How to Install a Turn Signal Flasher on a 2001 Pontiac Sunfire

The 2001 Pontiac Sunfire has turn signal flashers at the front and rear. The front turn signals need 4157NALL bulbs to work properly, and the rear turn signals need 3157-type bulbs. Any other bulbs may damage the electrical system of the vehicle. You will need a Phillips screwdriver and a socket wrench to install the turn signal flashers on the Sunfire. The entire procedure takes no more than 15 minutes to install both turn signals.

Things You'll Need

• Phillips screwdriver
• Socket wrench
• Clean rag
• Replacement bulbs

Instructions

1. Turn off the Sunfire's engine and open the hood.

2. Remove the plastic shield covering the headlight using a screwdriver to pry it out.

3. Remove the two bolts anchoring the headlight assembly using a socket wrench.

4. Pull the headlight assembly as far out of the vehicle as you can. Reach behind the turn signal assembly below the headlight assembly and rotate the turn signal socket counterclockwise to remove it. Pull the old bulb out of the socket.

5. Install the new bulb into the socket using a clean rag. Do not touch the glass surface of the bulb. Place the socket back into the turn signal assembly.

6. Place the headlight assembly back into the vehicle and reattach the two bolts. Reattach the plastic shield and close the hood.

7. Open the trunk. Remove the fasteners holding the trunk trim with a Phillips screwdriver. This will allow you to access the taillight assembly.
