🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the liftgate and find the left lamp retainers

• Use the flashlight to look along the inner edge of the left rear lamp housing.
• Find the plastic push-pin retainers holding the lamp to the body.
• A push-pin retainer is a plastic clip with a center pin that expands the clip when installed.

Step 2: Remove the left lamp retainers

• Use the plastic trim removal tool to gently lift the center pin of each retainer.
• Use your fingers to pull the retainer body out once the center pin is raised.
• Place the retainers on a shop towel so they do not roll away.
• Torque to hand-tight only when reinstalling plastic retainers.

Step 3: Remove the left rear lamp housing

• Use both hands to hold the lamp housing firmly.
• Pull the lamp straight rearward, away from the vehicle.
• Do not pry against the paint with a metal tool.
• The outer side uses alignment pins, so the lamp should come straight out.
• Pull steady, not sharply.

Step 4: Remove the left rear turn signal socket

• Use the flashlight to identify the turn signal bulb socket on the back of the housing.
• The turn signal socket is the socket for the amber flashing lamp.
• Use your hand to turn the socket counterclockwise about one-quarter turn.
• Pull the socket straight out of the lamp housing.
• A bulb socket is the plastic holder that locks the bulb into the lamp.

Step 5: Replace the left rear turn signal bulb

• Use clean nitrile gloves to grip the old bulb.
• Pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb straight into the socket until it is fully seated.
• If the bulb has a wedge base, it simply pushes in and pulls out.
• A wedge base is a flat plastic bulb base with metal contacts on the sides.

Step 6: Reinstall the left turn signal socket

• Use your hand to insert the socket into the lamp housing.
• Turn the socket clockwise about one-quarter turn until it locks.
• Confirm the socket sits flat and does not wobble.

Step 7: Test the left rear turn signal

• Use the turn signal stalk to switch on the left turn signal.
• Stand behind the vehicle and confirm the left rear turn signal flashes normally.
• Turn the signal off before reinstalling the housing.
• If an LED replacement bulb does not light, use clean nitrile gloves to remove it, rotate it 180 degrees, and reinstall it.

Step 8: Reinstall the left rear lamp housing

• Use both hands to line up the guide pins with the body openings.
• Push the lamp housing straight forward until it sits flush with the body.
• Use your hand to reinstall the plastic retainers.
• Push the center pins down until they sit flush.
• Torque to hand-tight only; do not over-force the plastic retainers.

Step 9: Replace the right rear turn signal bulb

• Use the flashlight to locate the right rear lamp retainers.
• Use the plastic trim removal tool to lift the center pins and remove the retainers.
• Use both hands to pull the right rear lamp housing straight rearward.
• Use your hand to turn the turn signal socket counterclockwise about one-quarter turn.
• Use clean nitrile gloves to pull the old bulb straight out.
• Push the new rear turn signal bulb straight into the socket until seated.
• Use your hand to reinstall the socket and turn it clockwise until locked.
• Use both hands to align and reinstall the lamp housing.
• Use your hand to reinstall the plastic retainers and push the center pins flush.

Step 10: Final function check

• Use the turn signal stalk to test the left rear turn signal.
• Use the turn signal stalk to test the right rear turn signal.
• Use the hazard light switch to confirm both rear turn signals flash together.
• Check that both rear lamp housings are flush and secure.

✅ After Repair

• ✅ Confirm the turn signals blink at a normal speed.
• ✅ If one side blinks very fast, that usually means the bulb is not seated, the wrong bulb is installed, or an LED bulb is not compatible.
• ✅ Check the instrument cluster for any bulb-out warning.
• ✅ If using LED bulbs, make sure they are CAN-bus compatible to avoid warnings or hyper-flashing.
