How to Change a 2002 Buick Century Front Turn Signal

If you own a 2002 Buick Century, you eventually will have to replace one of the front turn signals. You could have a mechanic or local Buick dealership replace it, but you can save the expense by doing it yourself.

Difficulty: Moderately Easy

Instructions

1. Purchase a replacement bulb from an auto parts department or auto parts store. The bulb number is 4157NAK. You also can check the parts book or ask store employee for assistance.

2. Open the hood of the vehicle. The hood release handle is located under the dash on the left side of the vehicle. Once you discharge it, you must free the second hood release under the hood of the vehicle in the center. Move it to the right and lift the hood.

3. Locate two headlamp retainers (clamps) holding the headlamp in place. Pull up to remove them to discharge the tabs on the assembly.

4. Detach the power to the headlamp. Now you can easily remove the assembly out of its position.

5. Take off the rubber cover located in back of the turn signal light. This will allow access to the bulb socket.

6. Turn the light socket counterclockwise to remove it from the assembly.

7. Remove the old bulb by holding the bottom of it and pulling it gently up. Replace with new bulb.

8. Once you have replaced the bulb, put the light socket back in the assembly and turn it clockwise to secure it.

9. Replace the rubber covering on the back of the headlamp assembly.

10. Put the headlamp assembly back in place by sliding it in the slot and attach the power supply.

11. Replace the retainer clamps to hold the headlight assembly in place and close the hood of the vehicle.

Tips & Warnings

• If you notice either of your turn signal lights blinking a little faster than usual, this is an indicator that you need to replace the signal.
• If the turn signal light does not come on when you apply them, you may have a burned bulb or fuse.
