š Before You Begin
- Park your Encore on a flat surface and set the parking brake.
- Open the rear liftgate for access to the tail lamp screws.
- Apply painterās tape on the painted edge near the tail lamp. Prevents accidental scratches
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Access the tail lamp fasteners
- Open the liftgate.
- Locate the two tail lamp screws on the inboard edge of the tail lamp (visible with the liftgate open).
- Use a 7mm socket with a 1/4" drive ratchet and 3" extension to remove both screws.
Step 2: Remove the tail lamp assembly
- Grip the tail lamp with both hands and pull it straight rearward (away from the body).
- If it feels stuck, use a trim removal tool (specialty) to gently help it release. A trim tool is a plastic pry tool that helps remove panels without damage.
- Do not twist the lamp; itās held by alignment pins that need a straight pull.
Step 3: Remove the turn signal bulb socket
- On the back of the tail lamp, find the turn signal bulb socket (usually the amber/bigger bulb position).
- Use your hand to rotate the socket counterclockwise about 1/4 turn, then pull it out.
- Use a flashlight to confirm you have the correct socket before removing the bulb.
Step 4: Replace the bulb
- Wear nitrile gloves to keep oils off the bulb glass.
- Pull the old bulb straight out of the socket.
- Push the new rear turn signal bulb (amber) straight into the socket until fully seated.
- Apply a tiny amount of dielectric grease to the socket seal (rubber O-ring area). Dielectric grease helps keep moisture out and prevents corrosion.
Step 5: Reinstall the socket and tail lamp
- Insert the bulb socket back into the tail lamp and rotate clockwise to lock it.
- Align the tail lamp pins with the body grommets and push the lamp straight in until it seats flush.
- Reinstall the two screws using the 7mm socket and 1/4" drive ratchet.
- Tighten snug only. Overtightening can crack the lamp
Step 6: Repeat on the other side
- Repeat Steps 1-5 for the other rear tail lamp so both bulbs match brightness and color.
ā After Repair
- Turn the ignition ON and test the left and right turn signals.
- Verify the turn signal flashes normally (not fast). Fast flashing usually means a bulb isnāt working or isnāt seated.
- Turn on the hazard lights and walk around to confirm both rear signals blink evenly.
- Check that the tail lamp sits flush and the liftgate closes without rubbing.
