🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Wheelhouse Access Area

• Put on the safety glasses and clean nitrile gloves.
• Use the flashlight rated 200 lumens minimum to locate the push-pin retainers along the forward edge of the front wheelhouse liner.
• Use the 1/4-inch flat-blade screwdriver to lift each retainer’s center pin slightly.
• Use the plastic push-pin trim removal tool to remove the loosened retainers without tearing the liner.
• Pull the front section of the liner gently rearward to create access behind the headlamp.
• Keep each retainer together for easy reassembly.

Step 2: Remove the Turn-Signal Socket

• Use the flashlight rated 200 lumens minimum to identify the turn-signal socket at the rear of the headlamp assembly.
• With your gloved hand, rotate the socket counterclockwise approximately one-quarter turn.
• Pull the socket straight out without pulling on its wires.

Step 3: Replace the Bulb

• Using clean nitrile gloves, pull the old bulb straight out of the socket; do not twist it.
• Inspect the socket for melted plastic, green corrosion, or burned terminals. Replace or repair the socket before continuing if damage is present.
• Use clean nitrile gloves to press the new 7444NA amber bulb straight into the socket until fully seated.
• Never force a bulb that is not aligned.

Step 4: Test the New Bulb

• Keep the socket outside the lamp and clear of moving parts.
• Switch on the ignition and operate the turn signal for that side.
• Confirm that the new bulb flashes normally, then switch the ignition and exterior lights off.
• If it flashes rapidly, reseat the bulb and inspect the socket terminals using the flashlight rated 200 lumens minimum.

Step 5: Reinstall the Socket

• With your gloved hand, align the socket tabs with the openings in the headlamp assembly.
• Insert the socket fully and rotate it clockwise approximately one-quarter turn until locked.
• Verify that the socket seal sits evenly and the wiring is not pinched.
• No torque specification applies because the socket uses a hand-turned locking connection.

Step 6: Reinstall the Wheelhouse Liner

• Move the liner back into its original position by hand and align all mounting holes.
• Reset each push-pin retainer by extending its center pin.
• Insert the retainer bodies through the aligned holes, then press their center pins flush by hand.
• Use the plastic push-pin trim removal tool to check that every retainer is fully seated and the liner cannot rub against the tire.
• Replace any cracked or loose retainers.

Step 7: Replace the Opposite Bulb

• Turn the steering wheel fully in the opposite direction.
• Repeat Steps 1-6 with the same listed tools on the other side.
• Replacing both bulbs together helps maintain equal brightness and reliability.

✅ After Repair

• ✅ Test the left turn signal, right turn signal, and hazard-warning lights.
• 👀 Walk around the front of your Tahoe and confirm both lamps are equally bright and flashing at a normal speed.
• 🛞 Turn the steering wheel fully left and right, confirming that neither wheelhouse liner contacts a tire.
• 💧 After rain or washing, inspect the headlamps for unusual moisture that could indicate an incorrectly seated socket seal.
