The fuses are typically located in two places:
* Under the hood: A larger fuse box is usually located under the hood, often near the battery.
* Inside the cabin: A smaller fuse box/panel is often found inside the vehicle, usually under the dashboard on the driver's side.
To find the correct fuse(s) or circuit breaker:
1. Locate your owner's manual: This is the most reliable source. The diagram will show you the fuse/breaker layout and what each one controls.
2. Look for terms like: "tail lights," "parking lights," "dash lights," "instrument panel lights," etc. The relevant fuse(s) will be labeled accordingly.
3. Check both fuse boxes: Don't just check one. Some circuits might be split between the boxes.
Without your owner's manual, I can't give you a definitive answer. Searching online for a "1998 Chevy Sonoma fuse box diagram" might yield a helpful image, but always cross-reference it with your manual if you have one. Remember that the specific layout can vary slightly depending on the trim level and options your truck has.
