber) by pushing it straight into the socket until fully seated.
- Hold the bulb by the base only.
Step 5: Reinstall the socket
- Insert the socket back into the headlight housing, making sure the tabs align.
- Twist clockwise about 1/4 turn by hand until it stops (snug, not forced).
Step 6: Reinstall anything you removed
- Reposition the duct/cover.
- Reinstall any bolts using a 10mm socket with a 1/4" ratchet and 6" extension (snug by feel; these are small fasteners).
- Reinstall push clips: press the outer body in first, then press the center pin flush using your thumb or a small flat-blade screwdriver.
✅ After Repair
- Turn ignition ON and test the left/right turn signals and hazards.
- Verify the bulb blinks at a normal speed (fast blinking usually means a bulb isn’t working or isn’t seated).
- Make sure any ducts/covers you moved are secure and not rubbing a belt or fan area.
