🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Liftgate

• Use your hand to open the rear liftgate fully.
• Stand on the side with the failed rear turn signal.
• Use safety glasses to protect your eyes from dust or loose trim debris.

Step 2: Remove the Tail Lamp Access Cover

• Look at the inner side of the tail lamp area, just inside the liftgate opening.
• Use a flat trim removal tool to gently pry off the small access cover.
• A trim removal tool is a plastic pry tool that helps remove panels without scratching paint or trim.
• Work slowly to avoid broken clips.

Step 3: Locate the Rear Turn Signal Bulb Socket

• Use your hand to feel for the bulb socket behind the tail lamp.
• The rear turn signal bulb socket is usually the amber signal bulb position in the outer tail lamp assembly.
• If needed, use a shop towel to improve grip on the socket.

Step 4: Remove the Bulb Socket

• Use your hand to rotate the bulb socket counterclockwise about a quarter turn.
• Pull the socket straight out of the tail lamp housing.
• No torque spec applies because the socket is hand-tight only.

Step 5: Remove the Old Bulb

• Use clean nitrile gloves to grip the old bulb.
• Pull the bulb straight out of the socket.
• If the bulb is stuck, use a shop towel for grip and gently wiggle it side to side while pulling.
• Do not crush the glass bulb.

Step 6: Install the New Bulb

• Use clean nitrile gloves to handle the new rear turn signal bulb.
• Push the new bulb straight into the socket until it seats fully.
• Make sure it is snug and not loose in the socket.
• Do not touch the bulb glass.

Step 7: Reinstall the Bulb Socket

• Insert the bulb socket back into the tail lamp housing.
• Use your hand to rotate the socket clockwise until it locks.
• No torque spec applies because this is a plastic twist-lock socket; tighten by hand only.

Step 8: Test the Turn Signal

• Use your hand to press the unlock button or enter the vehicle carefully.
• Turn the ignition to RUN without starting the engine.
• Move the turn signal stalk to test the repaired side.
• Check that the rear turn signal flashes normally and is not blinking fast.
• You can also press the hazard switch to test both rear signals together.

Step 9: Reinstall the Access Cover

• Turn the ignition OFF.
• Use your hand to align the access cover with the opening.
• Press the cover into place until it snaps in securely.
• Use a shop towel to wipe fingerprints from the lamp lens.
