To find your headlight fuse, you'll need to consult your owner's manual. This is the most reliable source. The manual will show you a fuse panel diagram with labels identifying each fuse and its function.
If you don't have the owner's manual, you can try these common locations, but be aware there's no guarantee your headlights' fuse will be in any of them:
* Under the hood: This is the most likely location for at least *some* fuses, including potentially those for headlights. Look for a fuse block often near the battery. It may be covered, so check for a panel or lid.
* Under the dash: Some fuse panels are located under the dashboard, often near the steering column or the instrument panel.
Important Considerations:
* Multiple Fuse Boxes: Some models might have more than one fuse box. Look carefully.
* Relay: Headlights often use a relay in addition to a fuse. A failed relay can also cause headlights to stop working. If you check the fuses and they're good, you'll want to investigate potential relays. The relay is usually a small square or rectangular box often near the fuse box(es).
* Wiring Issues: Before replacing fuses and relays, make sure you haven't got a broken wire somewhere in the headlight circuit.
Without the owner's manual, finding the specific location will be more difficult. Online resources like a Pontiac Bonneville forum or a repair manual specific to your year and model could help, but the owner's manual remains your best bet.
