🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear tail lamp screws

• Open the tailgate.
• At the inboard edge of the tail lamp (the side facing the tailgate opening), remove the two retaining screws using a Phillips #2 screwdriver.
• If your lamp uses bolts instead of screws, remove them using a 10mm socket and 1/4" drive ratchet.

Step 2: Pull the tail lamp assembly straight back

• Hold the tail lamp housing with both hands and pull it straight rearward.
• If it feels stuck, use a trim panel tool (plastic) (specialty) to gently help it release from the alignment pins (plastic locating posts).
• Pull straight back to avoid breaking pins.

Step 3: Locate the turn signal bulb socket

• Look at the back of the tail lamp and find the socket for the turn signal (usually the amber/turn position).
• Twist the socket counterclockwise about 1/4 turn, then pull it out by hand.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket by hand while wearing nitrile gloves.
• Install the new bulb by pushing it straight in until fully seated.
• Add a very small amount of dielectric grease to the socket seal area (not on the bulb glass).
• Match the old bulb style exactly.

Step 5: Reinstall the socket and tail lamp

• Insert the socket back into the housing and twist clockwise until it locks.
• Line up the tail lamp alignment pins with the body and push the lamp straight in until it sits flush.
• Reinstall the two screws using a Phillips #2 screwdriver (or bolts using a 10mm socket and 1/4" drive ratchet).
• If using a torque wrench, tighten the lamp fasteners to Torque to 5 Nm (44 in-lbs).

✅ After Repair

• Turn the ignition to ON and test left and right turn signals, hazards, and brake lights.
• If the turn signal blinks very fast, the bulb may be wrong type, not seated, or another bulb on that side is out.
• Confirm the tail lamp is fully seated and even with the body (no gaps).
